Preheat your oven for a classic flourless Monster Cookies recipe that’s been in my family for more than two decades.
Chocolatey, chewy, peanut buttery goodness. There’s no better way to describe this tried and tested family recipe for Monster Cookies.
My mom got this recipe from a friend more than 25 years ago, and it’d be impossible to count just how many dozens of Monster Cookies have been baked and enjoyed since that glorious recipe exchange.
These cookies became a staple of mine when I was in college and grad school, and to this day, I’m remembered for their impossibly chewy and soft texture, and of course their unbeatable taste.
My husband jokes that these are a healthy dessert, courtesy of the lack of flour and addition of oats and peanut butter. While “health food” may be a stretch, you can guarantee they are a crowd-friendly dessert. (But if you are looking for a healthy sweet, don’t miss my famous 5-Minute Frozen Yogurt!)
The creepy candy eyes are an optional addition, but they’re a festive decorative touch in October when all things Halloween rule the food scene.
No stand mixer? No problem! I made these cookies dozens of times all through college sans mixer. (Consider the stirring your workout for the day.) And both smooth and chunky peanut butter will work, but I love the added crunch that chunky offers.

I love love love this recipe.
Can I freeze the dough after portioning it out? If so, will it affect the texture of the oats?
Thrilled you’re enjoying it, Sarah! And yes, this recipe freezes like a breeze. Enjoy!
If I freeze the dough after portioning it out and freezing, what is the best way to bake them? Should I let them thaw first? Or can I bake them from frozen. Time and temp?
Thank you so much!
Hi Sarah! You can bake them directly from the frozen state at 325°F and I’d add roughly 5 minutes to the bake time. Hope this helps!
These are the best cookies!!
One is never enough
Love reading that, Lori!
They turned out lovely, question – are they gluten free? Thank you
Hi Carol! As long as you are using oats that are designated as “gluten-free,” then they should be a GF-friendly treat!
Love! My family and co-workers new favorite!
So glad you all enjoyed it, Stephanie!
Amazing! Made them with regular sized m&ms since I didn’t have any minis and they were excellent! Will make sure I have minis on hand to try next time
So glad you enjoyed the recipe, Beth!
These cookies are amazing! I made them for my schools blood drive for the kids who donate and I had none left at the end of the day!
Love reading this, Jayden!
Easy and delicious. I’ve made this recipe several times, it’s always a winner. FYI-I mix creamy and chunky peanut nut butter.
So glad you enjoyed it, Robin!
Great easy cookies! Family loved them and they held up in freezer.
Thrilled you all enjoyed them, Michelle!
I made these cookies for Christmas 2024 and I must say they are the best cookies I’ve ever
eaten!! They are chewy and Delicious!!! I even added a few butterscotch chips and loved it! The options are almost endless. Thanks so much for this recipe!
Love reading this, Donna!
We make these way too much! The best cookies- our fam’s favorite. Also a great gluten free option
So glad you’re enjoying the recipe, Ashley!
Me and all my cotmers and family love these
So glad you all enjoyed it, Bella!
Hi, there. Have you ever frozen the dough??? If so, would I bake them straight from the freezer or thaw and then bake?
I had great success making these smaller using the small cookie scoop that’s 1 1/2 tablespoon. In my oven, I baked them for 11 1/2 minutes. YOU ABSOLUTELY MUST LET THESE SIT ON THE BAKING SHEET FOR AT LEAST 30 minutes to set up properly. Longer for the 3 tbsp size cookies.
Excellent recipe that allows you to experiment with add-in’s.
Thank you for sharing.
So glad you enjoyed it, Lisa! Yes, I’ve frozen it before. To bake from the frozen state, you’ll just need to add a few more minutes to the bake time. Enjoy!
I have a recipe very similar to this from who knows when. I can hardly read the recipe card any longer. But this is a smaller batch. I just made my recipe with my grandson to earn a badge. So I’ll have to wait and try your recipe some time later. But thank you for this.
Enjoy, Shar!
How to cook at 325° instead of 350° because it was starting to burn the bottom of the cookies
Whenever I make sourdough bread I always put another pan or pizza stone on the bottom rack. It never burns the bottom of the bread anymore. Maybe it will work the same for cookies
Great idea, Susan!
My favorite monster cookie recipe! I get compliments whenever I bring them anywhere!
So glad you’re enjoying them, Alicia!
Best cookie recipe ever! I’ve never really liked baking cookies but this one is so easy and everyone loves them! My granddaughter gives them a solid 7.5-8. I give them a 10+.
Love that you’re both enjoying the recipe!
I make these cookies also, definitely one of my favorites. In mine though I also add a cup of raisins, then along with the eyes, I also give them gummy worm smiles. I would send a picture but I don’t see any place to do that.
Thanks
Steven.
Just got your picture via email, Steven! Love it!
These are so delicious. I will definitely be making them again.
Thrilled you’re enjoying it, Debbie!
Love this recipe. Made it all the time, then wife went vegan; now i make them vegan (use 1:3 tbsp flax seed to water and dark chocolate instead of milk). Good recipe, can do a lot of variations.
So glad you enjoyed it, Andrew!
I have a recipe from the 80’s but it makes a huge batch. This is the first smaller batch recipe that turns out like my recipe! These are great! Thank you!
So glad you enjoyed the recipe, Kathy!
Made these last night and they are so good, crispy edges but a soft and chewy center I will be making these again. Thank you for this yummy recipe!
So glad you enjoyed it, Alyssa!
I add one ingredient to this recipe and it has become everyone’s favorite
So glad you are enjoying the recipe, Jarines!
Made and sent to my new son-in-law who is Air Force and training in special forces. They traveled well but I did individually wrap since it is going into heat! He loves them and they are a special homemade treat that satisfies!
Love reading this, Brenda! So glad your son-in-law enjoyed them!
YUM!!! Always popular.
So glad you enjoyed it, Sandra!
Love this recipe!
Thrilled you’re enjoying it, Kathy!
These are by far the most favourite cookies. My children & grandchildren agree
So glad you enjoyed the recipe, Lori!
Delicious and easy to make!
So glad you enjoyed it!
Easy and wonderful!
Thrilled you enjoyed the recipe, Tonya!
I make these over and over. They are always a hit!
Love reading this, Kristin!
I must update my review! I made these last Sunday and they were so good I made them again this Sunday! I hate it when people talk about all the changes they make to recipes to the point it is not even close to the same thing! I do however have to share a change I made though, because it added SO MUCH texture to the cookies! I didn’t have enough oatmeal and I didn’t want to run to the store in the middle of preparing these, so I added a cup of crushed up Corn Flakes! I don’t know if crushing them was necessary, but I thought it would be best to make it the size of the oatmeal. Let me tell you!!! I will do this again and again! It was so good! I used a half cup measuring scoop filled about 3/4 full and flattened them a little bit. It made about 16 cookies.
I’m so glad you enjoyed the recipe, Rebecca!
This will be my “go to” monster cookie recipe! They turned out great!
I’m so glad you enjoyed the recipe, Michelle!
Wonderful chewy cookies! Didn’t change a thing!
I’m so glad you enjoyed them Rebecca!
Perfect! I made 3″ cookies and ended up with a few extras. I took them out and flattened them before baking for the final 2 minutes.
I’m so glad you enjoyed the recipe!
This is by far the best monster cookie recipe I have ever used. They are so soft and delicious, they go too quickly so I have to make multiple batches every time!
I’m so thrilled to read that, Kristin!
This recipe turned out great!! I was worried they’d crumble with no flour but they look exactly like the pictures!
I’m so happy you enjoyed the recipe, Bree!
I searched for this recipe. A former coworker had given it to me and, over the years, I’ve managed to lose it. It needed to be THIS recipe because my daughter and I are sensitive to gluten, and this recipe can easily be gluten free since it doesn’t have flour. Heading to the kitchen now to make a batch. YUM!
Very good!! My oven is getting pretty old so it was a fine line for me to get them done in the middle but not overdone so they were still soft and chewy. I must have did ok though because my test group (the guys at work) told me to make sure to keep this recipe! Love that this recipe has more peanut butter; yum!
I’m so glad you enjoyed the recipe, Rachel!
These were so delicious! I tried blending 2 cups of the oats in the food processor and pushing the dough balls down and the results were 100/10. They are incredibly good.
I’m so glad you enjoyed the recipe, Krista!
I made I few minor changes to your awesome recipes, I wanted to share. I swapped one cup of oats for one cup shredded coconut, and bag of Reese’s peanut butter baking cups and candy 8.5oz bag for the candy and mini chocolate chips. And when I make them for my daughter who is allergic to chocolate I use Reeses pieces and peanut butter chips
So glad you enjoyed the recipe, Missy!
I made these for a Friendsgiving in 2023. They were a total hit and when my buddy asked if he could take the leftovers to another event that weekend, I was fine with it. They were completely gone before the night was over with the hostess complimenting my buddy on the cookies. This recipe will be in my holiday cookie rotation moving forward.
Thank you for sharing this recipe!
Thrilled you all enjoyed the recipe, Donnie!
Hello, mine turned out super flat after 15 minutes. I put the mixture in the fridge for 20-30 minutes prior and it was moist, almost falling apart when I spooned them on the tray. Where did I go wrong? Maybe over beat the sugar and butter at the beginning? Still tasted great, just wanting to perfect the presentation.
Hi Anh! It sounds like your butter was too warm.
These are fantastic cookies – super moist, tasty and turned out just like the pics!
Can you sub in something else to replace the peanut butter if there is a nut allergy?
I’m so thrilled you enjoyed the recipe, Asha! I’ve never tried a different type of butter (like sunflower seed), so I’m not sure!
I either did something wrong or I’m not a huge fan of all oats/no flour cookies. The middle seems not done? Is that how it’s meant to be? The only thing I can think I might have made a mistake with is creaming the butter and sugars. My butter sat out for an hour prior to using but it still was somewhat cold. I wasn’t able to get a “light and fluffy” texture creaming it with the sugars as the recipe describes. Is this where I went wrong!? Either way the flavor is still amazing!! Just wish the middle of the cookies didn’t seem so “raw”.
Hi Kristi! Did you confirm your oven temp was correct and your rack was in the center? It sounds like a temperature issue!
I love these cookies! I have made them many times. I had a craving for them today but not enough m&ms so I added what m&ms I had and threw in some Reese’s pieces for good measure. Yummy! Thanks for sharing this recipe.
I’m so thrilled to hear that you enjoyed the recipe, Becky!
Can these be put in freezer after baking?
Absolutely, Ronna! Just let them cool completely before packaging them in an airtight container.
Hi! I was wondering if there was a way to half this recipe? I know it calls for three eggs, and I’m not sure if it’s possible to only make a half batch. Thanks!
Hi Emerson! Halving the egg gets tricky, however this dough freezes beautifully and will last for months if stored in an airtight container.
Hello Kelly,
I’ve made monster cookies for years and years. The recipe I normally use is from an old church cookbook. The main difference is the old recipe calls for a spoon of Karo syrup. I’m not sure why it calls for it.
I’m going to use your recipe this time. I’m sure my grandchildren will love them.
Thank you for sharing your recipe, MaryAnn
Hi, MaryAnn! Let me know how the cookies turn out when you and your grandchildren try them!
My new go-to cookie recipe. They’re the first to be eaten at Christmas.
I’m thrilled to hear that you enjoy the recipe, Sandy!
Taste great. Soft and chewy with just a bit of crunch. I reduced the sugar, seems like you can do that in many recipes and they’re still great. And, for a little salty crunch, I threw in some crushed up pretzels. Complements the peanut butter and chocolate well.
I’m so glad to hear that you enjoyed the recipe, Kristin! The added pretzels sounds great!
So easy to make! Makes so many cookies. Changed absolutely nothing! Make them whenever we visit our daughter at college, all her friends ask if we’re bringing over the cookies.
I’m so thrilled you all are enjoying the recipe, Leesa!
No flour?
Correct! No flour needed in this recipe.
Delicious and addictive! I only use 1/2 or even 1/4 of the sugar though and they are still plenty sweet!
So glad you enjoyed the recipe, Rach!
I was thinking of reducing the sugar too. So it didn’t affect texture or bake time, etc.?
Hi Mary Ella! I haven’t tried reducing the sugar so I’m not sure what the outcome would be.
What if I decide to make the cookies smaller, only one scoop? How long should they bake?
Hi, Suzanne! The baking time will depend on what size your one scoop measurement is!
The last time my mom made monster cookies was a few days before her 50th wedding anniversary party. She left us and went to heaven 5 mins into the day of the party. Today is Thanksgiving and she made monster cookies for every holiday for 30 years. I made your recipe today to surprise my nephews. The tradition must continue. Happy Thanksgiving from Wisconsin.
This makes me so happy, Rebecca. Thank you for sharing such a sweet memory. I hope you all had a wonderful Thanksgiving!
the recipe was really easy and the cookies tasted great
I’m so glad that you enjoyed the recipe, Victor!
These are AMAZING! I found my new favorite cookie! Plus, since it has oats in it, I consider it a breakfast cookie. Win-win! :) Plan on doubling this recipe because they disappear as fast as they come out of the oven! Thank you for sharing!
I’m so thrilled to hear that you enjoy the recipe, Michelle!!
One of my favorite cookies to make for the holidays!!
I’m thrilled to hear that you enjoy the recipe, Christia!
They turned out perfect!! This will now be my go to recipe for Monster Cookies!!
I’m so happy to hear this, Shannon and that you enjoy the recipe!
this is the best monster cookie recipe ever. I was wondering what can i do to make it a little less dry?
Hi Teagan! So glad you enjoyed the recipe. Did you use the amount of butter and peanut butter listed in the recipe? The cookies definitely won’t be dry if you follow those amounts!
Perfection. Just wonderful. Exactly what I was hoping for soft and delicious. Definitely need to leave the cookies on the pan for the 5 minutes after they come out of the oven! Thank you!!
I’m so glad to hear that you enjoy the recipe, Andrea!
