  • 1 ¼ cup gluten free flour blend * see note
  • ½ cup almond flour * see note
  • 1 cup brown sugar
  • ¾ cup butter melted
  • ½ cup peanut butter * see note
  • 1 large egg
  • 1 teaspoon baking powder
  • teaspoon salt
  • 1 teaspoon pure vanilla extract
  • ½ cup chocolate chips


  • Preheat the oven to 350º F.
  • In a large bowl, combine all of the dry ingredients and whisk to blend.
  • In a medium sized bowl, add all wet ingredients. (You may need to soften the peanut butter in the microwave for 10 seconds to soften if it is hard.) Mix well.
  • Pour the wet ingredients into the dry ingredients. Add M&Ms or chocolate chips and mix well.
  • Use coconut oil to grease an 8x8 baking pan.
  • Spread the cookie dough in the pan.
  • Bake 22-24 minutes until done.
  • Allow to cool and slice into bars.



  1. I have tested this recipe with King Arthur Measure for Measure GF and Bob's Red Mill 1 to 1 GF blend. That doesn't mean others will not work, I just have not tested other flours.
  2. If your gluten free flour blend doesn’t contain xanthan gum or guar gum, please add 1 teaspoon.
  3. To make this recipe dairy-free, substitute the butter for vegan butter.
  4. I highly suggest using almond flour and not almond meal. Almond meal is more coarse and will make your cookie bars grainy.
  5. To test for doneness, insert a toothpick into the center of the bars. If the toothpick comes out clean, it is done baking. If you see batter or crumbs, the cookie bars need to bake longer.
