This seasonal cheesecake is a favorite in the fall. The crust is made with gingersnap cookies and the filling is a mixture of cream cheese, pumpkin puree, and warm spices like cinnamon, nutmeg, and ginger. The cheesecake is baked until it's set and then chilled until it's firm. It's often served with a dollop of whipped cream and a sprinkle of cinnamon.
