BEAT cream cheese in medium bowl with electric mixer until fluffy; gradually beat in sweetened condensed milk until smooth. Add egg and vanilla; mix well.
TOSS chocolate chips with flour; stir into cream cheese mixture. Pour into crust.
Bake 35 minutes or until center springs back when lightly touched. Cool and top with Chocolate Glaze and chocolate curls (optional). Serve chilled.
MELT chocolate chips with cream in small heavy saucepan; cook and stir until thickened and smooth. Immediately spread over cheesecake.
To prevent chocolate chips from floating down to bottom of pie, remove cheesecake from oven after 5 to 10 minutes, sprinkle chocolate chips over pie; continue to bake for remaining baking time. (Be careful when handling cheesecake, pie pan will be very hot.)
*To make chocolate shavings, start with a good quality chocolate in block form. Using vegetable or potato peeler, hold chocolate with paper towel; pass vegetable peeler over narrowest side of chocolate block. The chocolate will curl up like wood shavings. Store in covered container in refrigerator until needed.
