Keto Lemon Mug Cake Recipe:


  • 2 tbsp almond flour
  • 1 tbsp coconut flour
  • 1/4 tsp baking powder
  • Pinch of salt
  • 1 tbsp unsalted butter, melted
  • 1 large egg
  • 1 tbsp lemon juice
  • 1/2 tsp lemon zest
  • 1/4 tsp vanilla extract
  • 1-2 tbsp granulated keto-friendly sweetener (e.g., erythritol, stevia) to taste
  • Optional: a few drops of liquid stevia for added sweetness


  1. In a microwave-safe mug, mix together the almond flour, coconut flour, baking powder, and salt.
  2. Stir in the melted butter, egg, lemon juice, lemon zest, vanilla extract, and the granulated sweetener. Mix well until the batter is smooth.
  3. Taste the batter and adjust the sweetness to your liking by adding a few drops of liquid stevia if desired.
  4. Microwave the mug cake on high for 1 minute and 30 seconds to 2 minutes. The cooking time may vary depending on your microwave’s power, so keep an eye on it to avoid overcooking. The cake should rise and become firm to the touch.
  5. Carefully remove the mug from the microwave (it will be hot) and let the cake cool slightly before enjoying.
