  • ¼ cup gluten free flour blend * see note
  • 2 tablespoons brown sugar
  • ½ teaspoon baking powder
  • tiny dash salt
  • ½ banana smooshed (see note)
  • ½ teaspoon pure vanilla extract
  • 1 egg large
  • ¼ cup almond milk * see note
  • 1 tablespoon butter * see note


  • In a bowl, add the gluten free flour blend, sugar, baking powder, and salt and whisk to blend.
  • In another bowl, add the smooshed banana, butter, egg, vanilla, and milk. Whisk to blend.
  • Pour the wet ingredients into the dry ingredients and mix until just barely mixed.
  • Put the cake batter into a microwave-safe mug and microwave for 90 seconds.
  • Check the top of the cake with your finger. If it is a bit sticky, microwave an additional 35 seconds and re-test. The exact time will vary depending on how tall and wide your mug is.
  • Dump the cake out onto a plate for cooling.
  • Allow to cool and top with frosting, ice cream, or whipped cream


1. If your banana is not ripe, you can bake it at 225º F for 20 minutes to ripen. If you have more time, just put the bananas into a brown paper bag for 1-2 days.
2. 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 in this recipe. That doesn't mean others will not work, I just have not tested other flours.
3. You can use regular milk or any non-dairy milk in this recipe.
4. If you want to make this recipe dairy-free, use coconut oil instead of the butter.
5. You can use any type of nut in this cake, or omit the nuts to make this recipe nut-free.
