I have just the thing! I use this as my base for tons of different cakes, changing up the flavours. It's also the base for my famous mojito cupcakes.

Quick Plain Cake
CAKE:
1/2c sugar
1 1/2c flour
1/4 tsp salt
2 tsp baking powder
1 tsp flavouring (vanilla, cinnamon, rum flavouring, booze, whatever)
1/4c melted butter
1 beaten egg
1c milk (milk past its date preferred)
Preheat your oven to 350F or 180C.
Mix all the dry stuff together in a big bowl (if your flavouring is dry, put it in here, if it's wet, put it with the wet stuff).
Melt the butter in the microwave and add the beaten egg to it. Add that to the dry ingredients, stirring in the milk and rum until smooth.
Split the batter between 12 lined cupcake wrappers or one 9" cake pan. Bake for 10-12 minutes, or until the sides pull away and are golden brown (the tops should be spongey to the touch) or a skewer comes out clean. When done, remove to a wire rack and wait until they're completely cool before you attempt to ice them!
