For the cake, cream the butter and sugar in the bowl of an electric mixer fitted with the paddle attachment on high speed for 5 minutes until light. Reduce the speed to low and add the eggs one at a time, then the vanilla and sour cream. In a separate bowl, sift together the flour, baking powder, baking soda and salt. With the mixer on low speed, add the flour mixture to the batter until just combined. Stir with a spatula to make sure mixture is combined.
