Gluten Free Monster Cookies

Gluten free monster cookies are a flourless take on the classic favorite cookie. These easy peanut butter oat cookies feature m&m’s and mini chocolate chips so that there is chocolate in every bite!

Monster cookies are always a hit cookie and typically made with peanut butter, m&m’s and chocolate chips.

We love eating monster cookie energy balls for a healthier snack.

These cookies take all those flavors, but instead create a flourless monster cookie made instead with gluten free rolled oats.

My flourless peanut butter oatmeal chocolate chip cookies are still one of my most popular cookies and my gluten free peanut butter cookies are another favorite.

I love peanut butter and oat recipes, like my gluten free cookie bars. Oats are a great way to add texture and chewiness to gluten free desserts.

Flourless Monster Cookies Ingredients

  • Creamy Peanut Butter: the no stir variety
  • Vanilla Extract
  • Eggs
  • Pure Maple Syrup
  • Brown Sugar
  • Gluten Free Rolled Oats: if you are not gluten free, regular rolled oats will be fine. If you are cooking for someone with a gluten intolerance, it is best to buy specifically marked gluten free oats.
  • Baking Soda
  • Mini Chocolate Chips: I love using mini chocolate chips for chocolate in every bite.
  • M&M’s: I used full sized, but mini ones would work too
  • Salt: just a touch to accent the sweetness of the cookies

Step 4: Shape the cookies onto the baking sheet. They will not change shape or rise much. Top with more m&m’s, if desired.

Step 5: Bake the monster cookies at 350 degrees for 12 – 15 minutes, until lightly browned on the tops.

Allow the cookies to rest on the pan for 5 minutes, then transfer to a wire cooling rack.

Be careful not to over bake the cookies, as they will continue to cook on the pan.

These gluten free monster cookies are a family favorite and my kids go crazy for them!

We even froze the leftovers and they reheated great in the microwave.

Yes! If you wanted to, you could easily freeze the cookie dough to have fresh baked monster cookies on hand for any time the craving strikes.

To freeze cookie dough, roll it into balls and place on wax paper inside an airtight container or ziploc bag.

You can cook frozen cookie dough from frozen, just add a few extra minutes onto cook time.

If you have never tried this, I highly recommend it! I love being able to grab cookie dough straight from my freezer and have homemade fresh baked cookies in minutes.
