• 1 teaspoon unsalted butter, melted
  • 1/2 teaspoon ground cinnamon
  • 1 teaspoon erythritol or any keto-friendly sweetener


  1. In a microwave-safe mug, combine the almond flour, coconut flour, melted butter, erythritol, baking powder, ground cinnamon, egg, almond milk, vanilla extract, and salt. Mix well until the batter is smooth and well combined.
  2. In a small bowl, mix together the melted butter, ground cinnamon, and erythritol for the topping.
  3. Pour the topping mixture over the batter in the mug and use a toothpick or a fork to swirl it into the batter.
  4. Microwave the mug on high for 90 seconds to 2 minutes, or until the cake is set in the center. The cooking time may vary depending on your microwave, so keep an eye on it.
  5. Carefully remove the mug from the microwave (it will be hot) and let it cool for a few minutes.
  6. Optional: You can make a simple glaze by mixing together 1 tablespoon of powdered erythritol with a teaspoon of unsweetened almond milk. Drizzle the glaze over the mug cake.
  7. Enjoy your delicious Cinnamon Roll Keto Mug Cake!
