2 teaspoons vanilla extract
Equipment

Directions
Make crust: Preheat oven to 350F. Butter an 8-inch springform pan. Cover outside of pan with 2 layers of foil. Stir together all crust ingredients. Press into bottom and up sides of pan.
Bake for 10 minutes.
Let cool on a rack.
Make filling: With an electric mixer on medium speed, beat cream cheese and both sugars until light. Beat in eggs and yolks, 1 at a time. Beat in pumpkin, sour cream and vanilla. Reduce speed to low; beat in flour and spice.
Pour into crust.
Place cheesecake in a large roasting pan; fill pan with 2 inches of hot water.
Bake until cake is set around edges but still slightly jiggly when lightly shaken (cheesecake will firm as it cools), 55 to 65 minutes.
Transfer to a wire rack and let cool to room temperature. Cover and chill for at least 10 hours or up to 2 days.
