Gluten-Free Monster Cookies

  • Author: Jamie
  • Total Time: 35 minutes
  • Yield: 12 giant cookies 1x
  • Diet: Gluten Free


These easy one-bowl Gluten-Free Monster Cookies are chewy, thick, deliciously soft, and the BEST cookies I have ever eaten!



Wet Ingredients

  • 1 cup butter (I used dairy-free butter), softened at room temperature
  • 1/2 cup creamy peanut butter
  • 1 1/2 cup granulated sugar (I used coconut sugar)
  • 2 large eggs
  • 1 teaspoon vanilla extract

Dry Ingredients

  • 2 and 2/3 cups gluten-free all purpose flour (I recommend Bob's Red Mill 1 to 1 or Pamela's All-Purpose)
  • 1 teaspoon baking soda
  • 1/4 teaspoon salt


  • 1 cup shredded unsweetened coconut
  • 1 1/4 cup M&M's or alternative (see notes)
  • 1 cup mini chocolate chips


  1. Prep: Grease or line two cookie or baking sheets. Preheat the oven to 350 degrees F.
  2. Mix wet ingredients: In a large mixing bowl, add the butter and use an electric mixer to cream until smooth. Add peanut butter and sugar and cream again for at least one minute until well-mixed. Add eggs and vanilla and mix until just combined.
  3. Add dry ingredients: Add gluten-free flour, baking soda, and salt to the bowl. Mix until just combined. 
  4. Add mix-ins: Add coconut, M&M's or alternative, and chocolate chips. Mix until evenly distributed throughout the dough.
  5. Make dough balls: Use a large 1/4 cup (4 tablespoons) ice cream or cookie scoop to make balls. Lightly compact each one with your hands before placing on the baking sheet, allowing a couple inches between them for spreading.
  6. Bake: Bake for 9-11 minutes. The cookies are done when the edges are set and the dough has a light brown crust.
  7. Flatten if needed & enjoy: If the cookies have not spread, use the back of a measuring cup to press them down slightly to flatten. This will occur if you used cold (rather than room temperature) butter and eggs. Allow to cool for 5 minutes before transferring to a cooling rack. Enjoy!


Storage: Store in an airtight container on the counter for up to 3 days.
