Ingredients
Method
Step-by-Step
- Choose a microwave-safe mug that holds at least 10 ounces. Add the flour, sugar, cocoa powder, baking powder, and salt, then stir until the dry ingredients are evenly combined.
- Pour in the milk, oil, and vanilla extract. Stir from the bottom and around the sides until no dry pockets remain, then fold in the chocolate chips if using.
- Microwave the mug on high for 70 to 90 seconds, depending on the strength of your microwave. Stop when the top looks puffed and mostly set, with a little softness in the middle.
- Let the cake rest in the mug for 1 to 2 minutes because the center continues cooking from the retained heat. Serve warm with your choice of topping.
Notes
Use a wide mug for more even cooking and do not fill it more than halfway. Microwave power varies, so begin checking at 70 seconds to avoid a dry cake. Enjoy immediately for the best texture.
