Cake in a Mug!

Everybody loves cake. But sometimes you're too lazy or too impatient to bake a whole cake.
Solution?
Cake in a mug. The best use for a microwave I have yet found.

Find a large mug. Then find these things:

3 tablespoons flour
1 teaspoon sugar
2 teaspoons cocoa powder
1/4 teaspoon baking powder
Pinch of salt
2 tablespoons milk (Or water, or coffee.)
1 tablespoon oil (Or like half of a banana)
1 tablespoon peanut butter (Or jam, chocolate sauce, or whatever you like)
Some chocolate chips. (You know, if you like those.)

Mix everything up in your mug, then microwave the mess for about 1 minute.

Hooray, instant cake!
