These Healthy Gluten Free Monster Cookies are for all those peanut butter and m&ms lovers. They are lightened up, flourless peanut butter cookies packed with tender oats and chocolate chips. It’s one of the world’s best gluten-free cookie recipes!
Where my COOKIE MONSTERS AT?? I made you (healthier) gluten-free monster cookies because I just couldn’t help myself.
When I had my siblings over for cookie decorating Christmas eve, I made those (amazing) little pretzel kiss m&m treats – you know the ones. They’re basically a must for the holidays. Well, when I started the pretzel kiss assembly I realized I forgot to pick up m&ms. *DOH*
So I asked my sister to bring me a bag of red and green m&ms on her way over. But what she brought me instead was a ginormous bag of regular m&ms. Which was fine because I
made asked my little brother to pick out all of the red and green ones for the pretzel kiss treats 😀 But then that still left me with a big ol’ bag of m&ms. I mean, there are only so many green and red m&ms per regular bag, ya know?
Healthier Gluten-Free Monster Cookies
So anyways, I don’t like to leave candy sitting out because I WILL eat it – especially m&ms. I just can’t help but love those little coated bites of chocolate. So I stuck the bag in the pantry out of eyesight and told myself I’d make some cookies with them at a later date.
Well, that date is now, my friends. I was in Panera the other day and noticed those colorful monster cookies staring me in the face. So I knew I had to make a Healthier, Gluten Free Monster Cookie recipe of my own!
But what does “healthier” mean in this case? We’re using less butter, less sugar and just oats as the binder (no all-purpose flour). Thankfully, these flourless cookies are still loaded with flavor and satisfy the sweet tooth craving.
Ingredients For Peanut Butter Monster Cookies
- gluten-free quick oats
- baking soda
- peanut butter
- coconut or brown sugar
- vanilla extract
- non-dairy milk
- mini chocolate chips
How to Make Gluten Free Monster Cookies
- Preheat oven to 350ºF. Line a large baking sheet with parchment paper.
- In a medium bowl, combine oats, baking soda and salt.
- In large bowl of a stand mixer or using an electric hand mixer, beat together peanut butter and sugar for about 1 minute. Scrape down sides of the bowl, then beat in softened butter. Add in egg and vanilla.
- Add in 1/2 the bowl of dry ingredients, milk and begin beating on low speed. Then add the rest of the dry ingredients until combined; dough will be thick and just slightly soft.
- Add in mini chocolate chips and m&ms and gently fold.
- Scoop dough with a medium cookie scoop and drop onto cookie sheet, flattening slightly with palm of the hand. Add more m&ms to tops of cookies.
- Bake for 7-9 minutes. Remove from oven and allow cookies to cool before transferring to a cooling rack. Enjoy!
To ensure your cookies are gluten-free, make sure to buy oatmeal that is certified gluten-free.
The healthy gluten free cookies in the photos are made with rolled oats, but I made them again with quick (baby) oats and they came out softer and chewier! If you only have rolled oats on hand, pulse 4-5 times in your food processor to break them down slighty!
Tips For The Best Gluten Free Monster Cookies Recipe
- Use quick oats for the best texture. If you only have old-fashioned rolled oats, pulse a few times in your food processor as noted above!
- Natural peanut butter offers the best flavor, just make sure to stir before mixing into the cookie dough. A Natural JIF or Skippy will also work.
- Evenly space cookies on the parchment lined baking sheet to ensure even cooking.
- For dairy-free, replace the butter with an equal amount of softened coconut oil and make sure to use dairy-free mini chocolate chips!
How To Store
These gluten free m&m cookies will keep best stored in the fridge in an airtight container for up to 1 week.
To freeze, transfer to a plastic freezer storage bag, seal, label, date and store in the freezer for up to 1 month. Remove from the freezer for 5 minutes to take the chill off before enjoying!

Add more m&ms to tops of cookies, if desired. These cookies won’t spread much, so you want to flatten them slightly.

2019 – recipe slightly updated to include more peanut butter and a couple minor tweaks for better results after reader feedback. They hold together much better now!
*I tested these with both quick oats and rolled oats. While both worked okay, the quick oats held the cookies together slightly better. The pictures are shown with rolled oats but I would recommend quick oats for the best results. However, if you only have rolled oats on hand, you can use those. OR pulse them *slightly* in a food processor to break them up.
**I used a natural peanut butter with just peanuts and salt for the ingredients. If you choose to use a creamy peanuit butter (i.e. JIF), that should also work.
