Chocolate Swirl Cheesecake

Preheat oven to 375 degrees F. For crust, in a bowl combine crushed graham crackers, walnuts, the 1 tablespoon sugar, and, if desired, the cinnamon. Stir in melted butter. Press the crumb mixture onto the bottom and about 2 inches up the sides of a 9-inch springform pan; set aside.

For filling, in a large mixing bowl beat cream cheese, the 1 cup sugar, the flour, and vanilla with an electric mixer until combined. Beat in milk until smooth. Stir in eggs.

Pour filling into crust-lined pan. Pour filling into crust-lined pan. Dot with melted chocolate and use a thin metal spatula to marble. Place pan in a shallow baking pan (see optional Water Bath Method, below). Bake for 35 to 40 minutes or until a 2-1/2-inch area around the outside edge appears set when gently shaken.

Cool in pan on a wire rack for 15 minutes. Using a small sharp knife, loosen the crust from sides of pan; cool for 30 minutes. Remove the sides of the pan; cool cheesecake completely on rack. Cover and chill at least 4 hours before serving. If desired, serve with Raspberry Sauce or fresh rasberries. Makes 12 servings.
