A slightly smaller, lighter version:
2 tablespoons flour
1 tablespoon + 1 teaspoon sugar
1 teaspoon cocoa
1/4 teaspoon baking powder
pinch of salt
2 tablespoons milk
1 teaspoon oil
Chocolate chips, chopped nuts, a teaspoon of strawberry jam, or anything else that sounds yummy!
Mix dry ingredients in a small bowl, stir in milk and oil. Spray mug with nonstick cooking spray,
pour in cake batter and microwave on high for a minute to a minute and a half.
I adore this recipe because I have intolerances to both eggs and milk, so its rare for me to find a cake recipe that I can eat. I substitute soy milk for the milk.
