  • 1 tbsp unsalted butter melted
  • 1 large egg
  • 3 tbsp superfine almond flour
  • 1/2 tsp baking powder
  • 1 tbsp + 1 tsp erythritol sweetener granular
  • 1/2 tsp vanilla
  • 1/2 tsp cinnamon

Cinnamon Sugar Topping

  • 1/16 tsp ground cinnamon
  • 1/4 tbsp erythritol sweetener granular


  1. In a microwave-safe mug (that can hold at least 12 oz of liquid), add all cake ingredients. Mix with a small whisk until batter is smooth.

  2. In a small bowl, add topping ingredients. Whisk until evenly blended. Sprinkle over surface of cake.
  3. Cook cake in microwave at full power for about 1 minute 30 seconds. Be careful to not overcook the cake because that will cause the cake to be dry when it cools. Allow the cake to cool a few minutes before eating.

  • I used Kirkland Signature superfine almond flour.*
