I stole this recipe from Emily's Relief Society newsletter (the March edition) and I made it tonight. Super easy and super fast. Super yummy with some ice cream!
4 T flour
4 T sugar
2 T cocoa
3 T milk
3 T oil
3 T chocolate chips (optional...but who are we kidding, they're absolutely essential!)
1 small splash vanilla extract
1 large coffee mug
Add dry ingredients to mug and mix well. Add egg and mix thoroughly. Pour in milk and oil and mix well. Add chocolate chips and vanilla and mix again.
Put mug in microwave and cook for 3 minutes on high. The cake might rise over the top of the mug but don't be alarmed. Allow to cool a little and tip out onto plate if desired.
This can serve two, if you are feeling in a generous sort of mood.
