Chocolate Mug Cake

Directions

1. 1
   Melt chocolate and butter in the microwave for 30 seconds. Remove and stir. If necessary, microwave again at smaller intervals of 10 seconds each time.
2. 2
   Add the sugar and stir to combine. Then add the egg and stir well, until completely smooth. Add the flour and stir just until combined and lump-free.
3. 3
   Pour the batter into a mug that can go into the microwave. Microwave (900 W) for 1 minute, for a moist cake, or 1 minute and a half if you prefer it more dry inside.
4. 4
   Let stand for 2 minutes before eating.
