Mix all the ingredients together in a bowl. Mix them with a whisk until smooth.
Pour the mixture into your favorite cup. Caution: Do not make more than 3/4 full, otherwise it'll go over.
At 600 watts, the cup cake takes 2 to 3 minutes.
Let cool briefly and then enjoy immediately.
Notes
And then, of course, it's time to decorate. To the chocolate Mug Cake fit Banana and Pear especially good. Coconut sprinkles or almond slivers make the protein cup cake even more beautiful and tasty.Yogurt also does well in the Mug Cake with chocolate flavor.
