What You’ll Need
- 2 tablespoons (1oz/28g) butter
- 1 egg
- 2 tablespoons milk
- 1 teaspoon vanilla extract
- 4 tablespoons sugar
- 6 tablespoons (50g/1¾ oz) self-rising flour (or make your own by adding 2 teaspoons baking powder to 150g/6oz/1 cup plain flour)
- Tiny pinch of salt
- Best-Ever Buttercream Frosting (for topping, optional)
How to Make It
- Melt the butter: Place the butter in a large mug and microwave for 20 to 30 seconds until fully melted.
- Whisk in the egg: Crack the egg into the mug and whisk it into the melted butter using a fork until combined.
- Add wet ingredients: Stir in the milk, vanilla extract, and sugar until the mixture is smooth.
- Mix in dry ingredients: Add the self-rising flour and a tiny pinch of salt. Mix with a fork until the batter is smooth and no lumps remain.
- Divide the batter: Split the batter evenly between two mugs.
- Microwave: Microwave each mug separately for 50 seconds, or until the cake has risen and is just set. Be careful not to overcook, as it can dry out quickly.
- Cool and decorate: Let the cakes cool slightly, then pipe or spread a swirl of Best-Ever Buttercream Frosting on top. Enjoy immediately!

Quick Storage and Reheating Tips
If you have leftovers (unlikely, but possible!), store the cake in an airtight container at room temperature for up to 1 day. To reheat, microwave for 10-15 seconds to restore its soft, fluffy texture. Avoid overcooking to keep it moist.
