How to Make It
In a microwave-safe mug, combine the flour, sugar, cocoa powder, and baking powder.
Add the milk, vegetable oil, and vanilla extract. Stir until smooth.
If using, sprinkle chocolate chips on top of the batter.
Microwave on high for about 40-60 seconds, or until the cake has risen and looks set.
Serve
Let it cool for a minute, then dig in with a spoon. The center will be warm and gooey, making it the perfect treat for any chocolate lover.
