Monster Cookies

from 439 votes

Preheat your oven for a classic flourless Monster Cookies recipe that’s been in my family for more than two decades.

Monster Cookies studded with mini chocolate chips and M&Ms

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.

Monster Cookies studded with mini chocolate chips and M&Ms
Prep Time 15 minutes
Cook Time 20 minutes
Total Time 35 minutes
Servings 24 cookies

Ingredients 

  • 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)

Instructions 

  • 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.)

Kelly's Notes

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.

    Hi, there. Have you ever frozen the dough??? If so, would I bake them straight from the freezer or thaw and then bake?

    I had great success making these smaller using the small cookie scoop that’s 1 1/2 tablespoon. In my oven, I baked them for 11 1/2 minutes. YOU ABSOLUTELY MUST LET THESE SIT ON THE BAKING SHEET FOR AT LEAST 30 minutes to set up properly. Longer for the 3 tbsp size cookies.

    Excellent recipe that allows you to experiment with add-in’s.

    Thank you for sharing.

    1. Kelly Senyei says:

      So glad you enjoyed it, Lisa! Yes, I’ve frozen it before. To bake from the frozen state, you’ll just need to add a few more minutes to the bake time. Enjoy!

  2. Shar says:

    I have a recipe very similar to this from who knows when. I can hardly read the recipe card any longer. But this is a smaller batch. I just made my recipe with my grandson to earn a badge. So I’ll have to wait and try your recipe some time later. But thank you for this.

    1. Kelly Senyei says:

      Enjoy, Shar!

    How to cook at 325° instead of 350° because it was starting to burn the bottom of the cookies

    1. Susan M Schmitz says:

      Whenever I make sourdough bread I always put another pan or pizza stone on the bottom rack. It never burns the bottom of the bread anymore. Maybe it will work the same for cookies

      1. Kelly Senyei says:

        Great idea, Susan!

  4. Alicia says:

    Best cookie recipe ever! I’ve never really liked baking cookies but this one is so easy and everyone loves them! My granddaughter gives them a solid 7.5-8. I give them a 10+.

    1. Kelly Senyei says:

      Love that you’re both enjoying the recipe!

  6. Steven says:

    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.

    1. Kelly Senyei says:

      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.

    1. Kelly Senyei says:

      So glad you enjoyed it, Andrew!

        So glad you enjoyed the recipe, Kathy!

      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!

    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.

    1. Kelly Senyei says:

      I’m so glad you enjoyed the recipe, Rebecca!

  17. Michelle says:

    5 stars
    This will be my “go to” monster cookie recipe! They turned out great!

    Wonderful chewy cookies! Didn’t change a thing!

    1. Kelly Senyei says:

      I’m so glad you enjoyed them Rebecca!

  19. Karen says:

    5 stars
    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.

    1. Kelly Senyei says:

      I’m so glad you enjoyed the recipe!

  20. Kristin says:

    5 stars
    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!

    1. Kelly Senyei says:

      I’m so thrilled to read that, Kristin!

  21. Bree says:

    5 stars
    This recipe turned out great!! I was worried they’d crumble with no flour but they look exactly like the pictures!

    1. Kelly Senyei says:

      I’m so happy you enjoyed the recipe, Bree!

  22. Jan says:

    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!

  23. Rachel says:

    5 stars
    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!

    1. Kelly Senyei says:

      I’m so glad you enjoyed the recipe, Rachel!

    2. krista says:

      5 stars
      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.

      1. Kelly Senyei says:

        I’m so glad you enjoyed the recipe, Krista!

  24. Missy says:

    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

    1. Kelly Senyei says:

      So glad you enjoyed the recipe, Missy!

  25. Donnie says:

    5 stars
    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!

    1. Kelly Senyei says:

      Thrilled you all enjoyed the recipe, Donnie!

  26. Anh says:

    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.

    1. Kelly Senyei says:

      Hi Anh! It sounds like your butter was too warm.

      1. Asha M says:

        5 stars
        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?

      2. Kelly Senyei says:

        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!

  27. Kristi says:

    4 stars
    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”.

    1. Kelly Senyei says:

      Hi Kristi! Did you confirm your oven temp was correct and your rack was in the center? It sounds like a temperature issue!

  28. Becky B says:

    5 stars
    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.

    1. Kelly Senyei says:

      I’m so thrilled to hear that you enjoyed the recipe, Becky!