Added caramel bits and used full size choc chips and M&Ms. My coworkers are begging for more. Might try a batch adding in pretzel balls. I also froze some dough and it baked well, in case anyone else wonders.
I’m happy to hear that you enjoyed the recipe!!
LOVED this recipe. We did 3/4C m&m’s, 3/4C white chocolate chips, and 3/4C of Reese’s Pieces. I scooped small cookies out, and pressed down just a little bit. They were the perfect treat for a Halloween party. It was a candy overload, but that was by design! They come together quickly and my 8yo daughter and I had a great time making them. Thank you for the wonderful recipe.
I’m so thrilled to hear that you and your daughter enjoyed making them and that they were a hit at the party, Nalani!
Amazing! I had so many compliments on these! Wouldn’t recommend doubling the recipe as it will way oveflow your mixer. Single batch is plenty. These cookies are huge and filling. I prefer smarties over m&ms.
So glad you enjoyed the recipe, Allison!
Love these cookies! Unfortunately, my cookies are not spreading and stay as mounds which takes longer to bake. I pressed the rest of the batch down prior to baking to get a thinner cookie.
Glad that trick worked, Kathy!
OMG! I had never made monster cookies before this and they were so good. So good I am making my second batch. This time I used half of the MM’s and Mini-chips, and replaced it with chopped pecans and hazelnuts. Off the hook.
I’m so thrilled to hear that you’re enjoying the recipe, Ziggy! Great idea adding the chopped pecans and hazelnuts!
Great cookie, easy recipe. At my husband’s amateur radio club’s potluck dinner, they were a huge hit!
I’m so happy to hear that you enjoyed the recipe and that they were a hit, Vici!
Making these today. I use 1/2 cup each of mini m&ms, Reese’s pieces, mini chocolate chips, and white chocolate chips. They are great cookies.
I’m so glad you enjoyed the cookies, Stephanie!
Made these with Equate peanut butter powder (equivalent to PB2) instead of BP. Just to lower the calories. Turned out great!! I will make again!
I’m thrilled to hear that you enjoyed the recipe, Merry!
Great cookies!
So glad you enjoyed the recipe, Jenny!
Thanks for the recipe. Didn’t know it was GF! The Amish women sold monster cookies from a stand in the mall when I was growing up in small town Indiana. Such a treat!
Yes, natural peanut butter, freshly ground, works great. 3/4 of the sugars was sweet enough for me. I also subbed out toffee pieces instead of M&Ms; they have gotten so expensive! Admittedly, I missed the crunch of the M&Ms. Hopefully the Great Pumpkin will bring me some for Halloween.
You are so welcome, Alice! I’m thrilled you enjoyed the recipe and I love the idea of using toffee pieces!
So delicious, and exactly how I remembered them from being a kid! It’s our new favorite cookie recipe!
Yay! I’m so thrilled you enjoyed the recipe, Elise!
These are delicious cookies and this is the 2nd time I made them but this time they spread out and became thin. The first time they were perfect! I have gone over all the ingredients and I followed to a t but can’t figure out what went wrong this time. The taste is wonderful though.
Hi Sadie! Did you let the melted butter cool for 15 minutes before continuing with the recipe?
A bit too much peanut butter, I feel, but overall a wonderful cookie! Take the tip to let them cool…that worked wonders. I gave 10mns before I started to store them away. Yum!!
Love these! I make Monster cookies for many friends and family! This is no my very favorite flourless recipe! Thanks!
Have made these multiple times and they don’t last long. Have made these with a peanut butter monster mix and takes them to another level!! So good!!!
Our household loved these!
I did not end up having enough oatmeal (about 3 cups) and subbed in about 1.5 cups of flour to make up the difference. I also opted to add all the leftover chips I had around the house, white, dark and butterscotch and added them with the few m&ms I had left. Essentially, I think they are more “trash can” cookies – but absolutely amazing!
Also, take the tip to take them out when still soft and letting them sit on the cookie sheet, they’re so much better chewy!
Woohoo! So thrilled you enjoyed the cookies, Cassidi!
Even if you want the double batch make them one at a time because it just does not fit in a stand mixer bowl :)
I took some to my daughter in college her boyfriend asked her if I bring a container will your mom fill it for me! They’re fast they’re easy and they’re delicious.
Thanks for your note, Lee!
This is our favorite Monster Cookie recipe! Thanks for sharing!
You are so welcome, Tracy! I’m thrilled you’ve been enjoying the recipe!
Can you make this with sugar free or natural peanut butter? I’ve only ever tried it with Jiff/Skippy peanut butter and they turned out great. I just only have sugar free on hand at the moment.
Hi Madelyn! Great question! I’ve never made it with sugar-free or natural peanut butter, but I know a lot of people who have tried and they said the texture just isn’t the same. Sorry to report that!
Love this recipe, best one out there for monster cookies. Everyone says it’s a hit.
So glad you enjoyed it!
So yummy! I had a problem with them wanting to stay round and not flattening out. Any advice on how to prevent that and why that would happen? Everyone loved them!
Hi Tania! – There are several factors that may have attributed to your cookies not flattening out, such as how the heat circulated in your oven, your type of baking sheet and whether you used parchment paper or a Silpat. Perhaps next time you could flatten the dough slightly (after you’ve portioned it out)? Sorry!
Perfection! Made exactly as instructed. My husband said this cookie is his new favorite.
Woohoo! I’m so happy to read this, Helene!
Why does the butter and sugar take SO LONG to cream together? it’s been 30 minutes and still not light and fluffy!!
Hi Kaitlyn – Did you start with room temp butter? You only need to beat the butter and sugar together for about 2 to 3 minutes at a moderate speed:)
Ooh, these are delicious!
I added a little more salt (an additional 1/2 tsp) per another comment, since I like a good salty/sweet balanced cookie.
Everyone lived them!
I added a half a cup of mini marshmallows just for fun…..I will grease the cookie sheet better next time….super sticky, but delicious.
Yay! I’m so glad you enjoyed the recipe, Lyndie!
I got this recipe from my mother 40 yrs ago and my family demands them as often as I can make them . I’m not a big peanut butter fan, but the combo of m&ms and chocolate chips makes them the best. Easy to make, a delight to eat.
I love a recipe that’s been around for generations! :)
These were fun to make. I do not own a stand-up mixer, so I had to use old fashioned arm strength. I substituted some of the chocolate chips with white chocolate chips instead for the heck of it.
I eyeballed the three to four tablespoon size dough balls, and they still looked good! Who doesn’t love a little diversity in their cookie sizes. <3
I cooked some at the recommend time of 12 to 15 minutes to see how those turn out consistency wise. They came out a lovely golden brown with crispy edges. The aromas were all peanut butter when the oven opened! I let them cool for five minutes before I had one myself and they are suuuuper rich. They have a nice crunch and a gooey interior! Absolutely delicious!
I also cooked some the way Kelly suggested as well because my husband loves chewy, soft cookies. I only baked them for 11 minutes and 30 seconds. They turned out a soft sandy color, not golden like the 12–15-minute baked ones. These cookies are fall apart soft. I couldn't wait ten minutes to have one, but it is a must if you want them to keep their form!! These are melt-in-your-mouth gooey. So much softer than the others. My husband says they're amazing, but I prefer the 15-minute ones.
So, all together, I give this a 5/5! Even better with a glass of cold milk! I'm going to be making these again guaranteed.
Love, love, LOVE reading this, Madi! I’m thrilled you and your husband enjoyed the cookies!
These cookies turned out amazing!! So so delicious perfect timing finding your recipe too! Great addition for my kids teachers for teacher appreciation week. Definitely adding these to our cookie rotation.
Woohoo! I’m so thrilled you enjoyed the recipe, Carolyn!
The best cookies !
yum
The BEST cookies ever!! My family devoured them!!
Woohoo! I’m so thrilled your family enjoyed the cookies, Shelly!
WOAH these are amaaaazing!!!! Everyone loved them! This will be my go to recipe forever and ever. Thank you!!!!
This is what I love to read, Brittany! I’m so thrilled you enjoyed the recipe!
These were good cookies however I thought they were a little too sweet and they needed some more salt. I like their chewy texture.
I’m glad you enjoyed the cookies, Marilyn! Feel free to add more salt next time :)
Is it necessary to use mini chocolate chips and mini M&ms?
Regular-sized work too, Lori!
So yummy and gluten free that I can eat way too many. Definitely a great recipe for sharing lots of great cookies with my mail carrier, friends and neighbors. My daughter requests these regularly for her and her boyfriend. Thank you for sharing your recipe with us baking folks!
You are so welcome, Lorel! I’m thrilled you enjoyed the cookies!
We love these cookies! I used PB fit powder for lower fat and calories. I increased the oats to thicken the cookies.
Delicious!
Awesome! I’m so glad you enjoyed the recipe, Nicole!
How much pb fit did you use to sub?
My husband favorite cookies. He loved it.. It’s chewy and yummy .Thank you for the recipe
You are so welcome, Nadja! I’m thrilled you and your husband enjoyed the cookies!
Made 24 “monster” sized cookies with ice cream scoop. Pressed top down to flatten a little. Could easily double amount with smaller scoop. Baked for 11-12 mins, let stand for 5+ mins then racked. The may seem “mushy” but oats will soak up and set up cookie. Move to rack to cool fully. Will stay soft and chewy days later. Great chocolate and PB flavor. Oats add a nice texture. Nice that they are flourless. Also freeze very well. Everyone enjoyed immensely with Ice Cream and asked for recipe. Highly recommend. BJS
This is what I love to read, Barry! I’m so thrilled you enjoyed the recipe!
Very good. Easy to make. I used an ice cream scoop to get the 3 Tbls of cookie dough before baking.
I’m so glad you enjoyed the recipe, Joy!
These are amazing! Didn’t have enough chocolate chips so I emptied bags of chocolate, butterscotch, and white chocolate (full size). Making them even more monster! Love they are GF also. Thanks for the recipe.
YUM! I’m so glad you enjoyed the recipe, Marsha!
They are the perfect cookie in my mind. My celiac friends are also big fans! Ivr made them 3 times now and perfect each time. Thank you!
You are so welcome, Jorme! I’m thrilled you (and your friends!) have been enjoying the recipe.
Mmmm these are exactly what I wanted. So chewy and delicious, thank you for this recipe! I even froze the doughballs and made a couple at a time, and they still turned out amazing.
You are so welcome, Steph! I’m thrilled you enjoyed the recipe!
Toooo much sugar!! Made them so sweet and a little too runny. Delicious otherwise!
Thanks for your note, Elizabeth. Try reducing the sugar amount by 25% next time :)
I just made this scrumptious cookie only a Sugar Free verison . I switched the sugar for 1 cup Erythritol , the brown sugar for 1 cup Swerve brown sugar, the peanut butter for no sugar added peanut butter and the chocolate chips and M&MS for Lily’s chocolate chips. They turned out beautifully. Thank you so much for the delicious recipes. Hope someone finds my version helpful\useful.
Amazing! Thanks so much for your comment, Tina. I’m thrilled you enjoyed the cookies!
I really love how easy these are to bring together it’s a one-pan deal no measuring flour. They’re super good the kids love them the adults love them they’re easy to make and the single batch makes a lot of cookies. I just changed the color of Eminem’s for the occasion reds for Valentine’s greens for St Patrick’s Day red white and blue for the 4th of July etc
I’m thrilled you’ve been enjoying the recipe, Megan!
The BEST monster cookies I’ve ever had. I recently had to go dairy free while breastfeeding so I made them with dairy free butter and chocolate chips and they were amazing! The texture was a little different but my husband thought they tasted just as good! Thanks for the amazing recipe!
You are so welcome, Taryn! I’m thrilled you and your husband enjoyed the cookies!
Love making the monster cookies. Have been making them for a long time.
I’m thrilled you’ve been enjoying the cookies, Pauline!
Oh boy, so good!!! I ate way too much cookie dough, then I ate 2 cookies waiting for them to cool. Safe to say I’m skipping dinner tonight, I’m full from cookies. Easy to make and so delicious
I’ve been there! I’m thrilled you enjoyed the recipe, Jenny!
I was hungry for cookies, and have had to go gluten free. I couldn’t find my mom’s recipe for monster cookies, and found yours online… almost identical! I made a smaller batch (about 1/4th batch), and actually did these in my air fryer (350 degrees for 5-6 minutes). My air fryer is only 2 qt, so only made one or two at a time. (I made 9 cookies lol). I also added about 1 TBL of apple sauce to keep them softer. They are so delicious! And gluten free, as long as you check your other ingredients. I have since found my Mom’s recipe, and they are identical lol… guessing these have been around for decades.. I know Mom used to make them for us for Christmas, along with the sugar cookies lol. Thank you so very much for the recipe and the memories.
Love this, Charlotte! I’m so thrilled you enjoyed the cookies. :)
A hit at our house! Quick, easy and yummy!
I’m so happy to read this, Connie!
Always a crowd pleaser!
I’m thrilled you’ve been enjoying the recipe, Amanda!
Awesome cookies and my family loved them. Happy they are gluten free too.
I’m so glad your family enjoyed the cookies, Sheryl!
Very good, SUPER EASY, ingredients you’ll have on hand, great to bake for large crowd!
YESSSS! I’m so thrilled you enjoyed the cookies, Leesa!
The best Monster Cookies ever!!
Woohoo! I’m so thrilled you enjoyed the recipe, Mary!
Fantastic. Bake them every 6 months for the family!
I’m so thrilled you’ve been enjoying the cookies, Barb!
When my husband was stationed in Misawa, Japan, 37 years ago, we bought a girl scout troops recipe book that had Monster Cookies recipe in it. They were so good that we have been making them ever since. You haven’t lived until you have eaten a Monster cookie! Thank you so much for keeping this recipe alive. Some recipes need to be handed down through the time, and this is one of them.
YES! The best recipes stand the test of time.
Is it better to use quick oats or old fashion?
Hi Sallie – Either work! Quick-cooking oats offer a more delicate texture whereas old-fashioned oats offer a heartier one. :)
My family loved them . Very tasty and soft . Made them for our Christmas gathering. Will make again .
