Add dry ingredients to mug, and blend well. Add egg; mix thoroughly. Pour in milk, oil and vanilla; mix well.
Blend in optional chocolate chips and nuts. Put mug in the microwave, cook 3 minutes on high. Cake will rise over the top of the mug, but don?t panic! Allow to cool a little, and tip out onto a plate if desired. Can serve two, if the person making it feels like sharing.

This recipe, e-mailed to me from friends, may be the most dangerous cake recipe in the world since it puts us only 5 minutes away from chocolate cake any time of the day or night!
