Step‑by‑Step Instructions for Pumpkin Mousse Pie
Step 1: Prepare the Crust
Start by processing 2 cups of gingersnap cookies into fine crumbs using a food processor. In a mixing bowl, combine the crumbs with 6 tablespoons of melted unsalted butter and a pinch of salt, blending until it resembles wet sand. Press this mixture firmly into the bottom and up the sides of a 9-inch pie plate. Pop it in the refrigerator for at least 30 minutes to firm up.
Step 2: Make the Mousse
In a large bowl, beat 8 ounces of room temperature cream cheese with 1 cup of powdered sugar using an electric mixer until smooth and creamy, about 2-3 minutes. Gradually mix in 1 cup of pumpkin puree, 1 teaspoon of vanilla extract, and 2 teaspoons of pumpkin pie spice. Ensure everything is well combined and silky, creating a rich, velvety filling for the Pumpkin Mousse Pie.
Step 3: Whip the Cream
In a separate bowl, take 1 ½ cups of very cold heavy whipping cream and whip it using an electric mixer until soft peaks form, which will take about 3-4 minutes. Watch closely, as over-whipping can lead to a grainy texture. This whipped cream will add lightness to your mousse, so keep it nice and airy.
Step 4: Combine Mixtures
Gently fold the whipped cream into the pumpkin mixture in batches using a rubber spatula. Start with one-third of the whipped cream to lighten the pumpkin mix, then carefully fold the remaining whipped cream until no white streaks remain. This step is crucial to maintaining the airy texture of your Pumpkin Mousse Pie filling.
Step 5: Assemble Pie
Carefully pour the exquisite pumpkin mousse into the chilled gingersnap crust, smoothing the top with a spatula. Cover the pie with plastic wrap and place it in the refrigerator to chill for at least 3 hours, or ideally overnight. During this time, the flavors meld and the pie sets perfectly for slicing.
Step 6: Prepare the Topping
When ready to serve, whip together 1 cup of additional heavy cream, 2 tablespoons of powdered sugar, 1 tablespoon of maple syrup, and a sprinkle of ground cinnamon. Beat until soft-stiff peaks form, making sure not to over-whip. This luscious topping will complement the creamy texture of your Pumpkin Mousse Pie beautifully.
Step 7: Serve
Spread the whipped cream topping evenly over the chilled pumpkin mousse and slice the pie into wedges. You can further garnish with a dusting of cinnamon or nutmeg for a festive touch. Each slice of this Pumpkin Mousse Pie promises a delightful contrast of flavors that will surely impress all who partake!

Make Ahead Options
These Easy No-Bake Pumpkin Mousse Pies are ideal for those busy weeks when meal prep is essential! You can prepare the gingersnap crust up to 24 hours in advance; just press it into the pie plate and refrigerate it until you're ready to fill it. The pumpkin mousse can also be made ahead and stored in an airtight container in the refrigerator for up to 3 days. To maintain the pie's delicious texture, remember to cover it tightly with plastic wrap before chilling and wait to add the whipped cream topping until just before serving. When you're ready to enjoy, simply whip the cream and spread it on top for that heavenly finish—saving you time without sacrificing flavor!

Pumpkin Mousse Pie Recipe FAQs
How do I choose the right pumpkin puree?
Absolutely! For the best flavor, look for 100% pure pumpkin puree rather than pumpkin pie filling, which contains added sugars and spices. If you're using fresh pumpkin, opt for small, sugar pumpkins, which have a sweeter taste and smoother texture. To make your own puree, simply roast the pumpkin halves, scoop out the flesh, and blend until smooth.
What’s the best way to store leftover Pumpkin Mousse Pie?
Store your Pumpkin Mousse Pie in the refrigerator, covered tightly with plastic wrap, for up to 3-4 days. This keeps the mousse and crust fresh and ready to enjoy any time. If you anticipate having some left after the first day, I'd recommend dividing the pie into individual slices for easier access and to maintain its crisp crust!
Can I freeze Pumpkin Mousse Pie?
Yes, you can freeze your Pumpkin Mousse Pie! Carefully wrap it in plastic wrap and then in aluminum foil to protect it from freezer burn, and place it in the freezer for up to 1 month. When you're ready to enjoy it, thaw the pie overnight in the refrigerator. After thawing, the whipped topping may need to be re-whipped for the best texture.
What if my mousse didn’t set properly?
If your Pumpkin Mousse Pie didn’t set, it could be due to the cream not being whipped to stiff peaks or not allowing enough chilling time. To troubleshoot, gently re-whip the cream and fold it into the mixture again, then refrigerate for an additional hour or so. If time allows, you may consider reinserting it into the refrigerator for longer to allow it to firm up beautifully.
Are there dietary considerations for this recipe?
Certainly! This Pumpkin Mousse Pie is vegetarian-friendly; however, if you’re catering to gluten sensitivities, make sure to use gluten-free gingersnap cookies. Also, for a dairy-free version, substitute cream cheese and heavy cream with coconut cream and dairy-free cream cheese alternatives. Just ensure the texture remains airy and smooth!
Can I make this pie a day in advance?
Very much so! In fact, making the Pumpkin Mousse Pie a day ahead often enhances the flavors and allows the pie to set perfectly. Just remember to cover it with plastic wrap to prevent any absorption of odors from the fridge. This also saves you time on the day of your gathering, letting you enjoy the festivities instead of being stuck in the kitchen!
