Preparation

Heat the oven to 350° F (180° C/Gas 4) . Line bottoms of three 8-inch layer pans with parchment paper or wax paper.

Separate 3 of the eggs.

Put one yolk in a separate bowl.

Put two of the yolks in a bowl with the remaining whole egg.

Set the whites aside. 

In a saucepan over medium low heat, combine cocoa, 3/4 cup of the granulated sugar, 1 of the egg yolks, and milk. Cook, stirring constantly to prevent sticking, until thickened.

Cool.

In a mixing bowl with electric mixer, cream the 1/2 cup of softened butter until light and fluffy; add remaining 1 cup of granulated sugar, beating until well blended. Add the whole egg and 2 egg yolks; mix well.

Combine the flour, baking powder, baking soda, and salt; stir or sift together to blend. Stir  dry ingredients into the batter, alternating with the sour cream. Add vanilla and cocoa mixture and blend thoroughly

Beat the 3 egg whites until stiff; fold into cake batter.

Divide the batter evenly among the three prepared baking pans.

Bake 30 to 35 minutes, or until a toothpick inserted into the center of the cakes comes out clean.

Turn out onto racks and peel off paper. Cool.

Frost with the included chocolate butter frosting or your favorite frosting, such as Creamy Chocolate Cream Cheese Frosting or Chocolate Sour Cream Frosting.

Chocolate Butter Frosting

Cream softened butter; gradually add sifted confectioners' sugar. Add dash of salt, vanilla extract, melted chocolate, and about 3 tablespoons of cream.

Beat until smooth and spreading consistency, adding more cream if necessary.
