  • 3 tablespoons gluten free flour blend * see note
  • ½ teaspoon baking powder
  • 1 egg large
  • 3 tablespoons sugar
  • 2 tablespoons coconut oil
  • ½ teaspoon pure vanilla extract
  • 2 tablespoons lime juice
  • 1 teaspoon lime zest

For the Icing

  • 3 tablespoons powdered sugar for icing
  • 1 teaspoons lime juice for icing


  • In a small bowl, add flour, sugar, and baking powder. Add in the egg, melted coconut oil, lime juice, and lime zest.
  • Mix well. Pour into your favorite mug. (I used a spray coconut oil to spray the sides of the mug so the cake doesn't stick.)
  • Put into the microwave for 90 seconds.
  • Put the powdered sugar and lime juice in a small bowl and mix. Drizzle onto the mug cake.


  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. I used almond milk but other dairy-free kinds of milk will work but I do not recommend canned coconut milk.
  4. To test for doneness, touch your finger to the top of the cake. If it feels firm, your cake is done cooking.
  5. Make sure your mug is microwave safe!
