Sugar Free Lemon Mug Cake

Preparation Time: 5 minutes

Cooking Time: 1 minute 30 seconds

Serves: 1 mug cake

Difficulty: Easy

Course: Dessert

Cuisine: American

kcal: Approximately 120 kcal per mug cake


  • 2 tablespoons almond flour
  • 1 tablespoon coconut flour
  • 1 tablespoon powdered erythritol (or your preferred sugar substitute)
  • 1/4 teaspoon baking powder
  • Pinch of salt
  • 1 large egg
  • 2 tablespoons unsweetened almond milk
  • 1 tablespoon melted unsalted butter
  • 1/2 teaspoon lemon zest
  • 1/2 teaspoon lemon juice
  • 1/4 teaspoon vanilla extract


  1. In a microwave-safe mug, combine the almond flour, coconut flour, powdered erythritol, baking powder, and a pinch of salt. Mix well to ensure the dry ingredients are evenly distributed.
  2. In a separate small bowl, whisk the egg until well beaten. Add the unsweetened almond milk, melted unsalted butter, lemon zest, lemon juice, and vanilla extract to the egg, stirring until thoroughly combined.
  3. Pour the wet ingredients into the mug with the dry ingredients, stirring until you have a smooth batter without any lumps.
  4. Microwave the mug on high for about 1 minute 30 seconds or until the cake is fully cooked. Keep an eye on it while microwaving to avoid overcooking.
  5. Carefully remove the mug from the microwave (it will be hot!), and let the mug cake cool for a minute before enjoying.

Note: Microwaves can vary in power, so adjust the cooking time accordingly. The mug cake is done when it springs back lightly to the touch and the edges are slightly pulling away from the mug.
