Philadelphia 3-Step Chocolate Chip Cheesecake

I make this every year for hubby's birthday and it is very yummy.

2 pkg. (8 oz. each) PHILADELPHIA Cream Cheese, softened
1/2 cup sugar
1/2 tsp. vanilla
2 eggs
3/4 cup miniature semi-sweet chocolate chips, divided
1 ready-to-use graham cracker crumb crust (6 oz.)

1) Heat oven to 350°F.

2) Beat cream cheese, sugar and vanilla in large bowl with mixer until blended. Add eggs; mix just until blended. Stir in 1/2 cup chocolate chips.

3) Pour into crust. Sprinkle with remaining 1/4 cup chocolate chips.

4) Bake 40 min. or until center is almost set. Cool. Refrigerate 3 hours.
