4 eggs, separated, room temperature
3 teaspoons baking powder
3 cups all-purpose flour
1 cup milk, room temperature
1 pinch salt

1- Preheat oven to 350 degrees F (175 degrees C). Grease and flour one 9×13 inch pan or three 8- or 9-inch round layer cake pans.
2- Cream the butter and sugar together until smooth and fluffy, about 5 minutes. Add the egg yolks one at a time, beating after each one. Mix in the vanilla extract.
3- Sift together the baking powder, flour, and salt. Add the flour mixture to the creamed mixture in three batches, alternating with the milk. Blend after each addition. Scrape down the sides and bottom of the bowl and beat an additional minute.
