Ingredients

 * Cake :::
 * 9 eggs (room temperature)
 * 1 1/2cups sugar
 * 12 tablespoons butter (softened)
 * 2 cups all-purpose flour
 * 1 1/2teaspoons baking powder
 * 1 cup milk
 * 1 teaspoon vanilla extract
 * 1 teaspoon cream of tartar
 * Three Milks :::
 * 2 cups heavy cream
 * 1 five-ounce can (5/8cup) evaporated milk
 * 1 fourteen-ounce can (7/8cup) sweetened condensed milk
 * Cream Icing :::
 * 2 cups heavy cream
 * 1/3cup sugar

Directions

 * 1) Preheat oven to 350 degrees.
 * 2) Separate egg yolks and whites, keeping whites at room temperature.
 * 3) In bowl of an electric mixer, cream sugar and butter together until pale yellow and fluffy.
 * 4) Add egg yolks and beat until fluffy again, 2 to 3 minutes on medium-high speed.
 * 5) In a separate bowl combine flour and baking powder.
 * 6) In a third bowl mix milk and vanilla.
 * 7) Alternately add the flour mixture and the milk mixture to the butter mixture (a fourth at a time) until all are combined.
 * 8) Beat until smooth after each addition.
 * 9) Beat egg whites with cream of tartar until soft peaks form and, using a large spatula, gently but thoroughly fold into flour-and-butter mixture.
 * 10) Grease bottom of a 9- by 13-inch metal baking pan.
 * 11) Pour in batter and bake for approximately 25 minutes, until golden brown.
 * 12) Allow to cool. (May also be baked in an 11.5- by 17.5-inch sheet pan for 20 minutes; this size rises very evenly, helpful for inexperienced cooks.)
 * 13) MILK MIXTURES :::
 * 14) Stir the milks together thoroughly; do not beat. Do not refrigerate canned milks before using.
 * 15) CREAM ICING :::
 * 16) Whip cream and sugar together until stiff.
 * 17) When cake is cool, slice or peel off the thin top crust.
 * 18) Ice sides first, creating a small lip on top to catch milk mixture.
 * 19) Pour milk mixture evenly over top of cake (if necessary, poke holes in cake with a knife or toothpick to facilitate soaking; you will probably need only 3/4of mixture).
 * 20) Finish icing top.
 * 21) Refrigerate.
