Crust
10 – 12 oz of store bought gingersnaps
½ cup chopped pecans
¼ cup packed light brown sugar
2 to 3 tablespoons granulated sugar (optional, depending on the sweetness of your gingersnaps)
6 to 8 tablespoons melted salted butter
Caramel (homemade or store bought)
Filling
3 8oz packages of cream cheese, at room temperature
1 15 oz can packed pumpkin puree (pure pumpkin, not pumpkin pie filling)
¼ cup sour cream
3 eggs + 1 egg yolk
1 ½ cups granulated sugar
1 ½ teaspoons cinnamon
½ teaspoon nutmeg
½ teaspoon ground ginger
½ teaspoon salt
2 tablespoons all-purpose flour
1 tsp vanilla extract
Prep
Preheat oven to 325 degrees. Grease a 9 or 10 inch springform pan. If you want to remove the bottom of your springform pan before serving, place a round of parchment paper slightly larger than the pan on the bottom of the pan before locking on the sides.
Make the crust
Pulse gingersnaps in a food processor (in batches, if needed) until crushed to fine crumbs. Place 1 ½ cups gingersnap crumbs in a medium bowl. Combine crumbs with pecans, brown sugar, granulated sugar (if using), and 6 tablespoons of the melted butter. Add additional butter, 1 tablespoon at a time, if needed to moisten crust. Press crust onto bottom and sides of prepared springform pan. Spread a layer of caramel over the crust. Chill crust in refrigerator for at least 30 minutes before baking.
Make the filling
Beat the cream cheese with an electric mixer on medium speed until smooth. Add the pumpkin, sour cream, eggs, sugar, spices and salt and beat on low speed until well-combined. Add the flour and vanilla and beat just until incorporated. Pour filling into prepared crust.
Bake and Cool
Place the cheesecake on a foil-lined baking sheet on a rack in the upper half of the preheated oven. To prevent cracking, place a water bath (a large pan filled with boiling water) directly below the rack the cheesecake is on. Bake for 90 minutes or until filling is set but still jiggly in the center. Turn off the oven and open door halfway. Let cheesecake cool in oven for about an hour. Transfer cheesecake to a rack and cool in pan until room temperature. Then cover cheesecake and cool in the refrigerator at least four hours. Carefully remove sides of springform pan before cutting and serving.
Make ahead
The cheesecake can be made up to two days in advance and stored in the refrigerator. Freeze cheesecake if storing longer than two or three days.
