Step 1

Melt the chocolate and butter in an 11-12 ounce mug (~40 seconds, stir every 20 seconds) just until the chocolate is almost melted. Stir the melted butter and mostly melted chocolate until it's smooth and completely melted.

Step 2

Mix in the sugars and then the egg white (make sure the mixture has cooled before adding the egg white so that it does not turn into scrambled eggs). Stir with a fork until the mixture is slightly thick (1-2 minutes).

Step 3

Add the flour, baking cocoa and salt. Gently stir with the fork until no flour streaks remain.

Step 4

Microwave the mixture on 50% power for 30-40 seconds. Enjoy!*
