Directions:: Add the dry ingredients to your mug and mix very well. Add the egg and mix thoroughly. Pour in the milk and oil and mix well. Add the chocolate chips {if using} and vanilla, and mix again.
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 share!}
Additional:: And 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!
