Easy Chocolate Lover's Cheesepie

I made this for Valentine's Day.  It is fast, easy, and really delicious!  It's rich, but not over the top.  I have had this recipe for years.  It's from Hershey's. 

3 packages cream cheese (8 oz ea), softened (I use the 1/3 less fat)

3/4 c sugar

3 eggs

1 t vanilla extract

2 c (12 oz pkg) Hershey's Mini Semi-Sweet Chips, divided

1 extra-serving-size packaged graham cracker crust (9 oz)

(I made my crust, I like homemade better.  I used a deep dish 9" pie plate)

2 T whipping cream

1. Heat oven to 450.

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

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

4. Place remaining 1/3 c chips and whipping cream in a small bowl.  Microwave at high 20-30 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 pie.  Serves 10.
