  • 2 tbsp sugar-free chocolate chips
  • 1 tbsp butter melted
  • Pinch of salt
  • ¼ cup unsweetened almond milk
  • ½ tsp baking powder

  2. Add the batter to your favorite mug (or mugs) leaving at least 1.5 inches of space from the batter to the top of the mug, to allow the mug cake to rise and avoid spills.
  3. Microwave for 3 minutes, check the cake, it should be soft but not wet. If it is wet microwave for another 30 seconds. (it is very important to avoid overcooking since it may become dry).
