Peanut Butter Chocolate Chip Cheesecake

For Valentine's Day I made a Peanut Butter Chocolate Chip Cheesecake. It was so yummy, I thought I would share the recipe.

Graham cracker crust (recipe follows)
3 pkgs 8oz cream cheese, softened
¾ cup sugar
1 2/3 cup (10 oz. package) Peanut Butter Chips
¼ cup milk
4 eggs
1 teaspoon vanilla extract
1 ½ cups mini chips

Graham cracker crust: heat oven to 325o. In small bowl, stir together 1 cup graham cracker crumbs (I use choc. Graham crackers), 3 tablespoons sugar and 3 tablespoons melted butter or margarine. Press mixture onto bottom of 9-inch spring form pan. Bake 10 minutes. Remove from oven.Heat oven to 450o. In large mixer bowl, combine cream cheese and sugar; beat on medium speed of electric mixer until smooth. In small microwave-safe bowl, place peanut butter chips with milk. Microwave at HIGH (100%) 1 minute; stir. If necessary, microwave at HIGH an additional 15 seconds at a time, stirring after each heating, just until chips are melted when stirred. Blend peanut butter chip mixture into cream cheese mixture. Add eggs, one at a time, mixing well after each addition. Stir in vanilla and mini chips. Pour mixture over crust. Bake 10 minutes. Reduce oven temp to 250o; continue baking 40 minutes. Remove from oven to cooling rack; loosen cake from rim of pan. Cool completely; remove rim. Cover; refrigerate leftovers.
