East Chocolate Lover's Cheesepie

3 pkgs (8 oz each) cream cheese, softened
3/4 cup sugar
3 eggs
1 teaspoon vanilla extract
2 cups (12 oz pkg) Hershey's mini chips, semi-sweet chocolate, divided
1 extra-serving-size packaged graham cracker crumb crust (9 oz)
2 tablespoons whipping cream

Heat oven to 450.

Beat cream cheese and sugar in large bowl with mixer until well blended. Add eggs and vanilla; beat well. Stir in 1-2/3 cups small chocolate chips; pour into crust.

Bake 10 minutes. Without opening oven door, reduce temperature to 250; continue baking 30 minutes or just until set. Remove from oven to wire rack. Cool completely. Cover; refrigerate until thoroughly chilled.

Place remaining 1/3 cup chips and whipping cream in small microwave-safe bowl. Microwave at high 20 to 30 seconds or just until chips are melted and mixture is smooth when stirred. Cool slightly; spread over top of cheesepie. Refrigerate 15 minutes or until topping is set. Cover; refrigerate leftover cheesepie.
