Five minute chocolate mug cake

I realise this is going to get me into a lot of trouble here, however I just received the following recipe via email (yes, yes, I know it's cheating, but come on, tell me you don't want to know this!):

Ingredients
4 tablespoons self raising 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 coffee mug

Method
Add dry ingredients to mug, and mix well.
Add the egg and mix thoroughly. Pour in the milk and oil and mix well. Add the chocolate chips (if using) and vanilla extract, and mix again.


Put your mug in the microwave and cook for 3 minutes at 1000 watts(high). 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 you feel like being proper about the whole thing, but really, you just made a a cake in a mug, it'd be like having a Cup O' Soup in a bowl).

This can serve 2, if you like and are feeling virtuous...


But I doubt it, so go ahead and eat the whole thing on your own and be sure to enjoy it thoroughly.

I'm sure you can play around with the ingredients (for instance, why is the oil in there?), if you do so, please let me know how you go.

Otherwise, you can thank me later when you've licked your fingers and wiped the chocolate from around your mouth.
