This is a recipe for my favorite chocolate cake. It comes, mostly unaltered, from the treasure trove of culinary art that is Ann Brooks. If you dislike this cake, you are objectively a bad person.
This recipe has 3 distinct components: the cakes, the frosting, and the whipped cream.
Make The Cakes
Mix cocoa, egg yolk and 1 cup milk. Heat over low burner. Stir until smooth and thickened. Cream butter until light. Add sugar vanilla, eggs and egg white. Blend in cocoa mixture.Be sure cocoa mixture isn't too hot as it can make the eggs cook. Add dry ingredients with remaining milk. Line two 9" pans with greased wax paper. Pour batter into pans. Bake at 350°F for about 25 minutes.
Cool cake a few minutes. Invert and remove wax paper.
When ready to assemble, cut each cake in half horizontally so you have 4 cakes.
Mix in the butter and cream cheese, then add the cocoa, salt and vanilla. While mixing, alternate adding the sugar and the light cream.
Beat the heavy cream, adding in ¼ cup 10X sugar and 1 tsp vanilla.
From the bottom, up: cake, thin layer frosting, whipped cream. Repeat until the top. The top layer gets only frosting, no whipped cream. The frosting is usually thin and may try to run. Get it thick enough to stick on, but let it drizzle a bit down the sides.
The cake must be refrigerated and gets better if left there a few hours. You may have to put a couple long toothpicks or bamboo skewers in it if the cakes come out lopsided so that the layers don't slide around on each other.