I measured out cookies in 6 grams. Rolled them in a ball then slightly flattened. Cooked for 15-17 minutes. Good stuff!
So glad you enjoyed the recipe!
Can you make the monster cookie without the peanut butter and add a different kind of nut?
Hi Pauline! You might be able to substitute another nut butter but I can’t say with certainty what the texture/results will be. Let me know if you give it a shot!
Hi Kelly. Have you ever made these with Splenda? Any adjustments?
Hi Jeanine – I’ve never made cookies with Splenda so unfortunately, I can’t weigh in on what the results would be. Let me know if you give it a shot!
I have used Splenda to help lessen the high sugar content. Use 1/2 to 2/3 cup Splenda because it tastes sweeter than sugar.
I’ve used several different types of recipes for Monster cookies. None of them compare to this amazing soft and chewy recipe!
Thank you. They’re amazing!
I’m so thrilled you enjoyed the recipe, Gerrilynn!
Love, love, love this recipe! Perfect every time! My grandbabies love them!!!
Thank you for this great recipe!!!
You are so welcome, Lori!
These turned out super delicious! I followed the recipe exactly and they were perfect! It did make a lot of dough, so I’m wondering if I could freeze some of it? Thanks for a great recipe!
This cookie dough freezes well, Rebekah. I recommend freezing it in balls/scoops so all you have to do is bake them off as needed.
These are simply wonderful! I’ve made them several times and they are a huge hit! I wouldn’t alter anything because they are perfect. Thank you for this wonderful recipe!
You are so welcome! I’m thrilled you’ve been enjoying the recipe!
Just made this recipe for 1st time…not impressed. Super crumply and just kind of blah. Do not bake beautifully. And before I get accused of using to many oats, I actually used 1 cup less. Do not recommend.
Hi Sarah! Using an entire 1 cup less of oats is going to greatly alter the recipe and lead to different results.
Great tasting cookies ! My family loved them . It was a first making them.
I’m so happy your family enjoyed the cookies, Angie!
These are delicious! Wondering if anyone has tried making the dough, forming it into balls and then freezing and baking them as needed? I do that with another recipe I have but not sure if it would work with this one?
Thanks, Amber! That would work great :)
“Before I get accused of not following the recipe, I need to let you know that I actually did not follow the recipe”.
Wondering if the type of peanut butter matters? Can you use a more natural one that only contains peanuts and salt?
Hi Gina! I personally haven’t used natural peanut butter in this recipe, but I know many other commenters have had success in doing so.
I accidentally put in 1 cup of butter rather than half a cup and figured I might as well double it because the reviews don’t typically lie! Well, these were great – I’m so surprised at their texture given they have no flour. They’re chewy yet light, almost like a peanut butter lattice cookie if such a thing existed. I’m currently on batch 75 million in the oven and counting. ;) I scoop approx 2 tbsp and bake for 12 minutes and they are golden on the edges and soft on the inside. A great recipe, I’m so glad to have found it!
Yay! I’m so glad you enjoyed the recipe, Jilliannie (despite having to bake 75 million batches )!
Super delicious and easy to make!
I’m so happy you enjoyed the recipe, Sarah!
Super easy and yummy, will definitely save this recipe!
I’m so glad you enjoyed the recipe, Jenny!
I have been trying different monster cookie recipes and this is by far THE BEST Recipe ever!!!! I will be making these forever !!! Thank you so much!! I used an ice cream scoop for size and got 46 cookies! (on recipe for 1 batch :) )
LOVE reading this, Michele! I’m thrilled you enjoyed the recipe!
The best recipe hands down. I get requests to make them all the time!
Woohoo! I’m so thrilled you’ve been enjoying the recipe!
I actually (accidentally) forgot to add the butter and it made them even better (in our opinion). Instead of crispy, we had soft, chewy cookies. Cookies that the neighbors loved too. So if you’re wanting a soft cookie, skip the butter—it works out great!
I’m glad they still worked out, Alisha! :)
I made these for my gluten free son who has celiac, he LOVES them! Actually the whole family does, I have used this recipe 2x now and they have turned out perfect. Thank you. Any suggestions on what I could substitute for the peanut butter for my daughter? She has a peanut and pea allergy.
Hi Amy! You might be able to substitute another nut butter but I can’t say with certainty what the texture/results will be. Let me know if you give it a shot!
Have you tried soy nut butter?
This is simply THE BEST monster cookie recipe! Please ignore anything less than 5 star ratings on this. Just like someone else has stated…undercooked, overcooked, whatever…this is it. This is the only recipe you will ever need!
Thank you, Jen! I’m so thrilled you’ve been enjoying the recipe!
Delicious! Perfectly chewy. Will make again.
I’m thrilled you enjoyed the recipe, Jennie!
Crazy simple fast .. cute to look at ! Delicious thanks
You are so welcome, Amy! I’m thrilled you enjoyed the recipe!
How long can I keep the raw cookie dough in the fridge before baking it?
Up to 3 days!
I loved this! My family are such big fans on monster cookies, and wanted to try a new recipe. My only notes are that my dough was so sticky! It made the kitchen messier, and got all in my nails. The other things is that is was always under baked, I put them in for as long as it needed but they would be crumbly and underbaked. You can never go to wrong with a monster cookie though. My family still adored them, and I will probably use this recipe again. Overall I loved them, besides those couple mishaps.
I’m so glad you enjoyed the recipe, Lacy!
So chewy and not overly sugary :)
I’m so happy you enjoyed the recipe, Annie!
I usually buy crunchy kroger natural PB, which has nothing but peanuts and maybe salt. Would it be best to buy the “regular”/non-natural type for this recipe?
Thanks!
Hi Maude! I personally haven’t used natural peanut butter in this recipe, but I know many other commenters have had success in doing so. Let me know if you give it a shot!
Absolutely delicious cookie! Quick and easy! Thanks!
You are so welcome, Kelly! I’m glad you enjoyed the recipe!
These were delicious!! But mine ended up baking into mounds/balls, and not flat and cookie- like. Any reason why?? I’m kind of bummed about it!
Hi Bex – There are several factors that may have attributed to your cookies not flattening out, such as how the heat circulated in your oven, your type of baking sheet and whether you used parchment paper or a Silpat. Perhaps next time you could flatten the dough slightly (after you’ve portioned it out)? Sorry!
Yes! Same! I followed everything, but my cookies did not flatten out at all after being baked.
So weird, Caine! I’ve never experienced that before with this recipe.
Great recipe! Nothing fancy, but these are SO good. Only tweak I made was subbing peanut butter chips for half of the chocolate chips. They turned out perfect, took them to a work potluck and they were a hit. Thanks so much!
You are so welcome, Emily! I’m thrilled you enjoyed the recipe!
These are the best monster cookies I’ve ever tasted and they’re so quick and easy to make.
I’m so thrilled you enjoyed the recipe, Deena!
Yum yum yummy!!!
Absolutely delicious! My kids who don’t even like peanut butter devoured these! Will definitely be our go-to cookie recipe from now on! Thank you for sharing!
WOWZA! I’m so glad you and your kiddos enjoyed the cookies, Ashley!
These turned out petfect
Can shortening be substituted for butter?
Absolutely!
This is my family’s go-to cookie recipe. Underbaked, overbaked, and baked just right, they are the perfect cookie!
Love reading this, Michelle! I’m so thrilled your family has been enjoying the recipe!
Just what I was looking for when I looked up monster cookies!! I’ve been craving these for a while now and I haven’t had them in years, so when I seen this recipe, I had to try it. These monster cookies bring me back to when I was a kid, they are so soft, and yummy! My kids loved them as well and the rest of the family. Thank you
Love reading this, Adeline! I’m so glad you enjoyed the recipe!
Love these cookies But I leave the choc.chips out & m&m’s because we’re not that big on chocolate…
I’m so glad you’ve been enjoying the recipe, Mary!
So good! My family LOVES them!
I’m so happy to read this, Sarah!
These are one of my favorite cookies to make! We found the recipe last fall and I’ve made them at least 20 times since then. Thank you for sharing!!!!
Love, love, LOVE reading this, Laura! I’m thrilled you’ve been enjoying the recipe!
Amazing cookies! I have tried several different recipes and by far-your recipe is the best. Thank you for sharing!
You are so welcome, Brenda! I’m thrilled you enjoyed the recipe!
Love these cookies! They have become my favorites. I used regular size m&ms and chocolate chips because that’s what I had and they were wonderful.
Amazing! I’m so glad you’ve been enjoying the cookies, Joanne!
Monster cookies are a new family favorite!
Woohoo! I’m so happy to read this, Ann!
Very easy one-bowl recipe. Delicious and chewy. For less sugar, I used Stevia replacing white sugar and 2/3 cup honey instead of brown sugar.
Awesome! I’m so glad you enjoyed the recipe, Jennie!
My husband declared these his new favorite cookies! I’m a high-altitude baker (7500ft.) but didn’t change a thing for these and they turned out perfectly. Also, I used all-natural peanut butter and because I didn’t have M&Ms on hand, I used one whole bag of semi-sweet chocolate chips. Highly recommend this recipe!!
Love, love, LOVE reading this, LC!
What size scoop did you use?
These cookies bring me back to my childhood. The school would make them and sell them on Friday’s. It was such a great end of the week treat!
Hi Lora! I use 3-tablespoon mounds of the dough, but any size works!
Great recipe, everyone’s favorite!
I’m so happy to read this, Dawn!
A friend of mine had requested Monster Cookies, I had never made them, so off to google I went, and found this recipe. I was not disappointed. It has now been printed and added to my recipe book. SO GOOD.
Woohoo! I’m so glad you enjoyed the recipe, Amanda!
Love your recipe…..just baked for my mother….she has dementia but remembers loving cookies….these cookies, thank you
You are so welcome, Kelly. I’m thrilled you and your mom enjoyed the cookies! :)
wonderful cookies!! Just made with my 7-year-old granddaughter and two of her neighbor friends. Should have taken pics… they had so much fun!
Love reading this, Jan!
I have baked the Monster Cookie recipe over and over, and it is a “hit” in our Family. I’ve found that using Quick Oatmeal and Mini M&M’s and Mini Chocolate Chips works best for mixing and keeping the cookies together. Have made double bathes and froze them, too. They disappear fast and are a ‘crowd pleaser’!
Love, love, LOVE reading this, Linda! I’m so thrilled your family has been enjoying the cookies!
THIS is my FAVORITE cookie recipe EVER! It is so fast, simple and easy and best of all TASTY!!! I can whip them up before a night shift and my nursing buddies and CNAs rave about them every time. I have shared this recipe LOTS of times and continue to do so! Thank you for sharing this treasure!
You are so welcome, Becky! I’m thrilled you’ve been enjoying (and sharing!) the recipe! :)
We enjoyed this. I was skeptical about the sugar amounts but the bland oats and peanut balanced it out. Wish there were baking tips, specifically how to know the cookies were done. I found they were perfect (underbaked) when the edges were light-medium golden brown and the centers still looked gooey between the oats. They definitely firm up a lot and darken after they cool. I used quick (1 minute) oats and a natural peanut butter that was runny and they still turned exactly like they’re pictured.
Thanks for your note, Cody! I’m thrilled you enjoyed the cookies!
Has anyone had any success with reducing the sugar a bit?
Great recipe! Instead of measuring 3 cups of peanut butter, I went with a regular size jar. Got many compliments on how soft and chewy they are! Size wise I was generous as I find the best monster cookies are big! Thank you – will make again!
You are so welcome, Micayla! I’m thrilled you enjoyed the recipe!
Very good recipe, soft and sweet. We added a box of instant vanilla pudding -sugar free, added it with the salt and baking soda.
Will definitely make again.
Excellent! I’m so glad you enjoyed the recipe, Barb!
Can I use regular size m&ms and regular size choc chips?
Absolutely, Kim!
Made these for my son’s birthday. Turned out awesome. Thanks for sharing!
You are so welcome, Marge! I’m thrilled you enjoyed the recipe!
So good, every time!
I’m thrilled you’ve been enjoying the recipe!
Yummy and easy
I have been making these monster cookies same recipie for over 20 years. I always use jif pb creamy. My kids and there friends loved them when they were young. Now my daughter who is now in her 40s makes them for her kids.
Love reading this, Cheryl!
These monster cookies were amazing! Instead of making 2-3 tablespoon balls of dough, I made them 1/3 cup. It made 12 cookies instead of 24 and the bake time was about 20 minutes, I would definitely recommend!
Woohoo! I’m so thrilled you enjoyed the recipe, Ayla!
Best monster cookie recipe in the whole wide world. Sorry not sorry.
I’m so thrilled you enjoyed the recipe! It’s one of my all-time faves, too!
I’ve been making these 4 ever!
Always great cookies!
But this time I made them with Biscoff Cookie Butter and Reese’s Pieces!!
Yup still a breakfast cookie!!
YUM! I’m so glad you’ve been enjoying the recipe, Guin!
I have made these cookies twice now. One of my co-workers said these are the best cookies I have ever made. So from now on these are the only cookies I make. Everybody loves them. Thank you.
LOVE reading this, Laura! I’m thrilled you and your co-workers have been enjoying the cookies!
Delicious!! The only thing I changed was rather than 1 cup M&M’s and 1 cup chocolate chips, I substituted with 1/2 cup each of M&M’s, dark chocolate chips, dried cranberries, and walnuts.
YUM! I’m so thrilled you enjoyed the recipe, Nancy!
Taste=4 stars
Look=2 stars
Instructions=5 stars
These tasted pretty good but it was so so so easy to make. She is amazing at explaining things
I’m glad you enjoyed the recipe, Dominique!
They turn out perfect every time! It’s the best monster cookie recipe I’ve used and the only one I use now!
Woohoo! I’m so thrilled you’ve been enjoying the recipe, Tory!
Nice thing too is that they are not only really yummy, they can be made gluten free (using the GF oatmeal & candies)! Thank you!
