  • 2 ½ tablespoons cocoa powder * see note
  • 1 ½ tablespoons gluten free flour blend * see note
  • 2 tablespoons sugar
  • 2 tablespoons light oil * see note
  • 2 ½ tablespoons water
  • ½ teaspoon pure vanilla extract
  • 1 tablespoon chocolate chips


  • In a small bowl, add the dry ingredients and whisk to blend.
  • Add in the wet ingredients and the chocolate chips and mix well.
  • Pour into your favorite coffee mug.
  • Microwave on high for 90 seconds. If the brownie feels firm to the touch, it is ready!
  • Top with vanilla ice cream.


  1. I have tested this recipe with King Arthur Measure for Measure GF, Bob's Red Mill 1 to 1 GF blend, and Authentic Foods Multi 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. There are many gluten free brands of cocoa powder. I like Rodelle, Anthony's, and Ghirardelli brands. Always check the label to make sure the cocoa powder you choose is gluten free!
  4. This mug brownie will keep up to 4 days in an air-tight container, or up to 4 months in the freezer.
