Quick microwave sponge cake for 1 person

In a mixing bowl whisk together all the ingredients.

Put the mixture into a microwave safe bowl and cover tightly with cling wrap. Don't put holes in the cling wrap becuase it needs to steam. It will dome up in the microwave but don't worry, it's supposed to do that.

Put into the microwave on full power for 3 1/2 minutes until fully cooked. Remove the cling wrap immediately or the cake will get dense. The picture below shows what it should look like.

Serve with the topping of your choice. I chose golden syrup but you could use jam, lemon curd, anything you want really.