YES! You are so welcome, Jane! I’m glad you enjoyed the cookies :)
My husband loves peanut butter cookies so this is now a favorite. I mix up the chips, 1/2 cup mini M&Ms,1/2 peanut butter chips, 1/2 cup semi cho chips, 1/2 cup white chips. Then I add 1/2 cup macadamia nuts. I smash them down & add more of all the chip mix on top..
They turned out Great! Pretty & tastes great!
YUM! I’m so glad you’ve been enjoying the recipe, Christine!
These are the best!
I’m so glad you enjoyed the recipe, Mary Jo!
New family fave!! I use natural peanut butter and add sprinkles for the sprinkle-obsessed kiddos in my family! Huge hit – for both the littles and bigs!
Love, love, LOVE reading this, Cait! My boys are sprinkle-obsessed, too :)
I made a double batch of this recipe. The conversion table erroneously doubles and triples the salt, which completely RUINS the cookies.
if you make a double or triple batch, DO NOT DOUBLE THE SALT!!!
Hi Laurie – I just checked and doubling the recipe will double all ingredients correctly (including the salt). If you’re using kosher salt, doubling should work out great.
So, does this recipe call for course kosher salt? It just says salt on the ingredients.
Correct, Lys!
These are our favorites!
I’m so happy you’ve been enjoying the recipe, Laury!
How long would you bake in a sheet pan?
Hi Kelly! I have a recipe for Monster Cookie Bars. Here’s the link to the recipe: https://www.justataste.com/monster-cookie-bars-recipe/ :)
One of our family’s very favorite cookie recipes! My kids’ friends love them as well. One friend said she had dreamed about the cookies after she had one that my teen shared with her. :-D
LOVE this! I’m so thrilled your family has been enjoying (and sharing!) the cookies, Jaena.
These cookies are amazing!!! I doubled the recipe and used white chocolate chips and added 2 cups of chopped black walnuts and a cup of raisins….next time I’ll add more raisins. The sky’s the limit on what you can add to these Monster Cookies!!
Yessss! I’m so thrilled you enjoyed the recipe, Julie!
I made these today and they tasted good but where flat and chewy.. could I add an additional minute or 2
Hi Kendra – It’s hard to say what might cause flat cookies. Is your baking soda fresh?
Adding raisins are wonderful just 2 boxes and a Lil less oats. For chewier cookies a Lil less time on the oven
YUM! I’m so glad you enjoyed the recipe, Tamy!
Made these and the Monster bars today and my family was in heaven! Warm bars with vanilla ice cream on top was a hit!
YESSSSS! I’m so thrilled you and your family enjoyed the recipes, Ronnel!
Are you able to prep the dough a day in advance and refrigerate?
Hi Anne! I have never tried refrigerating and then baking the dough, so I cannot say with 100 percent certainty how they will turn out. They will bake up no problem, but it’s more a question of consistency. Let me know if you give it a shot!
I just baked some of these right out of the fridge and they baked just fine. I molded them into haystack type blobs and they didn’t flatten but the came out fine nonetheless.
Excellent! I’m so glad you enjoyed the recipe, Barbara!
I refrigerated the dough 24 hours in advance— it’s harder to scoop the cookies into the right size and shape, but the end result is identical :)
Thanks so much for your note, Bek! I’m thrilled you enjoyed the recipe!
Can I use regular size M&Ms chocolate chips instead of minis?
Absolutely!
The BEST monster cookie recipe around! They are absolutely delicious!!
YESSSSS! I’m so thrilled you enjoyed the recipe, Holly!
Kelly, I found your recipe two years ago and this is my favorite recipe of all time. Thank you for sharing this with all of us. I sometimes add a bit more chocolate chips/M&Ms if I’m feeling indulgent. Also, my butter is almost always frozen when I get a craving for these so I melt it in the microwave and so they tend to be more chewy, but I kind of like them better that way.
I’m so thrilled you’ve been enjoying the recipe for so long! It’s one of my family’s all-time faves :)
No flour?!
Correct, Kayla, no flour! :)
So good we made some with the family and had so much fun
I’m so glad you enjoyed the recipe, Rosie!
My family loves these cookies! Sometimes I’ll make mini-monster cookies, for smaller appetites. Of course, I adjust the bake time. Thinking about trying it with almond butter for my grandson with a peanut allergy.
I’m thrilled your family loves the cookies, Diane! Let me know if you make an almond butter version!
Love these cookies! I usually don’t like to bake cookies but these are so easy.
I’m so glad you enjoyed the recipe, Mel!
Can you subsitute almond butter for peanut butter? We have a peanut allergy in the family :(
Hi there! I personally haven’t used almond butter in this recipe, but I know other commenters have had success in doing so. Let me know if you give it a shot!
Perfect. Just like what I remember as a kid growing up, going to grandparents house! These cookies bring back so many great memories! I def prefer using chunky peanut butter for even more texture. Thanks for the great recipe and bringing back so many great memories!
This is what I love to read, Aaron! I’m so thrilled you enjoyed the recipe!
Omg, my girlfriends daughter made these and they are so delicious! Can’t wait to make them myself!
I’m so happy you enjoyed the cookies, Robin!
Thank you!!!
This IS the recipe my grandma Betty made! It’s a nice nostalgia of my childhood!
Love reading this! I’m thrilled you enjoyed the recipe!
These are delicious and easy to make! My bf loves them and made them himself for the first time ever baking cookies alone
Love, love, LOVE reading this, Lauryn!
Made it as posted. They were perfect! Best monster cookies ever!!!
Woohoo! I’m thrilled you enjoyed the recipe, Sarah!
These are perfect! Crispy on the outside, chewy in the middle! We froze a bunch to thaw overnight for kids breakfasts! Highly recommend.
I’m so happy you enjoyed the recipe!
Cookie perfection. I love this recipe. I didn’t have to change anything.
Best cookies ever and the recipe is easy to follow. They turn out great every time!
I’m thrilled you’ve been enjoying the recipe, Laurie!
My favorite and everybody that tastes them as well.
I’m so happy to read this, Stacy!
These are so chewy and delicious! I was about a half cup short on the oats so I used flour to get to the right amount and they still turned out well!
I’m so glad you enjoyed the cookies, Sam!
Just made these. Whole family loves them. They are a big hit. Thanks so much for sharing!
You are so welcome, Melody! I’m thrilled your family enjoyed the cookies!
Make these all the time. The crew at work loves them!
I’m so happy you’ve been enjoying the recipe, Charlotte!
Fantastic cookies!! Taste like baked no-bake cookies!
I’m so glad you enjoyed the recipe, Sharon!
Fantastic! I just made a 1/3 recipe batch so to have some for Santa. They are very chewy and delicious. Bring on the milk.
Love this! I’m so glad you enjoyed the cookies, Mark!
They were gone within an hour of coming out of the oven!
Woohoo! This is what I love to read, Nancy!
EXCELLENT recipe! So delicious & chewy with a perfect amount of crunch. Thank you for the tip on under-baking just a bit–makes them perfect!
You are so welcome, John! I’m thrilled you enjoyed the cookies!
These are delicious! Even the ones that fell apart because I replaced some of the oatmeal with shredded coconut. I added more oatmeal and they looked much better. I doubled the recipe, made cookies with a heaping teaspoon instead of the 2 – 3 tablespoons and will have enough for the whole neighborhood!
Love it! I’m so glad you enjoyed the recipe, Laurie!
Very good recipe. I even copied it down to not lose it. I want to put raisins, cranberries, and coconut in the next batch.
Yummy!
YUM! I’m so thrilled you enjoyed the recipe, Lisa!
Delish! Sent them to my son at college and he and his buddies loved them.
Going to try and make a vegan version for a friend for Christmas.
I saw in the comments that someone used applesauce instead of eggs successfully. Will use dark chocolate chips. Fingers crossed the butter substitute works. I didn’t read all the comments. Did anyone tell you if they made a vegan version?
Hi Jennifer! I haven’t made a vegan version of these cookies so I can’t say with certainty what the results would be. Let me know if you give it a shot!
I have a dairy allergy and have successfully made these with a vegan butter substitute. They are delicious.
Thanks so much for your note, Judy!
Awesome recipe! Crispy and chewy! Perfect, love these! Will make these again. And my Christmas gang are going to love these as well!
Woohoo! I’m so thrilled you enjoyed the recipe, Patsy!
Came out great. Nice and chewy. Got 48 cookies with a large cookie scoop. I used holiday M&Ms and skipped the chocolate chips. Thanks for recipe!
Love this! I’m so thrilled you enjoyed the recipe, Kelly!
Thought I would try these after reading the reviews. I used a large cookie scoop and got 56 nice sized cookies. They weren’t what I was hoping for, looking for a more chewy cookie, plus these were more like the oatmeal cookies I make except without peanut butter. One child liked them and the other didn’t because they didn’t like the dominating peanut butter flavor in them. Thank for sharing though.
Thanks for your note, Cindi!
Wow. I love it. My daughters loved it. A great recipe for Saturday morning
I’m so happy to read this, Rachel!
My family LOVES these cookies. They are great for taking to wrestling meets or just enjoying. The oats give it a substantial feeling. My kids try to convince me they can be eaten for breakfast because of the peanut butter and oats. These are absolutely delicious.
Haha! My husband would agree! I’m so thrilled your family has been enjoying the cookies, Angel :)
Are these gluten free? Or have a very low amount of gluten?
Hi Maya – All of the ingredients for this recipe are naturally gluten-free. However, to be on the safe side, I recommend buying products that specifically say “gluten-free” so you know there hasn’t been any cross-contamination.
Love this cookie! Found it this year and can’t wait to make them with just red and green chips for Christmas. Thanks for sharing.
You are so welcome, Dawn! Love the idea of making a Christmas version!
I have made these for years….realized that your recipe doesn’t have 1 1/2 tablespoons of corn syrup and mine h as less choc chips…..I mistakenly left out the baking soda and the salt, and believe it or not, I think they taste better without, however, don’t know how they will keep. I am making them for my grand daughter, who is now 26 years old and still loves them. She also makes them herself now, but has to work a lot and do housework, etc., so thought I would make them for her again this Christmas.
Love this, Linda! I’m so glad you’ve been enjoying the recipe :)
I have made these several times now. I like to play with suing peanuts butter M&Ms, adding white chocolate or Reeses chips. Everyone raves about them.
I’m so glad you’ve been enjoying the recipe, Lori!
Excellent recipe. I made a double batch and put half peanut chips and half chocolate chips. Nice texture and flavor.
Awesome! I’m so glad you enjoyed the recipe, Angela!
Delicious cookies! Doubling the recipe will make the mixer overfill so you may just want to mix up one recipe at a time.
Thanks for your note, Tammy! I’m thrilled you enjoyed the recipe!
Wish I would have read your post first! My mixer was overfilled and started overheating. Did you make any changes to the amount of oatmeal you put in the recipe?
how many cookies does this recipe make, been making these for yrs. & their my no. 1 cookie
Hi Grace! It depends on the size you scoop, but if you scoop 2-to 3-tablespoon mounds of dough you’ll end up with about 24 cookies.
My grandma used to make these for me when I was a young kid. I always thought they were the best cookies ever. I have used this recipe for years and now my kids always ask me to make them for them every year for Thanksgiving and Christmas. I am sure they will be asking me for the recipe so they can make them eventually for their kids.
Love, love, love reading this, Bill! I’m thrilled your family has been enjoying this recipe for so many years. :)
These are the best! I’m Also new here So Hello, I will also discover your other good recipe because I’m not worried one bit about messing up because this one was a piece of cake, Matter Fact I’m going to make me a piece of cake following your recipe.
Thank You!
I’m so glad you enjoyed the recipe, Zaniyah!
This recipe is the best, my entire family loves them! I made one addition, chopped pecans. Yum!
YUM! I’m so thrilled your family enjoyed the cookies, Melinda!
Didn’t work for me. Cookies were flat and sticky. So sticky that they stuck to the parchment paper. They crumble apart when you pick them up. So disappointed. Baked 15 minutes at 350 and then removed them.
Hi Amber – I’m sorry you didn’t enjoy the recipe. It’s hard to say what might cause flat cookies. Is your baking soda fresh?
Love this recipe! I made them for Halloween treats for work, they were a big hit. I will be making them again.
Woohoo! I’m thrilled you enjoyed the recipe, Tammy!
LOVED making these cookies. They’re easy and so delicious! Everyone’s asking for the recipe
Yay! I’m thrilled you enjoyed the recipe, Crystal!
I made the cookies according to the “1x” recipe which said 24 cookies. I made the cookies quite large, and yet i ended up with FORTY cookies. They are delicious but beware of the proportions
Excellent. Everyone who tries these loves them and asks for the recipe.
I’m so glad you’ve been enjoying the recipe, Talitha!
I have made these 4 times now. This is by far the best monster cookie recipe I’ve come across. At this point, I’ve printed it out and keep it in my recipe box. My friends and family are pretty obsessed with them! Thanks for sharing!
Love reading this, Jenna! I’m thrilled you (and your friends and family!) have been enjoying the recipe.
HI! I’ve got a question. No flour? Or is that a mistake? Thanks for answering!
No flour! :)
So yummy! I’ll be saving this one!
I’m so glad you enjoyed the recipe, Kelly!
I have made these and you can add just about anything you want and they have no flour which is a good thing. You have some very good recipes.
I’m thrilled you’ve been enjoying Just a Taste, Kathryn!
Mine definitely went flat. Not sure what I did wrong. I used no name smooth peanut butter.
Hi Kelsey – It’s hard to say what might cause flat cookies. Is your baking soda fresh?
For a peanut allergy what could you substitute peanut butter with.
Hi Sherry! You might be able to substitute another nut butter but I can’t say with certainty what the texture/results will be. Let me know if you give it a shot!
Hi do you know if I add anything or take anything away for high altitude?
Hi Amy – I’m not a high-altitude baker so I’m not certain what adjustments (if any) would need to be made. Please let me know if you give the recipe a shot!
Hi there, I desperately am craving these. I only have natural peanut butter. Should I reduce the butter? Any ideas on how I could adjust so the natural peanut butter won’t negatively impact the result?
Hi Ellie! It may work if you drain the excess oil from the top of the peanut butter!
