  3. Add in the buckwheat flour, cocoa, baking powder, optional cinnamon, sweetener, and the additional 3 tablespoons of water.
  4. Mix everything together to form a smooth, thick, cake batter.
  5. Microwave the cake on high for 1 minute. If the batter needs more time, add another 10-30 second interval.
  6. To make the frosting, simply mix together the protein powder with the water until you get your desired consistency.
  7. Top the cooked mug cake with the frosting and top with optional mini chocolate chips and sprinkles.
