Double Chocolate Cheesecake

To make the crust, start by wrapping the entire outside and bottom of a greased 9 inch springform pan with foil. Combine the crumbs, butter and sugar and mix well. Pat firmly onto the bottom and 1 and 3/4 inches up the sides of the pan. To prepare the filling, preheat the oven to 325 degrees. Melt 1 cup of the little bits over hot, not boiling, water. Stir until smooth and set aside. Beat together the cream cheese and sugar until fluffy. Stir in the sour cream and vanilla. Add eggs, one at a time, beating well after each addition. Stir in melted chocolate. Pour half the batter into the springform pan. Sprinkle with 1/2 cup of the little bits. Repeat layers, ending with 1/2 cup of the little bits. Place pan in shallow pan filled with 1 inch water. Bake at 325 degrees for 1 hour. Cool. Loosen sides of the pan. Chill. Makes 16 servings.