Absolutely the best cookies I ever made.Everyone LOVED them.My new cookie recipe.
I made them with the natural peanut butter and they worked perfectly. They were absolutely amazing. I did 2TBSP sized cookies, for 15 mins and got 35 cookies. They are amazingly soft and chewy thank you so much for the recipe!!!
You are so welcome, Ellie! I’m thrilled you enjoyed the cookies!
I was very frustated with this recipe.
First it made double the amount as indicated.
The cookies are super soft and fall apart very easily.
I’m sorry you didn’t enjoy the recipe.
I made these monster cookies. Super easy and delicious!
I’m thrilled you enjoyed the recipe, Brenda!
We made these today and added a few peanut butter m&m’s. So dang good! Great recipe! Thanks so much for sharing!!
You are so welcome, Peg! I’m thrilled you enjoyed the recipe!
If the dough is too gooey, as in…no way could I hand-roll into a ball…. Do you suggest more oats? TBH, my 4 year old granddaughter “helped” so I’m not 100% certain on my ratios… ♀️
Hi Marilynn! This dough will be too wet to roll into balls. You’ll want to use a scoop or two spoons.
Okay not that great – very peanut buttery – made more than I thought
I’m sorry you didn’t enjoy the recipe.
I made them October 9, 21. Love the recipe, my daughter in law has celiac disease and she can’t have wheat so these are a great delicious treat for her, and the kids love them.
Yay! I’m so glad your family enjoyed the cookies, Mary!
These cookies were so good! My husband took one bite and said WOW. Thanks for sharing this recipe!
You are so welcome, Laura!
Way too many chocolate chips and mini M&M’s. There isn’t enough dough to hold it together and they crumbled when I scooped then onto the cookie sheet. I would try again but with half as many chocolate chips & mini M&M’s.
I followed the recipe exactly.
Hi Cathy – I’m sorry you didn’t enjoy the recipe. I’ve never experienced there being too many chocolate chips or M&Ms.
Kathy, there is a small discrepancy on the x2 butter calculation. You need 2 sticks, not 1. Might explain your issue. Try again!
Absolutely the best cookies I ever made.Everyone LOVED them.My new cookie recipe.
Woohoo! I’m so thrilled you enjoyed the recipe, Sherry!
Best monster cookie recipe
I’m thrilled you enjoyed the cookies, Jeannine!
The best road trip coolies, college care package cookies or feeding a crowd cookies! I have been baking these for 30 years.
YESSSS!
Best monster cookie recipe I have found! Had to use regular size peanut butter M&Ms because someone ate all my plain ones without telling me. Took them to work and got TONS of compliments. Thanks Kelly!
You are so welcome, Becki! I’m thrilled you are your coworkers enjoyed the cookies!
Hi Kelly,
I made this recipe last night, although my cookies did not look as pretty as yours, it sure tasted really delicious. Thank you for sharing all your recipes.
You are so welcome, Marietjie! I’m thrilled you enjoyed the cookies :)
What a treat it is to come upon your recipe! I’m looking forward to sending a tin of these to my nephew who has celiac disease. I don’t have time for a cookie flop….so…what brand of and texture (creamy/chunky) of peanut butter do you use? A million thanks!
Hi Aunt Tracy! I use Skippy creamy peanut butter, but any brand will work (as long as it isn’t the natural type, as those tend to be too oily). Enjoy!
Some of the best cookies I’ve ever made – my friends absolutely loved them!
Thrilled to read that, Suhita!
The BEST monster cookie recipe I have ever made. I have made it several times and I really like just mixing it up by hand. I did cut the sugar back to 3/4 of each the second time I made them and have continued to do so. Teenagers and husband approved and they are now our go to cookie.
Thanks, Teresa!
I want to add peanut butter to this monster cookie! How much would you recommend adding ? These look so goooood
Hi Renee – This recipe calls for 1 1/2 cups peanut butter.
Delish! Our new favorite cookie!!
Yay! I’m so glad you enjoyed the recipe, Jane!
Great cookie! I used a heaping 1/2 cup each of mini chocolate chips, mini m&ms, white chocolate chips and Reese’s pieces.
YUM!
I tried the Monster Cookie recipe and it was easy and delicious. I think next time I will try it with raisins. I love oatmeal raisin cookies.
I’m thrilled you enjoyed the recipe!
I have made many monster cookie recipes. This one is by far the best. I wanted them a little crunchy so I baked them for about 15 min. They were perfect.
WOW! I’m so thrilled you enjoyed the recipe!
LITERALLY CRACK! I LOVE THESE! They’re the perfect cookie! I also added Reeses Pieces, peanut butter chips, and white chocolate chips! SO SO SO GOOD!
YESSSS! I’m so glad you enjoyed the recipe, Jace!
Loves these cookies! I make them with Reese’s Pieces and they are amazing! Best monster cookies I’ve ever made.
Amazing! I’m so thrilled to read this, Ashley!
Granddaughter loves to make these. My son who hates chocolate loves these cookies.
Amazing!
These cookies are so delicious. I am usually not a huge peanut butter cookie fan, but I had been searching for a good oatmeal cookie recipe. I tried this one, and I’ve eaten so many of the batch! The kids and hubby approve as well :). I cooked them for 11 minutes to make sure they would still be chewy, and on day 3 they are still chewy. So good dipped in milk too, mmmm. I only save recipes I really love and would love to bake again, and this one is definitely being saved! Thanks a million.
You are so welcome, Krissi! I’m thrilled your family enjoyed the cookies!
Awesome and easy everyone loves them. I make them for my family and grandchildren
I’m so thrilled your family has been enjoying the recipe, Phillis!
Easy and delicious
I’m so glad you enjoyed the recipe, Jim!
Looking forward to trying this recipe!! Do you use milk chocolate or semi-sweet chocolate chips?
Hi there! I prefer semi-sweet chocolate chips but milk chocolate would be delicious, too!
These are DANGEROUSLY good! Hubby had to take them away from me! Great easy recipe, kids loved making them and seeing all the goodies go into them. The only thing we changed was instead of a cup of mini chocolate chips we did 1/2 cup and 1/2 cup mini butterscotch chips AND OHMERGOD!!! These are going to be a constant request in our household! Baked for 12 mins and we got 39 decent sized cookies!
LOVE IT
YESSSS! Love reading this! I’m thrilled your family enjoyed the recipe :)
My sister and I made these cookies today and they are perfect! We didn’t have quite enough oats, we added raisins for fun, and used regular size M&Ms and chocolate chips. We definitely will make these again, but hopefully with the right amount of oats!
Awesome! I’m so thrilled you and your sister enjoyed the cookies, Addie!
This is a keeper recipe!!
Yay! I’m so thrilled you enjoyed the cookies, Deb!
YUM!! We had an office birthday party for a co-worker & she requested Monster Cookies for her treat. I had a recipe that I used before, but I was not really happy with it so I searched for a different recipe and came across this one. I was a bit skeptical about making a flourless cookie, but after reading the 5 star reviews your recipe received, I had to give it a try. It did not disappoint! These are delicious, moist & chewy. This recipe is definitely going into my cookie recipe collection. Thank you so much for sharing it with us!
Yay! You are so welcome! I’m thrilled you enjoyed the recipe :)
Our go to now! Fantastic just as written.
Amazing! I’m so thrilled you’ve been enjoying the recipe, Tricia!
Awesome recipe. Made a triple batch today for my Mom’s 80th birthday party. We have an industrial size Hobart mixer. I would never try to make that much with a table top or hand mixer. To thick of batter. I didn’t buy creamy peanut butter but chopped up a total amount of 1.5 cups of peanuts and added to the mix. I would also not use 3 cups of each chips and M & M’s. Had leftovers in the bottom of the mixer. (Could have been because of the peanuts added). I will definitely save this recipe for the future!! Thank you
So glad you enjoyed the recipe, Mary!
I’m looking for a Monster Cookie without peanut butter (for allergy purposes). Can you eliminate the peanut butter in this recipe? Maybe substitute something else? Thanx in advance!
Hi Ereka! You may be able to substitute another nut butter but I can’t say with certainty how it might affect the texture/results. Let me know if you give it a shot!
Ereka, I have made this with sunflower butter and Enjoy Life chocolate chips. It really good!
There’s a little girl at church who has a bunch of allergies, nuts being on that list so I tried to make a version she could have.
The cookies are a bit crumblier and spread out much further than peanut butter would, but they’re still delicious.
We call them Hazel Cookies after the name of the girl at church.
Love this! Thanks so much for sharing, Arianna!
My favorite cookie!! First had them at my niece’s house. Her daughter bakes them for fundraisers at their church. Said there is always a high demand for the cookies. I can understand why. Yum!
Amazing! I’m thrilled you’ve been enjoying the recipe, Faye!
Awesome cookies! I made these as a GF alternative for a Monster Cookie bike ride and they were a hit!
Woohoo! I’m thrilled you enjoyed the recipe, Julie!
Super yummy and easy to make! (I’m in fifth grade.) Definitely making these for my grandparents! Thank you so much for this recipe. For that soft and chewiness, how long do you cook them for? I did 11 mins.
That’s so awesome, Pietra! I’m thrilled you enjoyed the recipe! The best way to guarantee your cookies are chewy and not too crispy is to underbake them slightly (start checking them around the 9-minute mark) then remove them from the oven and allow them to cool for 5 to 10 minutes on the baking sheet.
Just awesome!!! Love these cookies. I’ve made them a number of times now and they always turn out great. Easy to make. Love that it’s just one bowl. I’ve started swapping raisins for the chocolate chips.
Woohoo! Love reading this, Laura! I’m thrilled you’ve been enjoying the recipe :)
I think this recipe will become a 25 year classic in our family one day
LOVE this! I’m so thrilled you enjoyed the recipe, Brayden!
Delicious!! I swapped out peanut butter for almond butter due to an allergy, and it’s fantastic. Would probably be amazing with cashew butter too.
Monster cookies are such a great recipe to just chuck whatever leftover baking goodies you have in – nuts, chocolate chips, whatever. It’ll always taste amazing.
Adding this recipe to my recipe box. Love it!
So glad you enjoyed it!
This is the best monster cookie recipe on the Internet. I have to make them and send them home with my nephew when he comes.
WOWZA! Thank you so much, Stacey! I’m thrilled you enjoyed the recipe :)
Amazing cookies, they turned out delicious! I always underbake to assure they’re soft and chewy :)
YESSSSS! I’m so thrilled you enjoyed the recipe, Vee!
HUGE hit in our house! Have already passed along the link to my mom, MIL and sister.
Woohoo! I’m so happy to read this, Heather!
I love how easy this recipe is and my kids LOVE these cookies.
Woohoo! Love reading this, Jenny!
Oh my gosh! What was I thinking. Please give the comment by “Karla” 5 stars!!!!! Thanks
Thanks so much, Karla!
Wow! Great Cookies. Hardy, Healthy, Soft and Chewy These cookies are going to be made a lot this summer. PERFECT!
I’m so glad you enjoyed the recipe, Karla!
These were an instant hit with friends, family, and co-workers. Everyone asks for the recipe! Any treat that can please ALL those groups definitely deserves 5 stars. Thanks for sharing!
You are so welcome, Tracy! I’m thrilled everyone has been enjoying the cookies!
Thank you for having this recipe. I couldn’t find the one I have. My family loves these delicious healthy homemade cookies. Can’t wait to make them tomorrow. It’s a family stalle for camp and elk hunting.
Wonderfully filling gluten free cookie!!
Quick and easy to make and bake.
I make 6 cookies at a time and put the rest of the batter in an air tight container so that I can have fresh, hot cookies every day.
I like to under bake them so they are nice and gooey
My daughter is allergic to eggs, so we use 3/4 cup applesauce instead of eggs, and they turn out so yummy!
Thanks for sharing that substitution, Meredith!
Hello,
We raise ducks, and most folks allergic to chicken eggs can eat duck eggs. The duck eggs are wonderful for baking, and make a richer dessert. Just a thought!
Made a double batch and they came out perfect! I have celiac so finding a tasty gf cookie can be difficult and this ones a keeper. Thank you!
You are so welcome, Shelly! I’m thrilled you enjoyed the cookies!
I’ve been looking for a great monster cookie recipe since falling in love with the ones from a local bakery- this is it!! Perfection.
I’m so thrilled to read that, Amanda!
My granddaughter has Celiac Disease. I’m looking for a great tasting cookie she is able to eat and taste great. Can I use gluten free Oats or will they just fall apart?
That should work! :)
Just made these to give as a birthday gift. They are easy to make and super yummy!! Thank you!
You are so welcome, Rhonda! I’m thrilled you enjoyed the recipe!
This is my go-to cookie recipe. I’ve made them probably a dozen times and they come out perfect every time! Crowd favorite, easy and delish
Yay! I’m so thrilled you’ve been enjoying the recipe, Rachel!
Great recipe! I like to add peanuts and raisins too
YUM! I’m so glad you’ve been enjoying the recipe, Eva!
Easy and yummy. Makes good batch that will be great in lunches.
I’m so glad you enjoyed the cookies, Monique!
Best cookie recipe!
I’m thrilled you enjoyed the recipe, Melissa!
Yum!
Very tasty and BIG!!!
I’m so thrilled you enjoyed the recipe, Sally!
I love this recipe!!!! I get compliments on it every time. I leave out the m&m’s and double the chocolate chips (I use nestle dark chocolate morsels) when I make them for myself. My kids love the traditional recipe with the m&m’s.
Love reading this, Katrina! I’m so thrilled you’ve been enjoying the recipe!
These monster cookies are the best. I used both kinds of oatmeal as I had some of both. Absolutely loved these monster cookies! No googly eyes in mine though!
ha! I’m so thrilled you enjoyed the recipe, Mary!
Hello! I am trying right now to bake these. But I’m having trouble with first step. I would like to make x2, but the recipe says 1 stick of butter (for x1-x3 quantities) but the measurements in cups vary . My mixer has been working for almost 40 minutes with no creaming happening. Am I doing something wrong? Please help! Thank you.
