Cheesecake
24 ounces cream cheese, softened and cut into chunks
1/2 cup granulated sugar
2 eggs
1/4 cup dairy sour cream
1 teaspoon vanilla extract

On bowl of electric mixer or in food processor fitted with metal blade, blend together cream cheese, sugar, eggs, sour cream and vanilla extract until smooth. Set aside.

Chocolate Cake
4 ounces unsweetened chocolate
1/2 cup (1 stick) butter
2 cup granulated sugar
4 eggs
2 teaspoons vanilla extract
1 1/2 cups all-purpose flour
Chocolate Glaze for sides (see below)
German Chocolate Topping (see below)
Whipped cream for garnish (optional)

In large microwave safe bowl, combine chocolate and butter. Microwave on HIGH (100%) power for 2 to 3 minutes, or until just melted. Cool slightly.

With fork, beat in sugar, eggs and vanilla extract until smooth. Add flour and mix until blended. Spoon into well-greased 9 1/2-inch springform pan, spreading evenly. Carefully, spread cheese mixture evenly over top of chocolate batter. Bake in preheated 425 degrees F oven for 15 minutes.

Reduce oven temperature to 350 degrees F and continue baking 55 to 60 minutes. Turn oven off, open oven door and let cake cool completely to room temperature in oven. Refrigerate until well chilled.

Remove sides from springform. Invert cake onto serving plate, so cheesecake is on bottom and chocolate cake is on top. Spread sides with Chocolate Glaze. Spread top evenly with German Chocolate Topping. Refrigerate until serving time. Garnish with whipped cream, if desired.
