Preheat oven to 350°F if using a silver 9-inch springform pan (or to 325°F if using a dark nonstick 9-inch springform pan). Mix crumbs, 3 Tbsp. sugar and the butter; press firmly onto bottom of pan. Bake 10 min.

Beat cream cheese, 1 cup sugar, the flour and vanilla in large bowl with electric mixer on medium speed until well blended. Add melted chocolate and sour cream; mix well. Add eggs, one at a time, mixing on low speed after each addition just until blended. Pour over crust.

Bake 1 hour 5 min. to 1 hour 10 min. or until center is almost set. Run knife 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.
