4 Tablespoons flour
4 Tablespoons granulated sugar
2 Tablespoons cocoa
3 Tablespoons milk (I used soy)
3 Tablespoons canola or vegetable oil (or 1.5 Tablespoons oil and 1.5 Tablespoons applesauce)
Coat inside of mug with cooking spray. Mix flour, sugar, salt and cocoa. Stir in egg. Pour in milk and oil and combine thoroughly.
Put in microwave for 3 minutes on maximum power (1,000 watts). Let it sit for five or so minutes before spooning the cake onto a plate.
(*Someone sent me an a similar recipe that was the same except it had 3 tablespoons of chocolate chips and a splash of vanilla. I think that's a good idea. You should add those. I am going to next time. )
