3. In medium bowl, beat sweet potatoes, 1 tablespoon butter, 1 teaspoon cinnamon, the nutmeg and vanilla with electric mixer on low speed until blended; set aside. In large bowl, beat cream cheese and 1 cup sugar on medium speed about 1 minute or until smooth. Beat in sweet potato mixture on low speed about 1 minute or until blended. Beat in eggs, one at a time. Spoon batter into crust in pan.
4. Place springform pan in larger pan on oven rack.
5. Pour very hot water into larger pan to one-third the height of springform pan.
6. Bake cheesecake about 1 hour 30 minutes, adding very hot water to larger pan as needed, until center is set.
