4 tablespoons flour
4 tablespoons sugar
2 tablespoons cocoa
3 tablespoons milk
3 tablespoons oil
3 tablespoons chocolate chips
A small splash of vanilla extract
1 LARGE coffee mug
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 desired.
EAT! (this can serve 2 if you want to feel slightly more virtuous).
AFTER POST EDIT:
This is Julie, we tried it, fun to make, really easy, smelled yummy, BUT, hard as a rock after cooling. I think my microwave is way more than 1000 Watts, will try an cook for half the time, because I cant give up on such an amazing idea and it worked for Amanda, maybe it is the crazy Kansas weather!