  29. Ronna says:

    Can these be put in freezer after baking?

    1. Kelly Senyei says:

      Absolutely, Ronna! Just let them cool completely before packaging them in an airtight container.

  30. Emerson says:

    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!

    1. Kelly Senyei says:

      Hi Emerson! Halving the egg gets tricky, however this dough freezes beautifully and will last for months if stored in an airtight container.

  31. MaryAnn says:

    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

    1. Kelly Senyei says:

      Hi, MaryAnn! Let me know how the cookies turn out when you and your grandchildren try them!

  32. Sandy says:

    My new go-to cookie recipe. They’re the first to be eaten at Christmas.

    1. Kelly Senyei says:

      I’m thrilled to hear that you enjoy the recipe, Sandy!

  33. Kristin says:

    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.

    1. Kelly Senyei says:

      I’m so glad to hear that you enjoyed the recipe, Kristin! The added pretzels sounds great!

      1. Leesa says:

        5 stars
        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.

      2. Kelly Senyei says:

        I’m so thrilled you all are enjoying the recipe, Leesa!

  34. Shelley Billingsley says:

    No flour?

    1. Kelly Senyei says:

      Correct! No flour needed in this recipe.

  35. Rach says:

    5 stars
    Delicious and addictive! I only use 1/2 or even 1/4 of the sugar though and they are still plenty sweet!

    1. Kelly Senyei says:

      So glad you enjoyed the recipe, Rach!

    2. Mary Ella says:

      I was thinking of reducing the sugar too. So it didn’t affect texture or bake time, etc.?

      1. Kelly Senyei says:

        Hi Mary Ella! I haven’t tried reducing the sugar so I’m not sure what the outcome would be.

  36. Suzanne says:

    What if I decide to make the cookies smaller, only one scoop? How long should they bake?

    1. Kelly Senyei says:

      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.

    1. Kelly Senyei says:

      This makes me so happy, Rebecca. Thank you for sharing such a sweet memory. I hope you all had a wonderful Thanksgiving!

    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!

        this is the best monster cookie recipe ever. I was wondering what can i do to make it a little less dry?

      2. Kelly Senyei says:

        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!

  42. Andrea Combs says:

    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!!

    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.

    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.

    1. Kelly Senyei says:

      I’m so thrilled to hear that you and your daughter enjoyed making them and that they were a hit at the party, Nalani!

  45. Allison Hill says:

    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.

    1. Kelly Senyei says:

      So glad you enjoyed the recipe, Allison!

  46. Kathy says:

    4 stars
    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.

    1. Kelly Senyei says:

      Glad that trick worked, Kathy!

  47. Ziggy says:

    5 stars
    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.

    1. Kelly Senyei says:

      I’m so thrilled to hear that you’re enjoying the recipe, Ziggy! Great idea adding the chopped pecans and hazelnuts!

    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.

    1. Kelly Senyei says:

      You are so welcome, Alice! I’m thrilled you enjoyed the recipe and I love the idea of using toffee pieces!

      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.

      1. Kelly Senyei says:

        Hi Sadie! Did you let the melted butter cool for 15 minutes before continuing with the recipe?

  51. Melind says:

    4 stars
    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!!

    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!!!

  54. Cassidi says:

    5 stars
    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!

    1. Kelly Senyei says:

    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.

    1. Kelly Senyei says:

      Thanks for your note, Lee!

  56. Tracy says:

    This is our favorite Monster Cookie recipe! Thanks for sharing!

      You are so welcome, Tracy! I’m thrilled you’ve been enjoying the recipe!

      1. Madelyn Kudronowicz says:

        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.

      2. Kelly Senyei says:

        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.

    1. Kelly Senyei says:

      So glad you enjoyed it!

  58. Tania says:

    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!

    1. Kelly Senyei says:

      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.

      2. Kelly Senyei says:

        Woohoo! I’m so happy to read this, Helene!

  59. Kaitlyn says:

    Why does the butter and sugar take SO LONG to cream together? it’s been 30 minutes and still not light and fluffy!!

    1. Kelly Senyei says:

      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.

    1. Kelly Senyei says:

      Yay! I’m so glad you enjoyed the recipe, Lyndie!

  61. Denise Peters says:

    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.

    1. Kelly Senyei says:

      I love a recipe that’s been around for generations! :)

  62. Madi Lindblom says:

    5 stars
    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.

