* You can substitute light cream cheese.
Beat cream cheese, sugar and vanilla at medium speed until well blended. Blend in 2 eggs. Stir in chocolate chips then pour batter into graham cracker pie crust.
(you may sprinkle quarter cup mini semi-sweet chocolate chips on top if you desire)
Bake at 180ºC for 40 min, or until center is almost set. Cool.
For best results refrigerate for 3 hours.
