Ingredients
Method
- Combine the Nutella, egg, and flour in a 10-ounce microwave-safe mug. Stir with a fork until smooth and glossy.
- Microwave on high for 1 minute, until the top is set and a toothpick inserted in the center comes out with moist crumbs.
- Let the mug rest for 1 minute, then eat the cake straight from the mug.
Notes
The cook time depends on your microwave's wattage. Start with 1 minute and add 10-second bursts if the center is still wet. For an 800W microwave, 1 minute 30 seconds usually does it.
