All you need is a spoon, a mug, a tablespoon, and a microwave.
2 tablespoons butter or margarine
3 tablespoons sugar
2 tablespoons cocoa powder
A pinch of baking powder
2 tablespoons water
4 tablespoons flour
Put the butter in the mug and microwave on high for 30 seconds or until melted. Add the sugar, cocoa, and baking powder and stir until smooth. Add the water and stir again. Add the flour and stir one more time, scraping as much of the batter down off the sides as possible. Microwave on high for 1 minute and eat! Add a scoop of ice cream to make it even better.
