Ingredients needed

This gluten-free monster cookies recipe is a fun twist on your everyday chocolate chip oatmeal cookies! Packed with texture, from the tender cookies to the hearty oats and crunchy candies and nuts, these are perfection. Hereโ€™s everything youโ€™ll need to make them:

  • Peanut butter: Use natural peanut butter for that classic flavor, or change it up and use almond butter or cashew butter.
  • Eggs: Two eggs will ensure these cookies bake properly.
  • Coconut oil: Provides the perfect amount of moisture.
  • Sugar: Use either coconut sugar or brown sugar for the perfect amount of sweetness.
  • Rolled oats: Old-fashioned rolled oats provide such wonderful texture.
  • Baking essentials: Baking powder and baking soda for the perfect rise and chewy texture.
  • Cinnamon and vanilla: Will add extra delicious flavor.
  • Mini M&Mโ€™s: We like using the mini M&Mโ€™s because they get dispersed throughout the dough better than the regular size. However, you may use chopped up regular M&Mโ€™s.
  • Chopped nuts: Chopped pecans, walnuts or almonds add a nutty crunch.
  • Chocolate chips: We like mini dark chocolate chips, but any chocolate chips will work great.
  • Unsweetened shredded coconut: Adds extra texture and flavor. If youโ€™re not a fan of coconut, feel free to omit it.

How to make this recipe

This M&M monster cookie recipe is simple and you only need one bowl! Plus, thereโ€™s no need to chill the dough! Here are the easy steps on how to make these m&m cookies:

  1. Prep: Preheat the oven to 350ยบF and line a sheet pan with parchment paper.
  2. Mix wet ingredients: In a large mixing bowl, add the peanut butter, eggs, coconut oil, coconut sugar, and vanilla. Mix to combine.
  3. Add dry ingredients: Next, add in the oats, baking powder, baking soda, and cinnamon. Mix them together until they are well incorporated.
  1. Add mix-ins: Fold in the M&Mโ€™s (only 1/4 cup-half the amount), nuts, dark chocolate chips, and shredded coconut. Mix again to combine.
  1. Scoop dough: Using a large spoon or a cookie scoop, scoop even amounts of dough and evenly space them out on the prepared sheet pan.
  1. Bake: Top the each with the remaining M&Ms. Place the sheet pan in the oven and bake for 11-13 minutes or until they are slightly golden brown.
  1. Cool: Allow the cookies to cool for about 5-10 minutes and then transfer them to a wire rack to continue cooling for another 10 minutes. Enjoy!

Expert tips

  • Bake on parchment: To ensure even baking and nice, thick cookies that donโ€™t spread, we recommend baking on parchment paper or silicone baking mats.
  • Cookie thickness: Once you place the dough on the pan, you can press then down with your fingers or a spoon before baking for a thinner cookie. If you like your cookies to be more on the thick side, do not flatten the dough.
  • Gluten free oats: Oats are naturally gluten free, but sometimes during farming, transportation and storage, they come in contact with gluten-containing grains. To ensure these cookies are gluten free, be sure that your oats have a label indicating they are gluten free.
  • Double the recipe: This recipe makes 16 cookies. If youโ€™re feeding a crowd or serving these during the holidays, consider doubling the recipe.

Variations

We love this monster cookie recipe as written, but feel free to get creative and experiment with your favorite ingredients! Hereโ€™s some options:

  • Different baking chips: You can sub the dark chocolate chips with white chocolate, semi-sweet chocolate chips, milk chocolate chips or even peanut butter chips.
  • M&Mโ€™s: Use a different variety of M&Mโ€™s. Peanut butter M&Mโ€™s would be delicious!
  • Nuts: If youโ€™re not a fan of nuts, feel free to omit them. Or use any favorite nut! Pecans, walnuts, almonds or peanuts are all great.
  • Oats: You can use 1 cup rolled oats, or for a slightly less oat-y texture use 1/2 cup instant oats and 1/2 cup rolled oats.

Storage recommendations

  • To store: These can be kept at room temperature for the first day or two, then store them in an airtight container in the refrigerator for up to 5 to 7 days.
  • To freeze: Allow the cookies to completely cool, and then transfer them to an airtight container lined with wax or parchment paper or freezer-safe bag before storing them in the freezer for up to 2 months. Once ready to eat, simply thaw at room temperature.