Hi Sylvie – Thanks for catching that! Please follow the cup measurements. :)
Great cookies! As cookie dough without the eggs is so delicious chilled too!
YESSSS! I’m so thrilled you enjoyed the recipe, Clarissa!
Turned out very good. Made several times now trying to use up oatmeal.
I’m so thrilled you’ve been enjoying the recipe, Jerry!
Hi! I just made your recipe last night for my friends, but I’m seeing some of them in a week. Will the cookies last a week or should I make another batch next week? Please let me know, thank you!
Also, I was skeptical initially because this recipe uses no flour and a lot of oats, but they turned out perfectly!
Best,
Philip
I’m so glad you enjoyed the recipe, Philip! And the cookies will keep for up to a week when stored at room temp in an airtight container. :)
I made this recipe a while back and searched it up to make them again. They are so delicious and Great for me being gluten-free. I just can’t remember if quick oats or rolled oats was yummier. I want them soft and chewy, would the kind of oat matter?
Hi Jessica! Quick-cooking oats offer a more delicate texture whereas old-fashioned oats offer a heartier one. :)
My husband has had many, many cookies in his life and says these are “the best cookies he’s ever had.” I don’t even typically love monster cookies and I love these!!! Do you have nutrition information for these? Thanks for the recipe!
Woohoo! Love reading this, Megan! You can find the estimated nutritional info by clicking on the purple button below the recipe that says ESTIMATED NUTRITION INFORMATION. :)
I had to search for this recipe because Mom tossed it when she pared down her recipe collection. This is the one I remember! No flour. Which also really helps for anyone on FODMAP or gluten free. Obviously it’s not recommended, but when are amazing and delicious cookies ever?!? Thank you, this is the recipe i was searching for! As noted in other comments, be careful, these are MASSIVELY addictive… so yumm!
Woohoo! I’m so thrilled you enjoyed the recipe, JoAnne!
These taste much more like a granola bar than a cookie. They’re not bad. But not what I was expecting
Interesting! I’ve never thought these tasted like a granola bar, Rosie. Did you follow the recipe as written?
Hi! What kind of mini chocolate chips? Semi sweet?
Hi Kelsey! Any variety will work but I prefer semi-sweet. :)
Easy. Delicious. The perfect recipe you can’t go wrong. I went out of my way to leave a 5-star review because these are so worth it! I can’t tell you how many people have asked me for this recipe, it’s soooo good!!
Thank you so much for leaving a review, Sarah! I’m thrilled you’ve been enjoying the recipe!
Warning. Making these cookies will ruin your week. But only if you’re on a diet. I am unable to stop eating these things and I am trying so hard- I’ve put them I the freezer but that just makes them better
11/10 recipe will make again
haha, love this! I’m so thrilled that you’re enjoying the cookies, Amy!
I made these and brought them to work for people to try and people loved them. People were very surprised that it didn’t have flour in them. These cookies will be a go to recipe, very simple and quick to make.
I’m so thrilled to read this, TJ!
Was just “gifted” some….YUMMY…….went searching for the recipe!
Woohoo! Love reading this!
Best recipe ever!
I’m so thrilled you enjoyed the cookies, Tracy!
love, love, love these cookies. the first time i only had regular chips. now it’s only the mini. soooooooo much easier to handle and they melt great. i used a baller. about 1/2 way through i flattened them a bit. so yummy and great for people that are gluten free. oh, sometimes i add coconut. sometimes nuts. can’t go wrong…
Awesome! I’m so thrilled you’ve been enjoying the recipe!
I have made these before and everyone LOVED them!! This recipes makes so many cookies, which is usually great but wondering if I can make a batch and bake half now and freeze half of the dough for later?
Sure, Courtney! I recommend freezing the cookie dough in balls/scoops so all you have to do is bake it off as needed. I’m so glad you’ve been enjoying the recipe :)
These cookies are incredibly delicious and super easy& quick to make! I did not include chocolate chips in mine and used an entire 10 oz pkg of mini m&ms instead. Despite the fact that I didn’t have the 2 full cups of candy/chocolate in the mix (my only modification), they are sooooooo good! I prefer a chewy cookie and this recipe absolutely delivers (note: I did follow the timing of the bake & the cooling tip to achieve this). Perfection!
Awesome! I’m so thrilled you enjoyed the recipe, Shannon!
It’s my go-to recipe for sure! Just made again today, since the hubby ran out of the 2 batches I made for Christmas! A definite family favorite.
Woohoo! I’m so thrilled your family has been enjoying the recipe, Donna!
I like the recipe a lot because it doesn’t have flour. I think next time I may cut the sugar a bit. Delicious overall!
I’m so glad you enjoyed the recipe, Jess!
These are delicious! I followed your advice and slightly under bake them so they stay chewy! I love sharing this recipe because it’s so easy. I use a small cookie scoop and can get 5 dozen out of the recipe.
I’m so thrilled you’ve been enjoying the recipe, Jessica! It’s one of my all-time favorites!
My new favorite cookie recipe.
I’m so glad you enjoyed the recipe, Heidi!
These monster cookies are a favorite at our house and travel well in college care packages!
Love reading this, Kelly! I’m so glad you’ve been enjoying the recipe!
Thanks, but that nutritional value bar doesn’t tell you, weight , in grams or ounces, or size of the average cookie so it doesn’t help very much. But thanks for answering anyway. I was just curious since I’m sorta watching my calories.
Sorry!
Absolutely delicious! We added a cup of mini Reece’s peanut but cups and pieces…so good!
YESSSSS! So thrilled you enjoyed the recipe, Sarah!
Just curious but approx how many calories in a cookie? Of course I couldn’t tell eat just one. They were awesome!
Hi Mike! You can find the estimated nutritional info by clicking on the purple button below the recipe that says ESTIMATED NUTRITION INFORMATION. :)
Would it be ok to replace sugar with maple syrup?
Hi Lan – Using maple syrup will result in a completely different taste/texture.
They were so delicious my family loved them. Definitely recommend this recipe. I made these and I’m 9 years old. so easy to make and they are so good.
That’s so awesome, Grayson! I’m thrilled you enjoyed the recipe!
Our absolute favorite at our house!!! Thank you!
I’m so thrilled to read this, Christina!
yield?
Hi there! The recipe yields about 24 cookies, it all just depends on how big you make your cookies.
I’m not sure what happened to my cookies but the m&m’s melted and the cookies were big and flat. I read through the recipe again and did everything right so is this a high altitude problem as I’m in Colorado. They tasted fine just looked like 6″ flat oatmeal cookies. :(
I’m not a pro at high-altitude baking so I can’t say with certainty what happened to your cookies, Michele. Sorry I can’t be of more help!
How would you go about storing these to bake for later??
Hi Dara – I recommend freezing the cookie dough in balls/scoops so all you have to do is bake it off as needed. :)
16mins on pampered chef stoneware
Flattened nicely
Light golden colour
13mins on parchment on metal baking sheet.
Cool completely, remove and soooooo chewy and yummy
I’m thrilled you enjoyed the recipe, Lori!
Crowd favorite!
Made these this past weekend for the first time! Let’s just say, they didn’t last very long!
The crunchy, yes smooth texture and delicious taste has me hooked!
Easy to make, even easier to eat!
I’m so thrilled to read this!
No flour? I want to bake these, but I’ve gone over the recipe 4 times and is it correct that there is no flour in these cookies?
Correct, no flour! :)
These are so yummy! Definitely saving as one of my go-to cookies! :) Just have to say the yield is definitely more than 24 for me. I used a standard cookie scoop and had about 50-60 cookies! Would definitely look to half this recipe in the future for a smaller crowd!
I’m so thrilled you enjoyed the recipe, Stephanie!
Have you edited this recipe in the past year? This used to be my favorite recipe but I stopped making them for a while. I’ve started again and it seems to be different than I’m remembering. They no longer flatten out in the oven. I have to press them all down into the shape of a cookie. I also thought there used to be more butter?
Hi Jaime! This is still the original recipe that my family has been using for over 25 years. :) There are several factors that may have attributed to your cookies not flattening out, such as how the heat circulated in your oven, your type of baking sheet and whether you used parchment paper or a Silpat. Perhaps next time you could flatten the dough slightly (after you’ve portioned it out)?
Finally found the one.
Woohoo!
We love these cookies! Just put a batch in the oven for my son’s 15th birthday party. Requested by him!
I’m so thrilled to read this, Sarah! And happy birthday to your son!
These cookies are the best! I scoop them out and put the dough in the freezer so I can bake a few fresh whenever I want. So many people have asked me for this recipe. I made these for a graduation party and they were a hit!
Love reading this, Sue! I’m so glad you’ve been enjoying (and sharing!) the recipe. :)
This recipe is delicious! I prefer to keep the batter in the fridge and bake them as we want them because we love them fresh. How long can I store the batter in the fridge? Thanks!
Hi Kristen! I recommend freezing the cookie dough in balls/scoops so all you have to do is bake it off as needed. :)
Have you tried this recipe with natural peanut butter? If so what were the results?
Natural peanut butter works!
Love these!!! Great recipe! Easy to make as well as to eat.
I’m so glad you enjoyed the recipe, Judy!
Wow! These are amazing. Thank you!!
I’m so glad you enjoyed the recipe, Megan!
My first time making these after having a friend’s mom baking these when growing up. They are perfect. Thank you!
Yay! I’m so happy to read this, Greg!
Been making this cookie for more years than I can remember. Only difference in the normal recipe I use and this one is the lack of Karo Syrup. The original recipe was 4 times this batch and took forever to make. Can not believe how many of our friends and family have never had monster cookies. A staple growing up for the holidays!
Love this, Jesse! A staple for sure!
Best Monster Cookie recipe ever was a big hit!
Love reading this, Tammy!
Amazing! I am a world-class cookie snob and these are perfection in the mouth!!! Bravo!!!
Woohoo! I’m so thrilled you enjoyed the recipe, Kristin!
Mine did not spread out while baking Any ideas? They smell amazing but they are more balls than cookies
Hi Jen – There are several factors that may have attributed to this, such as how the heat circulated in your oven, your type of baking sheet and whether you used parchment paper or a Silpat. Perhaps next time you could flatten the dough slightly (after you’ve portioned it out)?
OmG these are SO SO AWESOME!! thank you for the recipe!!! My Kids Love them !! along with my Husband!!!
Woohoo! I’m so happy your family enjoyed the cookies, Kathy!
These are so delicious! A new staple in our cookie Arsenal!
I’m thrilled you enjoyed the recipe!
Loved these cookies delicious.
I’ve made these a few times and everyone loves them! I send them with my wife to work and her coworkers literally lineup to get one. Thanks for the recipe!
Love reading this, Grace!
Dough was very crumbly & Cookies did not spread at all in the oven. I scooped them onto the pan with a 3 tbsp scoop. When preparing the dough, I measured the peanut butter by weight. 1.5 cups is 24 tbsp. A tbsp of the pb I used weighs 33 grams, so I used 792 grams of pb. For my final pan of cookies, I added more pb to the dough before scooping them, hoping that would cause them to spread. Nope. Zero spread.
Ideas what went wrong?
Hi! I’ve never measured by peanut butter by weighing it so that is likely what caused your dough to be crumbly.
Everybody at work asked me for the recipe. I love these so much. Thank you for sharing.
I’m thrilled to read this, Denise!
THESE ARE SO GOOD and an all time favorite of mine!! My youngest and I made them this morning, for a fun and different Christmas cookie. We used Red and Green M&M’s. SO NUMMY!!
I’m thrilled to read this, Sarah! And I love the festive addition of red and green M&M’s!
Made these for a cookie exchange and for my family and they were gobbled up quickly! Thanks for sharing this recipe!
You are so welcome, Naomi!
My family eats these every few months. A good addition is coconut, it gives it some more flavor. Even though I’m a 7th grader, they are easy to make and SO good! Thank you so much!
So glad you’re enjoying the recipe, Elliana!
Would you say this is gluten free?
If you get all certified gluten-free ingredients, then yes! :)
These are the best. Am addicted!
I’m so thrilled you enjoyed the recipe, Peg!
These are delicious and the texture is the best! This recipe is definitely a keeper. Didn’t and won’t change a thing.
Woohoo! I’m so glad you enjoyed the recipe, Wendy!
Excellent cookies everyone loved them!!!
Can I get the nutritional values for these cookies? I need to track all of my fats, carbs, sugars, protein, cholesterol, etc.
Thank you!
Hi Susan – You can find the estimated nutritional info by clicking on the purple button below the recipe that says ESTIMATED NUTRITION INFORMATION. :)
Tillamook ice cream made me want to attempt to make Monster Cookies for the first time ever. This was the recipe I found and this will be the recipe I always use!! I can’t believe it worked without flour! I live in high altitude too, and they were perfect! Thank you!
Yay! I’m so thrilled you enjoyed the recipe!
Made these for work for Halloween did not change a thing in the recipe big, big hit!
I’m so glad you enjoyed the recipe, Tammy!
I have not made them yet. I have only salted butter and blue bonnet in my fridge. Can I use one of those for a substitute?
Thank you
Hi Angela! Salted butter works but I’d recommend reducing the 1/2 teaspoon salt because the cookies will be too salty.
can I use regular sized chocolate chips and m&ms
Absolutely!
The best. My favorite recipe ever
I’m thrilled you enjoyed the recipe, Michelle!
What are the nutrition facts please
Hi Bette – You can find the estimated nutritional info by clicking on the purple button below the recipe that says ESTIMATED NUTRITION INFORMATION. :)
This recipe by far is one of the best monster cookie recipes ever. I used your side note and I believe that was the trick! Thanks for sharing.
You are so welcome, Cindy! I’m so glad you enjoyed the recipe!
I had my first monster cookie about a year ago and fell in love. I’m no kid and I’m not sure how I had not found these years ago. I made your recipe and it did not disappoint. So yummy. I did make them smaller so I had 48 cookies instead of 24 much to my grandkid’s and neighbor’s delight. Thank you!
I’m so glad you enjoyed the recipe, Robin!
