Ingredients
Method
- Use a microwave-safe mug of at least 12 ounces (350 ml) with straight sides.
- Stir together the flour, cocoa powder, sugar, baking powder and salt in the mug until completely combined.
- Add the milk, oil and vanilla; stir until smooth with no dry flour at the bottom or sides of the mug.
- Stir in 1 tablespoon of the chocolate chips, then sprinkle the remaining 1 tablespoon on top.
- Microwave on high for 60-75 seconds, until the cake has risen and the top looks set but still soft. Add 10 seconds at a time if needed; never go past 90 seconds.
- Rest for 1 minute, then eat warm straight from the mug.
Notes
Start at 60 seconds and add 10 seconds at a time — mug cakes go rubbery fast. Do not overmix after the wet ingredients go in. Scrape the bottom of the mug so no dry flour hides there. A 12-ounce mug is the minimum or the cake will overflow. Best eaten in the first 10 minutes; reheat 10-15 seconds if needed.
