I know this blog is supposed to be about food, but I was so damn proud of myself for making this..... I decided to show you! You will need: cocoa powder, milk, a mug, a teaspoon, and sugar (optional). Firstly you will need to put 1 teaspoon of cocoa powder into a mug. Next, heat up some milk for about 4 minutes in the microwave. Pour the milk into the mug, add sugar and stir to create a swirl effect.