I made a double batch of these but only put in 1 recipes worth of sugar(so 2 cups total for the double recipe), tasted great just the right amount of sweetness for me. As a side note: a double recipe is too big for a 5 quart bowl on a Kitchen-aid
Thanks so much for your comment, Orchid! I’m thrilled you enjoyed the cookies!
Delicious!
Big hit with my husband and kids!
Made them today for Halloween . So easy!
I’m keeping this recipe in my recipe box.
Amazing! I’m so thrilled your family enjoyed the cookies, Amy!
I’d like to make these but was wondering if you can substitute the peanut butter with Sunflower butter (so they can be sent along with school lunches which are peanut free)? Thanks so much and Happy Halloween,
Hi Rosella! I’ve never tried that so I can’t say with certainty what the results would be. Let me know if you give it a shot!
I made these yesterday and they did not turn out well. I followed the recipe exactly but I put the dough in the fridge for a few hours before baking (this is what most choco-chip cookie recipes suggest). When I did bake them, they spread so much and while the bottoms browned, the middle was raw. I am not sure how I managed to get such thin cookies with a raw middle! The recipe does not call for any flour and maybe that is what it needed to stabilize the fat from the butter.
Hi Cat! This is a flourless cookie recipe and I wouldn’t recommend refrigerating the dough. Did you use natural peanut butter or regular?
We made these without the M&Ms because we didn’t have any. I must say they were delicious even without. Also the tip to let them cook more on the pain really helped!
I’m thrilled you enjoyed the recipe, Sandy!
These were a hit at my halloween party! Easy and delicious – adding to my personal recipe collection :)
Yay! I’m so thrilled to read this, Jaclyn!
Loved them. Made exactly as directed.
I’m so thrilled you enjoyed the recipe, Karen!
I made these for my husband today and he loved them. Thank you for a great recipe! How long will these stay fresh stored in an airtight container at room temperature?
They’ll stay fresh for about 5 days :)
Excellent recipe. Followed directions and came out perfectly. My mom added sunflower seeds (yes, even salted) to monster cookies I had when I was young so I added them to this. Very nice. Great recipe. Easy. Love the no flour. Thx for sharing
Awesome! I’m so thrilled you enjoyed the recipe, Guy!
4.5, and they taste great!
I’m so glad you enjoyed the recipe, Jonah!
Can I freeze this dough?
Hi Angela! Yes, this cookie dough freezes well. I recommend freezing it in balls/scoops so all you have to do is bake them off as needed.
Great cookie to make! I’d probably just add a tiny bit more peanut butter next time but that’s just a thought! Super yummy :)
I’m so glad you enjoyed the recipe!
Hands down the best monster cookie recipe I’ve made! Perfectly chewy and packed with flavor. I’ll be making these for all my family and friends! ❤
Yay! I’m thrilled you enjoyed the recipe, Jennette!
Loved the combination of oatmeal, peanut butter, and chocolate … Yummy!
These are so delicious! I follow the instructions but add regular sized M&Ms, chopped semi sweet chocolate and walnuts for an added textural element. I also sprinkle the dough with some flakey Maldon salt before they hit the oven. Will definitely make these all the time!
YUM! I’m so thrilled you enjoyed the recipe, Monique!
Best recipe. Everybody loves them!
My new favorite cookie! My family loves them and gobbles them up!
Turned out GREAT!! So delicious! Used my baking stone, preheated it first to put cookies on hot stone. 12 minutes, PERFECTION!!
Awesome! I’m thrilled you enjoyed the recipe, Donna!
Such a delicious cookie! Thank you so much for sharing! I will definitely be making these again.
I’m so glad you enjoyed the recipe, Kathy!
These look great and I can’t wait to try them!
I’m wanting to make a big batch of dough and freeze it so I can make a few at a time. Does Does this dough freeze well? Any tips?
Thanks!
Hi Amber! Yes, this cookie dough freezes well. I recommend freezing it in balls/scoops so all you have to do is bake them off as needed.
Great cookies! This was easy to make and the tip on underbaking and letting them cool on the baking sheet was so helpful. Thank you for a great recipe.
I’m thrilled you enjoyed the recipe!
These cookies are truly a hit in my family and our neighbors across the street! I make them and share them and the little neighbor boys just go crazy for them! I use the recipe as written, but use full size M&Ms.
Yay! So thrilled to read this, Micki!
Great recipe. My wife is GF and can’t eat chocolate, so we substituted Reese’s pieces for the M&Ms and carob chips for the chocolate chips (for her, not my batch).
I’m thrilled you and your wife enjoyed the cookies, Randy!
These were a hit at my house!
I’m so happy to read this, Kelly!
By far thee best monster cookies I’ve made! The family also loved it!!
I had several bags of random candies left over from making cupcakes. For the 2 cups of candies, I just mixed whatever I had, which was a huge variety. This recipe was fantastic for my odds and ends! Thank you!!!
I’m so thrilled you enjoyed it, Andi!
Made this recipe twice and both times they were fantastic!!! This recipe is a keeper!
I’m so thrilled you’ve been enjoying the recipe, Krystle!
Can’t wait to make these based on all the amazing reviews! My son has a peanut allergy so I’m wondering if I could substitute almond butter for the pb? Generally peanut butter is thicker than the almond butter so I’m not sure if it will mess with the texture of the cookie.
Hi Lucy! I’ve never made this recipe using almond butter so unfortunately I can’t weigh in on what the results would be.
My mom told me this was the second best cookie she has ever had, falling just short of her grandmothers famous spritz cookies. I did use 2 cups old fashioned and 2.5 cups quick oats, salted butter, and Mexican vanilla, so maybe that was the secret! Very good recipe. Will make for years to come!
So thrilled to read this, Shelby!
These were great! I divided the dough into 3 and cooked one pan and froze 2 bags with the other dough. There were great the first go around and just took the bag out yesterday to thaw and cooked today! My whole family loves these!
I’m so thrilled to read this, Jennifer!
Very good. I used Red Mill Old Fashioned Oats and Organic chunky peanut butter. 4 grandkids between ages 5-8 loved them and so did I.
Woohoo! So thrilled to read this, Lyda!
Wow! These are so good. Definitely will make again.
I rarely post reviews but this recipe is definitely one to talk about! I’ve made this recipe multiple times without fail. Spectacular cookies!
I’m so thrilled you’ve been enjoying the recipe, Tara!
These cookies were the BEST!
I’m thrilled you enjoyed them, Jacie!
This is such a good recipe. My son loves baking so we decided to try your recipe because it looked very close to the monster cookies from Target. Salty and sweet like our favorite trail mix but rolled up in a cookie. Yummy!
Amazing! I’m so thrilled you and your son enjoyed the recipe, Diane!
My family absolutely loved these! TY
I’m so glad to read this, Kimberly!
These are so good—and they taste about same as a favorite local bakery’s monster cookies. I used regular M&Ms and chocolate chips, but I didn’t have enough M&Ms. I subbed 1/2 cup of Reese’s pieces to make up the difference. Still excellent!
YUM! I’m so thrilled you enjoyed the monster cookies, Heidi!
Can you use regular Mand Ms. It would be fun to make these,in holidays colors.
Absolutely!
Loved this recipe! It’s our new favorite!
I’m so thrilled to read this, Tanya!
These were really delicious!
I’m thrilled you enjoyed the recipe, Jennefer!
Great recipe! I made these for a graduation party and everyone was calling me the cookie queen! They were definitely a hit. I’m making another batch now for my granddaughter’s baby shower. I scoop the dough out in balls and freeze them. They are ready to bake whenever I need them. Thanks for the great recipe!
Yay! I’m so thrilled you’ve been enjoying the recipe, Susan!
These cookies are amazing!! Everyone LOVES them!!
I’m so thrilled to read this!
Delicious!!! Everyone LOVES them! Thank you for the fabulous recipe – family favorite!
I’m so glad to read this, Maureen!
This is my go to cookie receipe and I bring them to all sorts of events and it’s a recipe people ask for everytime!! They are easy, delicious and our favorite!! Thanks for sharing your recipe!! YUM!!!
Love reading this! I’m thrilled you’ve been enjoying the recipe, Becky!
I was skeptical with this recipe using no flour, but they are great cookies. Glad that I decided to try the recipe. Thank you.
So glad you enjoyed them, Connie!
These are wonderful! Easy to make, and very flavorful! They are now my family’s favorite cookie! I was able to make them a little smaller and get 12/cookie sheet, so the baking went a little faster. Thank you so much!!
You are so welcome, Lisa! I’m thrilled you enjoyed the recipe!
Delicious!! I added raisins to the batter with M&M’s & chocolate chips. I didn’t have mini M&M’s or chocolate chips, so I used regular ones. Enjoyed these so much!!
Love your addition of raisins, Diane! I’m so glad you enjoyed the recipe!
absolutely loved this recipe… but cookies come out flat? or is that how they’re suppose to be?! HELP
Hi Anna – It’s hard to say what might cause flat cookies. Is your baking soda fresh?
My son gave these a 10.5 out of 10! So good!
Love reading this! I’m so glad the recipe was a 10.5, Jaena!
My husband is picky about his cookies and this recipe was a HIT! I’ve made a full batch and cut in half and it is perfect!
Woohoo! So thrilled to hear this, Shelly!
Made for a family get together where one family member is gluten free. These are really great cookies and I’m so glad the whole family can enjoy! I did leave out the vanilla, as I felt it would be overpowered by the PB and chocolate anyway.
I’m thrilled you enjoyed the recipe, Sarah!
Excellent cookie! Recipe so simple and easy to follow.
I’m so glad you enjoyed the recipe, Benny!
The cookies where BOM! but we were missing chocolate chips and M&M’s so instead we used butterscotch chips and it was so delicious! If you guys run out of these ingredients just substitute it with butterscotch chips!
Great swap, Adelyn! I’m so glad you enjoyed the cookies!
These are delicious! My whole family loves this cookie recipe. Thank you!
You are so welcome, Nicole!
Super yummy recipe! My husband I greatly enjoyed it, especially with a cup of coffee. I ran out of quick oats half way and used old fashioned oats too and it worked out just fine. I baked my cookies at 340 for 14 minutes, let them set cool down, and bam!
I’m so thrilled you enjoyed the recipe, Danni! Coffee + cookies = YUM!
WOW oh WOW!!! I saw the 5 stars and I’m so glad I made these. These taste great.
Yay! I’m so thrilled you enjoyed the recipe, Tracie!
Best monster cookies EVER! They truly are a family favourite. Adults love them as much as the kids!
Love this! I’m so thrilled the recipe was enjoyed by all! :)
Best monster cookie ever! I love the fact their is no flour. Love them!
I’m thrilled you enjoyed the recipe, Diane!
Turned out perfect! These cookies are there best! I love that they’re naturally gluten-free (more or less). I like them with chunky peanut-butter, but I use creamy for my son’s sake. I’m dairy-free, so I used a combination of coconut oil and Earth Balance instead of the butter. I like to make the dough without the mix-ins and use it as a crazy come dough. One son like blueberries mixed in. One likes chocolate chips. I like strawberries, blueberries, and chocolate chips. We don’t use M&M’s usually, but it is fun sometimes.
Love this! I’m so thrilled you are your family have been enjoying the recipe, Krista!
These cookies are a favorite in our house!! The baked cookies also freeze well for later.
I’m so thrilled you’re enjoying the recipe, Amanda!
Best monster cookies I have ever made. I have been looking for the perfect recipe for them and here it is.
So thrilled you enjoyed the recipe!
The best monster cookies! I have tried several recipes in the past and this recipe is definitely is the easiest and best tasting!!
I’m so thrilled you enjoyed the cookies, Krista!
Enjoyed and grandkids were very impressed !!
I’m so glad to hear this, Maureen!
Great recipe but I find 15 min is enough in my oven and this recipe cooks up 4 dozen cookies for me. My son has Down Syndrome and enjoys making these for friends and family because he can roll the balls of dough up and put Smarties on the top.
Love this! So thrilled you and your son have been enjoying the recipe, Connie!
I substituted a cup of flour and 3 1/2 c of oats. I also added Heath butter brickle bits with the mini chips and M&Ms. Lastly I refrigerate the dough for 8 hours in the fridge to blend flavors-outstanding!
I’m thrilled you enjoyed the recipe, Alexandra!
Fabulous! My family’s new-favorite cookie!
Yay! Love reading this, Lisa! I’m so thrilled you and your family enjoyed the recipe!
Great recipe! Liked the tip about leaving cookies on baking sheet 5-10 min. That does eliminate over baking. Didn’t have parchment paper and lightly greased cooky sheets worked just fine.
I’m so thrilled you enjoyed the recipe, Anne!
I had lost my recipe from my Mom for these cookies and they were the same as I remembered….Very Good. I use semisweet chocolate chips and regular oatmeal.
I’m so thrilled you enjoyed the recipe, Kimber!
Amazing! My go to cookie recipe that the whole family (including my GF needs) can enjoy ♡♡
I’m so glad you’ve been enjoying the recipe, Janelle! It’s one of my all-time faves!
This was a hit in our house!
Thrilled to hear this, Lyndsie! It’s a fave in our house, too :)
Made these this weekend as a little staying at home project.. they are LOVELY. I found 2 TBS works best size-wise. :)
I’m thrilled you enjoyed the recipe, Erin!
Can you use steel cut oats? That’s all I have right now! Staying home!!
Hi Emily – I wouldn’t recommend using steel cut oats as the cookies will be way too dense and heavy to bake to a proper consistency.
SO GOOD! I made these for the first time as indicated, except for the mix ins… Didn’t have mini chips or enough mini m&ms, so I used a combo of mini m&ms, reese’s pieces eggs, chopped dark chocolate peanut butter cups and some regular chocolate chips. Super easy to follow directions, came out perfectly!
Watch your oven… My big pan with 12 cookies was perfect at 12 minutes, but my smaller pan with 8 cookies was a bit over at 12 minutes.
Also, I used my ice cream scoop to form the cookies and this recipe ended up making 32. :)
Love your resourcefulness with the chocolate candies, Rebecca! I’m so glad you enjoyed the recipe :)
Mine are not flattening out?? Help!
