Add dry ingredients to mug and mix well. Add egg, mix thoroughly. Pour in milk, oil - mix well. Place mug in microwave for 3 minutes at 1000 watts. Cake will rise over top, but do not be alarmed. Allow to cool and tip out onto plate, if desired. Top with ice cream or whipped cream or melt chocolate chips with a tad of butter for an icing topping.
Why is this the most dangerous cake recipe in the world - because now we are all only 5 minutes away from chocolate cake, anytime - day or night!
