In a large mug or small bowl at least 12 oz in size add egg, almond milk and banana
Mash banana and mix well into the egg mixture.
In the same mug or bowl add coconut flour, almond flour, powdered stevia, baking powder and cinnamon. Mix well into the egg mixture to form a batter.
Add chocolate chips and mix into batter.
Microwave for 1.5 minutes in 30-second increments waiting 5 seconds between rounds. The batter will rise while cooking and then fall when it is done cooking. I find this helps keep the batter from rising too quickly and spilling out over the top.
Allow cooling for 1 minute before eating. The mug will be very hot so be sure to remove with oven mitts or wait till cooled enough to handle before removing from the microwave.
