How to Make Pumpkin Mousse Pie
Whipping up this incredible Pumpkin Mousse Pie is a breeze, truly! You’ll begin by pressing together a simple graham cracker crust, a sweet and crunchy base that requires no baking at all. Next, we’ll gently bloom some gelatin to ensure our mousse sets beautifully. Then, it’s all about creating that luscious, spiced pumpkin mousse base before folding in billows of freshly whipped heavy cream for that irresistible airy texture. Finally, assemble everything in your crust, chill until firm, and get ready to garnish and serve a show-stopping dessert!

Ingredients
Equipment
Method
- In a medium bowl, combine graham cracker crumbs and granulated sugar. Pour in the melted butter and stir until the crumbs are evenly moistened.
- Press the mixture firmly and evenly into the bottom and up the sides of a 9-inch pie plate. Use the bottom of a glass or your knuckles to get a compact crust. Place the pie plate in the refrigerator to chill while you prepare the filling, for at least 15 minutes.
- In a small bowl, sprinkle the unflavored gelatin powder over 1/4 cup of cold water. Let it sit for 5 minutes to “bloom” (it will thicken and become spongy).
- Heat the gelatin mixture gently in a small saucepan over low heat, or in the microwave for 10-15 seconds, stirring until the gelatin is completely dissolved and clear. Do not boil. Set aside to cool slightly, but ensure it remains liquid.
- In a large mixing bowl, using an electric mixer, beat the softened cream cheese until smooth and creamy, about 1-2 minutes.
- Add the pumpkin puree, powdered sugar, pumpkin pie spice, and vanilla extract to the cream cheese. Beat until well combined and smooth, scraping down the sides of the bowl as needed.
- Gradually pour the slightly cooled, dissolved gelatin into the pumpkin mixture while the mixer is running on low speed. Beat until fully incorporated.
- In a separate clean, large bowl, pour the 1.5 cups of very cold heavy cream. Using an electric mixer, beat on medium-high speed until stiff peaks form. Be careful not to overbeat, or it will turn granular.
- Gently fold the whipped cream into the pumpkin mixture in two additions using a rubber spatula. Fold until just combined and no streaks of whipped cream remain. Do not overmix, as this can deflate the mousse.
- Pour the pumpkin mousse filling into the chilled graham cracker crust. Spread evenly with a spatula.
- Cover the pie loosely with plastic wrap and refrigerate for at least 3 hours, or preferably overnight, until the mousse is firmly set.
- Before serving, if desired, prepare a fresh whipped cream garnish. In a clean bowl, beat 1/2 cup cold heavy cream with 1 tbsp powdered sugar until stiff peaks form. Pipe or dollop onto the pie slices.
- Lightly dust with a sprinkle of cinnamon or pumpkin pie spice. Slice and serve cold.
Notes
Making a no-bake pie might seem straightforward, but a few little tricks I’ve learned over the years can elevate your Pumpkin Mousse Pie from simply good to absolutely unforgettable.
First, ensure your cream cheese is truly at room temperature. This makes for a silky-smooth pumpkin base with no lumps, ensuring every spoonful is pure bliss. I always take mine out an hour or two before I plan to start.
When whipping your heavy cream, make sure both the cream and your mixing bowl are very cold. This helps the cream whip up faster and hold its peaks longer, giving your mousse that wonderfully light and airy texture.
My Secret Trick: I always chill my mixing bowl and whisk attachment in the freezer for about 10-15 minutes before whipping heavy cream. It makes all the difference for achieving perfectly stiff peaks every time!
And don’t rush the chilling process! This pie needs ample time to set properly, so giving it a full 4-6 hours, or even better, overnight, ensures a perfectly firm slice of Pumpkin Mousse Pie. Trust me, it’s worth the wait!
Fun Variations for Pumpkin Mousse Pie
One of the things I adore about baking is how easily you can make a recipe your own, and this delightful Pumpkin Mousse Pie is no exception! It’s a fantastic canvas for a little creativity, allowing you to tailor it to your mood or your guests’ tastes.
Crust Creations
While the classic graham cracker crust is wonderful, consider a gingersnap crust for an extra autumnal spice kick. Or, for a touch of elegance, a chocolate wafer crust would be divine, especially with the creamy pumpkin. My sister always asks me to use a crushed Biscoff cookie crust when I make this pie!
Flavor Twists
Swirl in a tablespoon of caramel sauce into the pumpkin mousse base for a luscious caramel-pumpkin delight. A dash of maple extract alongside the vanilla can also enhance that cozy fall feeling. For a bolder spice, add a pinch of ground ginger or a hint of cardamom.
Topping Temptations
Beyond whipped cream, consider a sprinkle of toasted pecans or candied walnuts for added texture. A drizzle of dark chocolate or white chocolate ganache could also turn this into an even more decadent treat. A friend loves when I top it with a light dusting of cocoa powder for a sophisticated finish.
What to Serve With Pumpkin Mousse Pie
This lovely dessert, especially a creamy Pumpkin Mousse Pie, is truly a star on its own, but sometimes a little accompaniment can make the experience even more delightful. Think of it as creating a complete sweet moment!
For a simple yet classic pairing, a dollop of freshly whipped cream is always a winner. You could even infuse it with a touch of maple syrup or cinnamon for an extra layer of flavor. I love serving it with a scoop of homemade vanilla bean ice cream; the contrast in temperature and texture is simply divine.
If you’re enjoying this pie on a chilly evening, a warm mug of spiced chai latte or a steaming cup of rich coffee makes for a cozy companion. For a more celebratory touch, a light sparkling cider or a sweet dessert wine would complement the pumpkin flavors beautifully. My mom always pairs it with hot cocoa in winter, and it’s a nostalgic treat!
How to Store Pumpkin Mousse Pie
After all the love and effort put into creating this wonderful Pumpkin Mousse Pie, you’ll want to make sure any leftovers stay as fresh and delicious as possible! Proper storage is key to preserving that perfect texture and flavor.
Fridge Storage
Your pie will keep beautifully in the refrigerator for up to 3-4 days. I always recommend covering it loosely with plastic wrap or placing it in an airtight pie carrier to prevent it from absorbing any other fridge odors and to keep the crust from becoming soggy. This also helps maintain the creamy texture of the mousse.
Freezer Tips
If you want to enjoy a slice of this delightful pie later, you can freeze it! Wrap the entire pie (or individual slices) tightly in plastic wrap, then an additional layer of aluminum foil. It will stay fresh in the freezer for up to 1 month. When you’re ready to enjoy, simply thaw it overnight in the refrigerator.
Serving After Storage
For the best experience, let your Pumpkin Mousse Pie sit at room temperature for about 10-15 minutes before serving after being refrigerated. This allows the mousse to soften just slightly, enhancing its creamy texture.
Nutritional Benefits
While we often think of desserts as pure indulgence, this Pumpkin Mousse Pie actually offers some lovely benefits! With a base of real pumpkin puree, you’re getting a dose of Vitamin A and fiber. The cream cheese adds a touch of protein and calcium, proving that a treat can be both satisfying and nourishing when made with simple, wholesome ingredients.
