WHISKAFFAIR'S
Stir together all-purpose flour, sugar, cocoa powder, and baking powder in a microwave-safe 16 oz mug using a fork or a small wire whisk.
Add butter, milk, egg, and vanilla extract to the mug and whisk everything well.
Place the chopped dark chocolate over the batter and top gently with water.
Keep the mug in the microwave and cook for 1 minute on high. Check the cake. The edges should be set and the center should be very slightly wet and sticky. If not, cook for another 15 seconds.
Top with a scoop of vanilla ice cream or whipped cream and some strawberry slices. Serve immediately.
