4 eggs
2 cups granulated sugar
2 1/4 cups all-purpose flour
2 1/4 teaspoons baking powder
1 teaspoon vanilla extract
1 1/4 cups milk
10 tablespoons butter or margarine

In a mixing bowl, beat eggs at high speed until thick, about 5 minutes. Gradually add sugar, beating until mixture is light and fluffy.

Combine flour and baking powder; add to batter with vanilla extract and beat at low speed until smooth.

In a saucepan, heat milk and butter just until the butter melts, stirring occasionally. Add to batter, beating until combined. Pour into a greased 13 x 9-inch baking pan. Bake at 350 degrees F for 30 to 35 minutes or until cake tests done. Cool on a wire rack.
