These pumpkin cheesecake bars are the perfect fall dessert. The crust is made with gingersnap cookies and melted butter, and the cheesecake filling is made with cream cheese, pumpkin puree, and warm spices like cinnamon, nutmeg, and ginger. The bars are topped with a dollop of whipped cream and a sprinkle of cinnamon. They're creamy, spicy, and delicious.
