Cake in a Mug

I tried this cake in a mug recipe several years ago but I pretty much burned it, so I decided to give it another try.

Ingredients used:
4 tablespoons all purpose flour
4 tablespoons granulated sugar
1 egg
3 tablespoons cocoa powder
3 (heaping)tablespoons Nutella
3 tablespoons milk
3 tablespoons vegetable oil

Directions:
1. Combine all the dry ingredients.
2. Add the remaining ingredients.
3. Mix everything with a fork until smooth.
4. Put in the microwave for 1 1/2 minutes.
5. Cool. Top with ice cream and enjoy.
