  • Preheat oven to 375°
  • Combine egg, butter, peanut butter and water
  • Add the gluten-free cookie mix and oats then combine well
  • Gently stir in the M&M's
  • Scoop with an ice cream scoop onto a greased or parchment lined cookie sheet (silicone mats work great as well) then flatten with the bottom of a glass cup
  • Bake 10-12 minutes
  • Let cool on a baking sheet for 3-5 minutes then transfer to a wire rack
  • Enjoy warm...easy peasy lemon squeezy!


  • Pro Tip: I have found that for this recipe, Bob's Red Mill mix works best. I also really like using the honey peanut butter because it adds a nice sweetness.
  • Gluten-Free Pro Tip: Always make sure to double check your ingredients and candies to make sure they are gluten-free. For example, regular M&M's are gluten-free but the pretzel ones are not.
  • To make these dairy-free, simply use a dairy-free chocolate chip cookie mix, dairy-free butter and dairy-free colored candies instead of M&M's. If you are also intolerant to egg, make a flax egg instead of using the regular one.
  • To make them peanut-free, simply use SunButter (for completely nut-free), almond butter or another nut butter that you prefer instead of peanut butter in the recipe. 
  • My favorite way to store leftovers is in a cookie jar but you can also place them in a covered container to keep them soft and chewy. They are good for 2-3 days after baking. 
  • Get creative and use leftovers to make monster cookie sandwiches! Follow instructions here for our Gluten-Free Vegan Ice Cream Sandwich Chocolate Chip Cookies and just use your leftover monster cookies instead.
