Ingredients
Scale
- 2 tablespoons unsweetened cocoa powder
- 3 tablespoons granulated sugar
- 1 large egg, beaten lightly
- Optional: 1/4 teaspoon vanilla extract
- Optional: pinch of salt
- Optional: 1 tablespoon almond or oat milk (for dairy-free version)
Instructions
- Lightly grease the inside of a microwave-safe 12-ounce mug with butter or oil.
- Add 2 tablespoons of unsweetened cocoa powder and 3 tablespoons of granulated sugar to the mug. Stir briefly with a fork to combine and break up any clumps.
- Crack and lightly beat 1 large egg until yolk and white are blended, about 15 seconds.
- Pour the beaten egg into the mug with the dry mixture. Stir vigorously until the batter is smooth and uniformly chocolatey.
- If using, add a splash (about 1/4 teaspoon) of vanilla extract or a pinch of salt and stir again.
- Place the mug in the microwave and cook on high for 90 seconds. The cake should rise and spring back lightly to the touch.
- Carefully remove the mug and let it cool for 1-2 minutes before eating.
Notes
Adjust microwave time in 10-second increments if cake is undercooked or overcooked. Use a wider mug for even cooking. Greasing the mug helps with cleanup and texture. Optional add-ins like vanilla extract or a pinch of salt enhance flavor. For vegan version, substitute egg with flax egg.
