Donut Mug Cake - cooking recipe

Ingredients

1 tablespoon unsalted butter
1 egg yolk
2 tablespoons milk
1/2 teaspoon vanilla extract
3 tablespoons sugar
6 tablespoons self-rising flour
For topping
1/2 cup powdered sugar
1 tablespoon milk
scant drop red food coloring
colored sprinkles

Preparation

Put the butter into a microwave safe mug and microwave for 20 seconds to melt.
Add the egg yolk, milk, vanilla and sugar, then stir with a fork to combine. Add the flour and stir vigorously until batter is smooth. Microwave for 90 seconds to 2 minutes, until the cake has risen and top of the cake is firm to the touch.
Let cool for 2 minutes before decorating.
In the meantime whisk together the confectioners' sugar with the milk until smooth. Use food coloring to dye glaze pink.
When cake is cool, using a melon baller, scoop out a deep divot into the center of the cake. Top with glaze spreading to coat evenly allowing a bit to fall into the center and drip down the sides.
Sprinkle with sprinkles and serve.
