The most dangerous chocolate cake in the world

OK, OK - I know it's a bad juxtaposition putting chocolate cake next to dieting but...
I'm the type of person that usually deletes round-robin, chain letter emails but this one got past my guard, and I'm rather glad! Part of the appeal was the fact that I didn't have to forward it to at least 10 people if I wanted to avoid dire consequences. The main appeal is its simplicity and its taste!

5 minute chocolate mug cake
4 tablespoons SR flour
4 tablespoons sugar
2 tablespoons cocoa
1 egg
3 tablespoons milk
3 tablespoons oil
3 tablespoons chocolate chips (optional)
A small splash of vanilla extract
1 large mug

Add dry ingredients to mug and mix well.
Add the egg and mix thoroughly.
Pour in the milk and oil and mix again.
Add the chocolate chips (if using) and vanilla extract and make sure all ingredients are well combined.
Put the mug into 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.
Now EAT! (This can serve 2 if you want to feel more virtuous.)

So why is this the most dangerous cake in the world? Because now we are only ever 5 minutes away from chocolate cake at any time of the day or night! Enjoy.
