1/4 cup butter (softened)
1/4 cup sugar
2 cups SR flour
1/2 cup milk
Cream the butter and sugar together (if using raw sugar, as I often do, it won’t cream properly, but that’s ok), then beat in one egg, half the flour and milk, then when that has combined beat in the other egg, and the rest of the flour and milk.
You can add vanilla or other flavourings, and use this as a base for making cakes or cupcakes.
