Directions

1. Preheat oven to 300 degrees F if using silver 9-inch springform pan (or to 275 degrees F if using dark nonstick 9-inch springform pan). Mix cookie crumbs and butter; press firmly onto bottom of pan. Set aside.
2. Beat cream cheese, sweetened condensed milk and vanilla in large bowl with electric mixer on medium speed until well blended. Add chocolate; mix well. Add eggs, one at a time, mixing on low speed after each addition just until blended. Pour over crust.
3. Bake 1 hour 5 min. to 1 hour 10 min. or until center is almost set. Run knife or metal spatula around rim of pan to loosen cake; cool before removing rim of pan. Refrigerate at least 4 hours or overnight. Store leftover cheesecake in refrigerator.
