PREHEAT oven to 325°F if using a silver springform pan (or 300°F if using a dark nonstick springform pan). Mix crushed cookies and butter; press onto bottom of 9-inch springform pan. Bake 10 minutes.
BEAT cream cheese, sugar and vanilla with electric mixer on medium speed until well blended. Add eggs, 1 at a time, mixing on low speed after each addition just until blended. Gently stir in quartered cookies. Pour over crust.
BAKE 1 hour 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 4 hours or overnight. Garnish with additional cookies, if desired.
