Prepare the Crust: Begin by preheating your oven to 350°F (175°C). In a medium-sized bowl, mix 1 1/2 cups of crushed ginger snap cookies with 1/4 cup of melted unsalted butter. Press this mixture firmly into the bottom of a lined 9x13 inch baking pan. Bake for 8 minutes and then set aside to cool.
Create the Cream Cheese Layer: In a large mixing bowl, beat 16 oz of softened cream cheese until smooth and creamy. Gradually add 1 cup of sugar, 2 eggs, and 1 teaspoon of vanilla extract, continuing to beat until well combined. Spread this buttery cream cheese mixture over the cooled ginger snap crust.
Prepare the Pumpkin Mixture: In a separate bowl, combine 1 cup of pumpkin puree with 1/2 teaspoon of cinnamon, 1/4 teaspoon each of nutmeg, ginger, and cloves. Spread this fragrant pumpkin mixture evenly over the cream cheese layer.
Bake and Cool: Bake the assembled layers in the preheated oven for 35-40 minutes, or until the bars are set and slightly firm to the touch. Allow them to cool to room temperature before refrigerating for at least 2 hours to allow the flavors to meld and the layers to firm up.
Serving: Just before serving, top your pumpkin bars with a generous layer of whipped cream and a sprinkle of crushed ginger snaps. Slice into bars and enjoy the perfect fall dessert experience.
