Preheat oven to 350, or 325 if you have dark non-stick pan.
Prepare pan whichever way. ( I use butter, or even better, the spray).
In a bowl, cream together sugar and butter. Add the sifted flour and baking powder. Beat in eggs(one at a time). Stir in vanilla.Finally, stir in milk until batter is smooth. Bake for about 30-40 minutes, until cake springs back at touch.