Hi Hope! There are several factors that may have attributed to this, such as how the heat circulated in your oven, your type of baking sheet and whether you used parchment paper or a Silpat. Perhaps next time you could flatten the dough slightly (after you’ve portioned it out)?
I just want to be sure this doesn’t call for flour? This is the first time I’ve seen a recipe not call for flour
Correct, no flour!
Omg they turned out amazing reminded me of these cookies a special neighbor made for my family.I grew up with 7 brothers and sisters we all used to fight over them. During this hard time with covit 19 these made my family smile.
I’m thrilled you and your family enjoyed the cookies, Maribel!
Most delicious cookies ever! I added about a cup of butter scotch chips and used peanut butter m&ms instead. So good! I saved some of the dough to make one giant cookie in a skillet and added vanilla ice cream on top and it was the best thing I’ve ever tasted!
Oh.Em.Gee! I love that you made this into a skillet cookie!
Great recipe! I doubled it and was able to share big bags of cookies with three other people. I didn’t have enough M&Ms so I subbed Reese’s Pieces to make up the difference. Thank you for this wonderful recipe!
You are so welcome, Sara! I love the Reese’s Pieces substitution!
Love these I take them to work and never have leftovers. Great for people who need to stay away from wheat.
I’m thrilled you’ve been enjoying the recipe, Auralea!
Has anyone ever tried making these with gluten free quick oats?? Any modifications needed? Or do they turn out the same?
They should turn out the same, Amanda!
Mine didn’t turn out right they were completely flat is there any recommendations on what I should do differently?
Hi Rainna – It’s hard to say what might cause flat cookies. Is your baking soda fresh?
Cut the sugar and this cookie was still delicious!
I’m thrilled you enjoyed the recipe, Julie!
I just made these and I now have a new favorite cookie. Thank you for sharing the recipe I will treasure it and use it often.
I’m thrilled you enjoyed the recipe, Regina!
My first try and they are great!
I’m thrilled you enjoyed the recipe!
We LOVE these cookies! We have Celiac at our house so good cookies are priceless! I have made these for a party and our host called the next day for the recipe. They are chewy and so yummy! I would highly recommend them. We made them with regular sized chocolate chips and plain M&M’s and they work just fine.
I’m so thrilled you enjoyed the recipe, Brooke! It’s one of my all-time fave cookie recipes :)
I added extra chocolate and candy, and then sprinkled the cookies with coarse sea salt. Ohhhh yes.
YUM! So thrilled you enjoyed the recipe, Emmett, and I love your addition of coarse sea salt!
So easy and so good! I’ve made them several times now and they are a hit each time!
AMAZING! So thrilled you’ve been enjoying the cookies, Mel!
Easy to make and everyone loves them.
I like to add a cup of toffee bits also. Gives them just a bit of crunch.
Yum! Love that idea, Barry!
Made these and they were amazing! Everyone loved them! I used butterscotch chips in lieu of M&M’s, as I did not have them. They were terrific!
Amazing! I’m so glad you enjoyed the cookies, Cindy!
These are a hit at work, with the girlfriend, and the family. Love them.. hard not to eat 6 at a time. Ive used peanut butter m&ms and reeses pieces as well.
I’m so thrilled to hear this, Andrew!
Do you need to use a paddle attachment?
Hi Molly – You can mix it by hand! :)
Wow. I was intrigued by the story and recipe and then once I read all of the comments I was kinda sold. This is an excellent recipe. I snuck a taste of the batter before I added the oats and chocolate and it was so delicious. It was just like a soft supple loosened up peanut butter. I used old fashioned oats and doubled the recipe and it filled up the biggest bowl that I have. I used a mix of regular size m&ms, mini m&ms, regular size semi sweet chips and mini semi sweet chips. I will forever hang onto this recipe. I think what makes this recipe so great is the use of brown sugar and all of those eggs. Yum yum yum.
So glad you’re enjoying the recipe, Shelby!
We have made these many, many times since I found your recipe!
This is hands down THE best monster cookie recipe I have made!
Thank you for sharing it!
Woohoo! Love reading that, Sarah :)
Just made these. Love that it is flourless! They are so so good!!
I’m thrilled you enjoyed the recipe, Jeanette!
I have made these several times now and my family loves them. I’ve also been a little lazy and made them in bar form. They are quick and easy, and I always get rave reviews.
I’m thrilled you’ve been enjoying the recipe, Elizabeth! And I also have a recipe for Monster Cookie Bars that I love, too! (https://www.justataste.com/monster-cookie-bars-recipe/)
OMGGGGG this cookie is unreal delicious…I have already eaten
6 or maybe 7! Lol. I feel it would make a perfect base for any cookie. Tomorrow I’m making them with crunchy peanut butter minus the chocolate chips. Thank you for the recipe. You rock!
You are so welcome, Robin! I’m thrilled you enjoyed the cookies!
Delicious!!
I’m so glad you enjoyed the recipe, Missy!
Ok these are way to good wow yummy cant wait to hand out at work
I’m so glad you enjoyed the recipe, Kathy!
I have a batch in the oven right now never made a cookie without flour really interested in seeing the out come
This is one of my all-time fave cookie recipes, Kathy! Enjoy!
Would regular sized m&ms work? Just use a little less?
That’ll work!
These cookies were amazing! They had so much flavor, and they look really good! I would recommend these cookies to any baker! <- comment from my 9 yr daughter. We just made these for a cookie exchange.
Love hearing this! So thrilled you and your daughter enjoyed the recipe, Karl!
Do these freeze well?
Hi Wendy! I recommend freezing the cookie dough in balls/scoops so all you have to do is bake them off as needed.
Loved this recipe! I also used one whole bag of mini m&m’s and skipped the chocolate chips. I kind of guessed on the peanut butter as I only had natural on hand and I couldn’t get it stirred well. They still turned out excellent. I will definitely make them again.
I’m so thrilled you enjoyed the monster cookies!
These are perfect baked at 12 minutes. I used a whole bag of mini M&Ms and no chocolate chips or eyes.
I’m so thrilled you enjoyed the recipe!
Easy to make, but long time to cool. Super Yummy
I’m so glad you enjoyed the recipe, Patty!
Would this recipe work with natural peanut butter?
Yes!
I’m planning on making these ASAP! I am curious though, what would the difference be in using old fashioned vs quick oats?
Hi Jessica! The difference is in the resulting texture of the cookies. Quick-cooking oats offer a more delicate texture whereas old-fashioned oats offer a heartier one. :)
UNREAL! I have been on the hunt for the ultimate monster cookie recipe for years. Look no further, THIS IS IT! Brought them to work and had people begging for the recipe. Thanks for the tip to slightly under-bake for soft chewy cookies. #yum
LOVE hearing this! So thrilled you enjoyed the recipe, it’s one of my all-time faves!
I started dating a guy from Iowa, who claims this and Scotcheroos are a staple in that state. I decided to try this recipe, to give hin a feeling of home once in a while. They turned out great! I used some mini m&m’s mixed with the peanut butter m&m’s. It may seem like peanut butter overload, but they were awesome. Thank you for the recipe.
Is there such a thing as too much peanut butter? I don’t so! :) I’m so glad you enjoyed the recipe!
Made these today with a less sugar version. My husband is a diabetic so I used coconut palm sugar for the white and spenda brown sugar for the brown sugar. Still turned out great with less sugar. Everyone, even grandkids loved them. I just don’t tell anyone:)
Excellent! I’m so thrilled you enjoyed the recipe, Mary!
These are absolutely perfect! They don’t last long in our house!
Woohoo! I’m so thrilled to hear this, Christy!
I made these for the first time yesterday afternoon and they turned out fantastic! I followed the recipe to the letter and they came out great. The cookies initially didn’t spread much, so I pushed down a bit and then they baked perfectly. Seems to be something I have to do with a lot of cookies I make using the cookie dough scooper I have. I wound up using a mix of quick and old fashioned oats as I decided to use up the quick oats I had on hand. I was a little nervous with the no flour part, but these baked great and make a hearty and chewy cookie. Also, they’re so peanut buttery which is another plus. Next time I make these, I think I’ll sub out the plain M & Ms for Dark Chocolate ones as that is where my chocolate tastes skew. Otherwise, they are perfection!
Love this! I’m so thrilled you enjoyed the recipe, Nate!
I’m an Activities Director at a retirement community, and I was trying to find a eye catching recipe that would sell well during our Fall Festival. These are PERFECT! I was a bit nervous having never made flourless cookies, but I followed the recipe exactly, and these turned out perfectly. I was trying to decide between this and another recipe, and I’m so glad I chose yours. Many thanks for posting!
Love hearing this, Elena! I’m so thrilled you enjoyed the recipe!
I used an ice cream scooper to manage a uniform size. Made 2 dozen perfectly!
Woohoo! I’m so thrilled you enjoyed the recipe, Danette!
Yummy!!
I first made this recipe (or one very similar) when I was visiting my grandmother as a preteen. Definitely used an ice cream scoop and I’m sure the recipe that was in the newspaper made a ridiculous amount of cookies – lots for the freezer (and for us to sneak). These things hold up well for travel too. I brought a batch to an orphanage in India and there wasn’t a single one broken in the travels.
Thanks so much for sharing that memory of yours, Maureen!
Do you have to use parchment paper? and also why do you have to use parchment paper? there were a couple of recipes that I did see, that you could use on a little greased baking sheet? Why I am asking, I do not have that parchment paper or these Silpat baking mats in my house, But your recipe looks so easy to make, then all of the recipes I have looked at! I have all of your Ingredients that go into your recipe, and I only wanted to make about 2 dozen like your recipe calls for, Thank You, God Bless Lisa
Hi Lisa! The parchment prevents the cookies from sticking to the baking sheet.
They were great, even better the next day. I used maybe 1/2-3/4 the sugar and they were still sweet enough.
I’m so thrilled you enjoyed the recipe, Elli!
Wonderful Valentine’s Day treat for the kids! They really enjoyed the
I’m so glad you enjoyed the recipe, Leona!
I only have regular butter, so if I use it, what would be the measurement for the salt? Or just omit the salt all together?
Thank you for the recipe :)
Hi Linda! Yes, I would recommend leaving out or reducing the 1/2 teaspoon salt.
I made these cookies last night, I used old fashioned oats, chunky peanut butter and the regular sized m&ms, I baked them for 15 min and the cookies came out great, they chewy and perfectly golden brown! They taste better the next day
I’m thrilled you enjoyed the recipe, Shawna!
I had a hard time getting the peanut butter to cook all the way through in the middle. ~Help
Hi Katrina – Did you allow the cookies to cool for 5 to 10 minutes on the baking sheets?
Finally!!! Been looking for this recipe, like forever!! Thank you!! Can’t wait to make!! Yummy!!!
Enjoy the cookies, Debbie!
This cookie dough turned out to be more manageable than other ones I’ve tried (not as sticky and hard to work with). The instructions and measurements were very accurate and the results were Really delicious! I added a couple of teaspoons of cinnamon because I love cinnamon with everything. I will definitely make these again! We loved them. Thanks a million!
You are so welcome, April! I’m thrilled you enjoyed the cookies!
My family loves monster cookies! Pinning!!
Can you please clarify if you use rolled or quick oats in the cookies shown in the pics? And do you put the monster eyes on before or after baking? Too cute! Thank you.
Great questions! Updated the recipe :) Old Fashioned or Quick oats will work, and add the eyes immediately after baking. Enjoy!
Hands down my favorite cookies. Ever.
WOW! Thrilled to hear, Elizabeth!
Has anyone tried to half this recipe? I know it’s tough to half an egg but i’d like to try if others have been successful.
Hi Camile! I haven’t tried halving the recipe so I can’t say with certainty that it will work. Let me know if you try it!
Is your brown sugar measurement for packed brow sugar or not packed? It can make a difference & I want to make sure these turn out well, thanks! Any other tips on what ingredients to use & how to make them turn out well is greatly appreciated as I am a novice baker :)
Packed!
Wonderful recipes
Hi Kelly, I love your blog and can’t wait to make these cookies! I’ve seen cookie recipes (from other sites) that specify not to use natural peanut butter (the kind that separate) because it affects the final product. Do you know if that’s the case with your recipe? Thanks!
Yes! When baking, it’s best not to use natural peanut butter for this exact reason — the oils and other contents separate, which can cause strange consistencies in the cookies. Hope that helps!
Made these today – decided to chill the dough since it’s quite warm here (and humid). I ended up having to roll the dough into balls, just slopping them on the cookie sheet caused them to spread way thin when they cooled. Rolling them into 2-inch balls worked perfectly! No matter what they looked like, they taste fabulous. :)
I tried these and mine turned out flat both times. Help!
Hi Julia! My first question to troubleshoot would be to ask how old your baking soda is? If it’s too old, it won’t react properly and will cause the cookies to be flat. Hope this helps!
Does it matter if I use quick oats or not?
You can use quick oats or regular!
Definitely the Monster Cookies!
Thank u 4 all your nice recipes. It is better to put the dough a few hours in the fridge… then it will handle better. We call it: The dough must “rest”. Nice day to u all tomorrow.
Omg! Delishhh!! Made them with my 2 year old and we LOVE them!
If I made the dough the night before and refrigerated it until the evening after and then baked it, will it make any difference to the cookies? I’m making these tomorrow but I’ll also be out for most of the day.
Hi Sophie! I have never tried refrigerating and then baking the dough, so I cannot say with 100 percent certainty how they will turn out. They will bake up no problem, but it’s more a question of consistency. Next time I make the cookies I will test this out. Thanks!
Kelly – a reader of your blog made these for me and they were so amazing I emailed her for the recipe and ended up here. Congrats on your amazing blog and thanks for the great cookies :)
Wow! Just tried this recipe–the dough is fabulous…I’m sure the cookies will be as well. Thanks!
These cookies put Kelly Senyei on the map — back in 2005. A great recipe!!!!!
Molly used your recipe and made some monster cookies for me and Tyler today. Yum!
Thanks, Kelly! I’m going to try baking these this weekend. Yum.
