Delicious, indulgent, healthy and it takes less than 10 minutes to whip up this tasty dessert! Did we mention it contains peanut butter!
Combine the flour, baking powder and protein together in a bowl. Add in the wet ingredients (except the chocolate chips), and mix until smooth.
Stir in half the chocolate chips and place the mixture in a lightly greased mug or small bowl. Put this into the microwave for 60-90 seconds (this can vary depending on the power of your microwave).
Top with the leftover chocolate, extra peanut butter and anything else you fancy!
