PREHEAT oven to 325°F if using a silver springform pan. (Or, preheat oven to 300°F if using a dark nonstick springform pan.) Mix crumbs, 3 Tbsp. sugar and butter; press firmly onto bottom of 9-inch springform pan. Bake 10 min.
PLACE cream cheese, 1 cup sugar, flour and vanilla in large bowl. Beat with electric mixer on medium speed until well blended. Add sour cream; mix well. Add eggs, 1 at a time, mixing on low speed after each addition just until blended. Pour over crust.
*easy to add additional flavour, like a quarter cup of Bailey's Irish Cream. Mmmmm..... :)
