- 2 tbsp almond flour
- 1 tbsp cocoa powder unsweetened
- 1 tbsp erythritol or your favorite keto sweetener
- 1/4 tsp baking powder
- 1 tbsp butter melted
- 1 tbsp heavy cream
- 1/4 tsp vanilla extract
- 1 large egg
In a microwave-safe mug, combine the almond flour, cocoa powder, sweetener, and baking powder. Mix well using a fork or small whisk.
Add in the melted butter, heavy cream, vanilla extract, and the egg. Stir until the batter is smooth and well combined.
Optional: fold in a few sugar-free chocolate chips or a pinch of cinnamon for extra flavor.
Microwave on high for 60–90 seconds, depending on your microwave's strength. The cake should rise and set but still be moist in the center.
Let it cool for 1 minute before enjoying straight from the mug or transferring to a plate.
Optional: top with whipped cream or a few raspberries for a fancy touch.
For a dairy-free version, substitute the butter with coconut oil and the heavy cream with almond milk.
This recipe is easily customizable—try adding a touch of peppermint extract or a few chopped nuts.
Be careful not to overcook the mug cake or it may turn rubbery—every microwave is a little different, so start with 60 seconds and check for doneness.
