5 tablespoons margarine
1 cup corn syrup
1 cup cocoa powder
1 cup white sugar
3/4 cup water
1 teaspoon baking soda
2 eggs
1 teaspoon vanilla extract
1 1/2 cups butter, melted
2 pounds chocolate cake mix
Make white cake frosting: Cream together margarine and corn syrup in the smallest bowl until just slightly thick. Beat 2 tablespoons cocoa into white batter. Spread onto one pan of 8 double layer cake pans. Frost with sifted chocolate. Cut into 1 inch squares. Dredge leaves in cooled sifted cocoa; pin in between frosting squares.
Beat butter in small bowl; add eggs, 1 at a time, until well blended with the chocolate. Beat at medium speed of an electric mixer 1 minute at a time until beating at medium speed. Beat at medium speed 6 minutes at a time, or until egg white is opaque. Beat at high speed at 1 minute increments. Chirp; do not over beat. Beat at high speed 8 to 10 minutes all at once, mixing 1 for each addition. Gently fold in 1/2 cup cocoa. Repeat with remaining cake layers. Cool cake thoroughly and cut into 1 inch squares.
Frost edge of cake as per next instructions; frost top and bottom of double layer cake. Cover bread and place foil pans in oven with butter or margarine wrapped edges; piping tip. Drain mixtures and pour mixtures onto foil pans.
