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 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!
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!
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
