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.

- 1 cup sugar
- 1 cup packed light brown sugar
- 1/2 cup unsalted butter, at room temperature
- 3 large eggs
- 1 1/2 cups peanut butter (smooth or chunky)
- 1 Tablespoon vanilla extract
- 2 teaspoons baking soda
- 1/2 teaspoon salt
- 4 1/2 cups oats (Old Fashioned or Quick)
- 1 cup mini M&Ms
- 1 cup mini-chocolate chips
- Candy eyes (optional)
- Pre-heat the oven to 350°F. Line two baking sheet with parchment paper or Silpat baking mats.
- In the bowl of a stand mixer fitted with the paddle attachment, cream together the sugar, brown sugar and butter until light and fluffy.
- Beat in the eggs, one at a time, and then beat in the peanut butter, vanilla, baking soda and salt until well combined.
- Add the the oats and mix until combined, then add the mini M&Ms and mini-chocolate chips.
- Scoop 2-to 3-tablespoon mounds of the dough onto the prepared baking sheets, spacing the mounds at least 2 inches apart.
- Bake the cookies for 12-15 minutes then remove them from the oven and allow them to cool for 5 minutes on the baking sheets before transferring them to a rack to cool completely. (See Kelly's Note.)
- The best way to guarantee your cookies are chewy and not too crispy is to underbake them slightly then remove them from the oven and allow them to cool for 5 to 10 minutes on the baking sheets.
- If you're using the candy eyes, add them to the cookies immediately after you remove them from the oven.

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 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.
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!
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!
“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?
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?
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?
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!
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.
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?
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 :)
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!
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.
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.
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.
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!
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.
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.
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.
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!
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!
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!
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!
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.
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!
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
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!
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.
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.
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?
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
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!
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?
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.
