5 tbs all-purpose flour
2 slightly rounded tbs unsweetened cocoa powder
2 slightly rounded tbs sugar
1/8 tsp baking soda
1/8 tsp salt

mix these ingredients together in a mug and add

3 tbs milk
2 tbs oil
1/4 tsp vanilla
1/4 tsp white vinegar

mix it all up and here's the great part... lick the spoon ... no eggs, no worries

you can add some chocolate chips or nuts now if you want

put it in the microwave for 1 minute, maybe 1 and a half. check it at one though... since there are no eggs it cooks really fast...
if the top is bouncy and a fork stuck in it comes out clean, its ready.
Its good with a scoop of ice cream dumped right into the mug.
