To prepare a triple chocolate and vanilla cheesecake baked goods recipe, first you need to prepare the ingredients. First, you'll need the following ingredients: Preheat the oven to 350?F (176?C) and grease and flour two 9-inch springform pans. Line the bottom and sides of each pan with foil and set aside. In the bowl of an electric mixer fitted with the paddle attachment, cream together the butter and sugar until light and fluffy. Gradually add the egg yolks and beat until stiff peaks form. Fold in the vanilla and chocolate chips until combined. Pour the batter into the prepared pan and bake for 35 to 40 minutes or until the center of the cake springs back when you touch it. Let the cakes cool before removing them from the pan.
