Ingredients
Method
- Add the flour, sugar, cocoa powder, baking powder, and salt to an 8 oz glass jar. Whisk with a fork until evenly combined.
- Pour in the milk, oil, and vanilla. Stir until the batter is smooth and no dry flour remains at the bottom. Fold in the chocolate chips if using.
- Microwave on high for 60 to 90 seconds, until the cake has puffed and the center appears just set. Rest 30 seconds, then top with ice cream and serve warm from the jar.
Notes
Microwave wattages vary widely, so start with 60 seconds and check. The cake will continue to cook a little after you pull it out. If the center is still very jiggly, microwave in 10-second bursts until it looks set but shiny.
