Ingredients
  

  • Ingredients
  • Graham Cracker Crust
  • 13 graham cracker sheets
  • ½ cup 1 stick salted butter, melted
  • 3 tablespoons white sugar
  • Pumpkin Mousse Filling
  • 8 oz full-fat cream cheese softened
  • 1 can 15 oz pure pumpkin puree
  • cup light brown sugar packed
  • teaspoons vanilla extract
  • 1 teaspoon pumpkin pie spice
  • 2 cups whipped topping Cool Whip or homemade
  • Homemade Whipped Cream
  • 2 cups heavy whipping cream
  • ½ cup powdered sugar
  • 1 teaspoon vanilla extract

Method
 

1. Prepare the Pie Dish

Lightly coat a 9-inch pie plate with nonstick spray so the crust releases easily later.

    2. Make the Graham Cracker Crust

    Place graham crackers into a food processor and pulse until they turn into fine crumbs. Add melted butter and sugar, then pulse again until the mixture resembles damp sand.

      3. Form the Crust

      Transfer the crumb mixture into the pie dish and firmly press it across the bottom and partway up the sides. A measuring cup or lightly damp fingers help create a smooth, compact crust.

        4. Chill the Crust

        Cover the pie dish with plastic wrap and place it in the freezer while preparing the filling.

          5. Mix the Pumpkin Filling

          In a large bowl or stand mixer, blend the softened cream cheese with pumpkin puree until smooth and creamy.

            6. Add Flavor

            Stir in brown sugar, vanilla extract, and pumpkin pie spice. Continue mixing until the filling looks silky and evenly combined.

              7. Fold in Whipped Topping

              Using a spatula, gently fold in the whipped topping until the mixture becomes airy and mousse-like.

                8. Fill the Pie

                Remove the crust from the freezer and spoon the pumpkin mousse into the crust. Spread it evenly across the surface.

                  9. Chill the Pie

                  Cover and refrigerate the pie for at least 6 hours or overnight so the mousse can fully set.

                    10. Prepare the Whipped Cream

                    When ready to serve, beat the heavy cream until stiff peaks form. Add powdered sugar and vanilla, mixing briefly until incorporated.

                      11. Finish the Pie

                      Spread the whipped cream over the chilled pumpkin mousse layer and serve.

                        Notes

                        How to Store Pumpkin Mousse Pie

                        This dessert should be kept refrigerated because of the mousse filling.
                        • Store the pie covered in the fridge for up to 3 days.
                        • Use plastic wrap or a pie dish with a lid to keep it fresh.
                        • Freezing is not recommended because the mousse texture can separate once thawed.
                        For best results, prepare the pie no more than 24 hours in advance and add the whipped cream topping right before serving.

                        Helpful Tips for the Best Pumpkin Mousse Pie

                        Prevent Sticky Crust Fingers

                        Lightly dampen your fingers or the bottom of a measuring cup before pressing the crust mixture into the pie dish. This keeps the crumbs from sticking.

                        Use Softened Cream Cheese

                        Cream cheese blends much easier when fully softened. Leave it at room temperature for a few hours or microwave it briefly in short intervals.

                        Keep Cream Very Cold

                        Chilled heavy cream whips faster and produces thicker, more stable whipped cream.

                        Chill the Pie Again After Topping

                        After adding the whipped cream layer, refrigerate the pie for another hour or two for cleaner slices.

                        Topping Ideas

                        FAQs

                        Can I make this pie ahead of time?

                         Yes! The pie actually benefits from chilling overnight, which helps the mousse set perfectly.

                        Can I use homemade whipped cream instead of Cool Whip?

                         Absolutely. Whipping heavy cream with powdered sugar creates a great substitute.

                        What if I don’t have a food processor?

                         Place graham crackers in a zip-top bag and crush them with a rolling pin until finely crumbled.

                        Can I use a store-bought graham cracker crust?

                         Yes, though a homemade crust tastes richer and holds together better.

                        Why didn’t my mousse set properly?

                         The pie likely needs more chilling time. Allow at least six hours in the refrigerator.
