Even young children can make this cake, with a little help from Dad. Combine first four ingredients in a bowl, blend with a mixer at low speed, then beat at medium speed for about 6 to 8 minutes. Line three 9-inch cake pans with rounds of waxed paper and pour batter into pans. Bake at 350 degrees F for 25 to 30 minutes, or until a toothpick comes out clean. Cool in pans for 15 minutes, turn out on a rack, and frost when cool.
