Preparation steps

  1. Gather and measure all the ingredients.
  2. Chop a tablespoon of dark chocolate.

Cooking steps

  1. Whisk the egg and erythritol in a large bowl until blended and slightly frothy.
  2. Pour in almond milk, vanilla extract, and coconut oil. Mix well.
  3. Fold in almond flour, cocoa powder, and baking powder. Mix everything thoroughly until you have a smooth batter with no lumps.
  4. Stir in the chopped dark chocolate for an extra flavor boost.

  6. Microwave the mugs at 800W for 3 minutes and 30 seconds until the cake rises and sets.
  7. Once done, carefully take out the mugs. Test the cake's doneness with a toothpick - it should come out clean. If not, microwave for an additional 15-30 seconds.

Chef's pro tip

The perfect mug cake is all about the batter's consistency. If it feels too thin, mix in a tablespoon of almond flour. A tablespoon of almond milk will do the trick if it's on the thicker side. Remember, microwave strength affects the cooking time. Also, the cake will keep cooking from residual heat even after you take it out!