    1. Kelly Senyei says:

      Love, love, LOVE reading this, Madi! I’m thrilled you and your husband enjoyed the cookies!

  72. Barry says:

    5 stars
    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

  74. Marsha says:

    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.

    1. Kelly Senyei says:

      YUM! I’m so glad you enjoyed the recipe, Marsha!

  77. Elizabeth Miller says:

    Toooo much sugar!! Made them so sweet and a little too runny. Delicious otherwise!

    1. Kelly Senyei says:

      Thanks for your note, Elizabeth. Try reducing the sugar amount by 25% next time :)

  78. Tina says:

    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.

    1. Kelly Senyei says:

      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

    2. Taryn says:

      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!

    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.

    1. Kelly Senyei says:

      Love this, Charlotte! I’m so thrilled you enjoyed the cookies. :)

    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.

    1. Kelly Senyei says:

      YES! The best recipes stand the test of time.

    2. Sallie Foster says:

      Is it better to use quick oats or old fashion?

      1. Kelly Senyei says:

        Hi Sallie – Either work! Quick-cooking oats offer a more delicate texture whereas old-fashioned oats offer a heartier one. :)

  88. Angie Danner says:

    My family loved them . Very tasty and soft . Made them for our Christmas gathering. Will make again .

  89. Jesto says:

    I measured out cookies in 6 grams. Rolled them in a ball then slightly flattened. Cooked for 15-17 minutes. Good stuff!

    1. Kelly Senyei says:

      So glad you enjoyed the recipe!

    2. Pauline says:

      Can you make the monster cookie without the peanut butter and add a different kind of nut?

      1. Kelly Senyei says:

        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!

  90. Jeanine says:

    Hi Kelly. Have you ever made these with Splenda? Any adjustments?

    1. Kelly Senyei says:

      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!

    2. C.R. Moore says:

      5 stars
      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.

      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!

      1. Kelly Senyei says:

        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.

  92. Hocking Suz says:

    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!

    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.

    1. Kelly Senyei says:

      Hi Sarah! Using an entire 1 cup less of oats is going to greatly alter the recipe and lead to different results.

        Thanks, Amber! That would work great :)

      2. Kelly Senyei says:

        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.

  94. Jilliannie says:

    5 stars
    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!

    1. Kelly Senyei says:

      Yay! I’m so glad you enjoyed the recipe, Jilliannie (despite having to bake 75 million batches )!

    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!

    1. Kelly Senyei says:

      I’m glad they still worked out, Alisha! :)

    1. Kelly Senyei says:

      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!

    5 stars
    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 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?

    2. Bex says:

      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!

      1. Kelly Senyei says:

        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!

      2. Caine says:

        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.

  108. Emily says:

    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.

    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.

    1. Kelly Senyei says:

      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!!

    1. Kelly Senyei says:

      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!

    1. Kelly Senyei says:

      Hi Lora! I use 3-tablespoon mounds of the dough, but any size works!

    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.

    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’!

    1. Kelly Senyei says:

      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!

    1. Kelly Senyei says:

      You are so welcome, Becky! I’m thrilled you’ve been enjoying (and sharing!) the recipe! :)

  131. Cody says:

    4 stars
    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.

    1. Kelly Senyei says:

      Thanks for your note, Cody! I’m thrilled you enjoyed the cookies!

  132. Michelle says:

    Has anyone had any success with reducing the sugar a bit?

  133. Micayla says:

    5 stars
    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!

    1. Kelly Senyei says:

      You are so welcome, Micayla! I’m thrilled you enjoyed the recipe!

  134. Barb Hansel says:

    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.

    1. Kelly Senyei says:

      Excellent! I’m so glad you enjoyed the recipe, Barb!

  140. Ayla says:

    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!

    1. Kelly Senyei says:

      Woohoo! I’m so thrilled you enjoyed the recipe, Ayla!

        Always great cookies!
        But this time I made them with Biscoff Cookie Butter and Reese’s Pieces!!
        Yup still a breakfast cookie!!

  143. Nancy says:

    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.

        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!

    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!

    1. Kelly Senyei says:

      Love, love, LOVE reading this, Cait! My boys are sprinkle-obsessed, too :)

  148. Laurie Willey says:

    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!!!

    1. Kelly Senyei says:

      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.

      1. Lys says:

        So, does this recipe call for course kosher salt? It just says salt on the ingredients.

