Mug Chocolate Cake?

I randomly saw this recipe and was very intrigued...its quick, easy, and the perfect portion...if I ever get around to making it I'll let you know if its the real deal. If you try it let me know how it turns out...I hope its comparable to Molten Chocolate Cake gooey goodness.

4 tablespoons 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 (Microwave Safe)

1.Add dry ingredients to mug, and mix well.
2.Add the egg and mix thoroughly before pouring in the milk and oil in. Keep mixing.
3.Add the optional chocolate chips next (who makes that an option!) and vanilla extract, and mix again
4.Put your mug in the micro wave and cook for three minutes at 1000 watts. The cake will rise over the top of the mug, but don’t be alarmed!
5.Allow it to cool a little, and tip out onto a plate if desired.
6.EAT! (this can serve two if you want to feel slightly more virtuous).
