5-minute chocolate cake in a mug

We finally made this tonight. It was fun to watch it rise, rise, rise to what seemed an impossibly tall (and unsustainable) height a few inches above the top of the mug and *instantly* drop when the microwave stopped.

This is a great recipe for kids to watch. There are very few crumbs in this cake. It holds together quite well.

Ingredients
4 TBSP flour
4 TBSP sugar
4 TBSP cocoa powder
1 egg, beaten
3 TBSP milk
3 TBSP oil
3 TBSP chocolate chips (optional)
A small splash of vanilla extract
1 large coffee mug

Preparation

1. Add dry ingredients to mug, and mix well.
   
2. Beat the egg in a small bowl, then pour in the milk, oil, and vanilla extract and mix well.
3. Add the wet ingredients to the dry ingredients in the mug. Mix thoroughly.
   
4. Add the chocolate chips and mix slightly.
5. Put your mug in the microwave and cook for 3 minutes at 1000 watts.
   

The cake will rise over the top of the mug, but don't be alarmed!
Allow to cool a little, and tip out onto a plate if desired.
Eat! (This can serve 2 if you want to feel slightly more virtuous.)

Why is this the most dangerous cake recipe in the world? Because now we are all only 5 minutes away from chocolate cake at any time of the day or night!