      2. Kelly Senyei says:

        Correct, Lys!

      LOVE this! I’m so thrilled your family has been enjoying (and sharing!) the cookies, Jaena.

  151. Julie Boyer says:

    5 stars
    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!!

    1. Kelly Senyei says:

      Yessss! I’m so thrilled you enjoyed the recipe, Julie!

    2. Kendra Dayton says:

      I made these today and they tasted good but where flat and chewy.. could I add an additional minute or 2

      1. Kelly Senyei says:

        Hi Kendra – It’s hard to say what might cause flat cookies. Is your baking soda fresh?

  152. Tamy says:

    5 stars
    Adding raisins are wonderful just 2 boxes and a Lil less oats. For chewier cookies a Lil less time on the oven

    Are you able to prep the dough a day in advance and refrigerate?

    1. Kelly Senyei says:

      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!

      1. Barbara Sadlier says:

        5 stars
        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.

      2. Kelly Senyei says:

        Excellent! I’m so glad you enjoyed the recipe, Barbara!

    2. Bek says:

      5 stars
      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 :)

      1. Kelly Senyei says:

        Thanks so much for your note, Bek! I’m thrilled you enjoyed the recipe!

    5 stars
    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.

    1. Kelly Senyei says:

      I’m so thrilled you’ve been enjoying the recipe for so long! It’s one of my family’s all-time faves :)

    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.

    Can you subsitute almond butter for peanut butter? We have a peanut allergy in the family :(

    1. Kelly Senyei says:

    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!

  176. Laurie says:

    4 stars
    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!

    1. Kelly Senyei says:

      Love it! I’m so glad you enjoyed the recipe, Laurie!

    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?

    1. Kelly Senyei says:

      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!

    2. Judy says:

      I have a dairy allergy and have successfully made these with a vegan butter substitute. They are delicious.

    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!

    1. Kelly Senyei says:

      Love this! I’m so thrilled you enjoyed the recipe, Kelly!

  181. Cindi says:

    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.

    1. Kelly Senyei says:

      Thanks for your note, Cindi!

    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.

    1. Kelly Senyei says:

      Haha! My husband would agree! I’m so thrilled your family has been enjoying the cookies, Angel :)

      1. Maya says:

        Are these gluten free? Or have a very low amount of gluten?

      2. Kelly Senyei says:

        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.

    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.

    Delicious cookies! Doubling the recipe will make the mixer overfill so you may just want to mix up one recipe at a time.

    1. Kelly Senyei says:

      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?

  187. grace engle says:

    how many cookies does this recipe make, been making these for yrs. & their my no. 1 cookie

    1. Kelly Senyei says:

      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.

  188. Bill Cummings says:

    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.

    1. Kelly Senyei says:

      Love, love, love reading this, Bill! I’m thrilled your family has been enjoying this recipe for so many years. :)

    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.

    1. Kelly Senyei says:

      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?

    3. Kelsey says:

      Mine definitely went flat. Not sure what I did wrong. I used no name smooth peanut butter.

      1. Kelly Senyei says:

        Hi Kelsey – It’s hard to say what might cause flat cookies. Is your baking soda fresh?

  199. Sherry says:

    For a peanut allergy what could you substitute peanut butter with.

    1. Kelly Senyei says:

      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!

    2. Amy says:

      Hi do you know if I add anything or take anything away for high altitude?

      1. Kelly Senyei says:

        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!

  200. Ellie says:

    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?

    1. Kelly Senyei says:

      Hi Ellie! It may work if you drain the excess oil from the top of the peanut butter!

  204. Marlynn says:

    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… ‍♀️

    1. Kelly Senyei says:

      Hi Marilynn! This dough will be too wet to roll into balls. You’ll want to use a scoop or two spoons.

  208. Cathy says:

    3 stars
    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.

    1. Kelly Senyei says:

      Hi Cathy – I’m sorry you didn’t enjoy the recipe. I’ve never experienced there being too many chocolate chips or M&Ms.

    2. Marlynn says:

      Kathy, there is a small discrepancy on the x2 butter calculation. You need 2 sticks, not 1. Might explain your issue. Try again!

  213. Aunt Tracy says:

    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!

    1. Kelly Senyei says:

      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!

  214. Suhita says:

    Some of the best cookies I’ve ever made – my friends absolutely loved them!

    1. Kelly Senyei says:

    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.

    1. Kelly Senyei says:

      Thanks, Teresa!

