Cake
1 cup vegetable shortening
1 cup granulated sugar
1 whole egg
3 egg yolks
1 1/2 cups sifted cake flour
2 teaspoons baking powder
1 pinch salt
1/2 cup milk
1 teaspoon vanilla
3 egg whites
Icing
3 ounces unsweetened chocolate
1 (14 ounce) can sweetened condensed milk
1/2 cup unsalted butter, cut into 8 pieces
1 egg yolk, beaten
1 1/2 teaspoons vanilla

Preparation

To make cake, preheat oven to 350\u00b0F
In a large bowl, beat shortening until light.
Slowly beat in sugar.
Add egg and egg yolks, one at a time, beating well after each addition.
Sift flour with baking powder and salt.
Add to batter in 3 parts, alternating with 3 parts milk.
Stir in vanilla.
Beat egg whites until stiff.
Fold into batter.
Pour batter into two buttered and floured 8-inch round cake pans.
Bake for about 25 minutes, until a toothpick inserted in center comes out clean.
Cool on a wire rack before icing.
To make icing, in top of a double boiler over simmering water, melt chocolate and stir in condensed milk. Beat until smooth.
Stir in butter, one piece at a time, stirring after each addition. Stir in egg yolk and vanilla. Beat until smooth and thick. (If the icing becomes too thick, thin with a little hot water.).