  216. Renee says:

    I want to add peanut butter to this monster cookie! How much would you recommend adding ? These look so goooood

    1. Kelly Senyei says:

      Hi Renee – This recipe calls for 1 1/2 cups peanut butter.

    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.

    1. Kelly Senyei says:

      You are so welcome, Krissi! I’m thrilled your family enjoyed the cookies!

    5 stars
    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

    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!

    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

    1. Kelly Senyei says:

      So glad you enjoyed the recipe, Mary!

    2. Ereka says:

      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!

      1. Kelly Senyei says:

        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!

      2. Arianna says:

        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.

      3. Kelly Senyei says:

        Love this! Thanks so much for sharing, Arianna!

    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.

    1. Kelly Senyei says:

      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.

  237. Laura Seekings says:

    5 stars
    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.

    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!

    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.

    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.

    1. Kelly Senyei says:

      Hi Sylvie – Thanks for catching that! Please follow the cup measurements. :)

    Great cookies! As cookie dough without the eggs is so delicious chilled too!

    Turned out very good. Made several times now trying to use up oatmeal.

  264. Philip Shin says:

    Hi! I just made your recipe last night for my friends, but I’m seeing some of them in a week. Will the cookies last a week or should I make another batch next week? Please let me know, thank you!

    Also, I was skeptical initially because this recipe uses no flour and a lot of oats, but they turned out perfectly!

    Best,
    Philip

    1. Kelly Senyei says:

      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. :)

  265. Jessica says:

    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?

    1. Kelly Senyei says:

      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!

    1. Kelly Senyei says:

      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!

    1. Kelly Senyei says:

      Woohoo! I’m so thrilled you enjoyed the recipe, JoAnne!

  268. Rosie Hay says:

    These taste much more like a granola bar than a cookie. They’re not bad. But not what I was expecting

    1. Kelly Senyei says:

      Interesting! I’ve never thought these tasted like a granola bar, Rosie. Did you follow the recipe as written?

  269. Kelsey Acheson says:

    Hi! What kind of mini chocolate chips? Semi sweet?

    1. Kelly Senyei says:

      Hi Kelsey! Any variety will work but I prefer semi-sweet. :)

    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

    1. Kelly Senyei says:

      haha, love this! I’m so thrilled that you’re enjoying the cookies, Amy!

  272. TJ says:

    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.

    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…

    1. Kelly Senyei says:

      Awesome! I’m so thrilled you’ve been enjoying the recipe!

  276. Courtney says:

    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?

    1. Kelly Senyei says:

      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 :)

  277. Shannon says:

    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!

    1. Kelly Senyei says:

      Awesome! I’m so thrilled you enjoyed the recipe, Shannon!

  280. Jessica Robinson says:

    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!

  283. Mike says:

    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.

    1. Kelly Senyei says:

      Sorry!

    Absolutely delicious! We added a cup of mini Reece’s peanut but cups and pieces…so good!

    1. Kelly Senyei says:

      YESSSSS! So thrilled you enjoyed the recipe, Sarah!

  285. Mike says:

    Just curious but approx how many calories in a cookie? Of course I couldn’t tell eat just one. They were awesome!

  286. Lan says:

    Would it be ok to replace sugar with maple syrup?

    1. Kelly Senyei says:

      Hi Lan – Using maple syrup will result in a completely different taste/texture.

  289. syrena says:

    yield?

    1. Kelly Senyei says:

      Hi there! The recipe yields about 24 cookies, it all just depends on how big you make your cookies.

  290. Michele Paradise says:

    3 stars
    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. :(

    1. Kelly Senyei says:

      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!

  291. Dara says:

    How would you go about storing these to bake for later??

    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!

    1. Kelly Senyei says:

      I’m so thrilled to read this!

  294. JJ says:

    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?

    1. Kelly Senyei says:

      Correct, no flour! :)

  295. Stephanie G. says:

    5 stars
    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!

    1. Kelly Senyei says:

      I’m so thrilled you enjoyed the recipe, Stephanie!

  296. Jaime says:

    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?

    1. Kelly Senyei says:

      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)?

    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!

    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!

    Mine did not spread out while baking Any ideas? They smell amazing but they are more balls than cookies

    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?

    1. Kelly Senyei says:

      Hi! I’ve never measured by peanut butter by weighing it so that is likely what caused your dough to be crumbly.
