The gingersnap crumbs start out looking loose, but a firm press turns them into a tidy little base that holds together once the cups are chilled. I like that this no-bake dessert gives you the familiar pumpkin-and-spice flavors of Thanksgiving without needing oven space. These pumpkin mousse cups have a buttery cookie layer under a soft, airy pumpkin filling, and each portion is already ready to serve.

The texture comes from treating the cream cheese mixture and whipped cream as two separate parts before bringing them together. Smooth the cream cheese first, then whip the cold cream on its own and fold it in gently. That keeps the pumpkin base creamy without knocking all the air out of the whipped cream. After a few hours in the refrigerator, the layers are cool, set, and easy to spoon into.

Kitchen Note

Beat the heavy cream until the peaks stand up before you fold it into the pumpkin mixture. I add it in two batches and stop as soon as the white streaks disappear; folding past that point can flatten the airy texture.

Why the Gingersnap Base Needs a Firm Press, Not an Oven

A no-bake crumb layer has no baking time to bind it. The melted butter coats the gingersnap crumbs, and pressing them into an even layer helps the mixture hold together as the cups chill. If you only scatter the crumbs loosely into the cups, they’ll stay sandy and can mix into the first spoonful of mousse.

Use the back of a small spoon to press the crumbs down across the bottom of each 6-ounce dessert cup. You’re looking for a compact, level layer, not a thick crust climbing the sides. The butter doesn’t need to be cooked or browned; it just needs to be melted and stirred through until the crumbs are evenly moistened. The refrigerator does the setting while the pumpkin mousse chills, so there’s no separate crust-baking step to manage.

That even base also gives the cups a clean contrast: spiced crumbs below, pale-orange mousse above. Keep the crumb layer modest and level so there’s room for the full portion of mousse in each cup.

What the Pumpkin, Cream Cheese, and Whipped Cream Each Bring

Gingersnap crumbs and butter — Gingersnaps bring the warm spice that makes the base taste right alongside pumpkin. Prepared crumbs work well; they don’t need to be an expensive brand. For a milder base, use the same amount of graham cracker crumbs with the melted butter, knowing you’ll lose the gingersnap spice. Press whichever crumb mixture into a compact, even layer.
Cream cheese — It gives the mousse body and a gentle tang, balancing the pumpkin and powdered sugar. Let it soften before mixing; cream cheese straight from the refrigerator is more likely to leave small lumps. Standard cream cheese is fine here, and I don’t recommend replacing it with a thinner soft cheese because the mousse would lose structure.
Pumpkin puree — Choose plain pumpkin puree, not pumpkin pie filling, which is already sweetened and spiced. The puree should blend smoothly into the cream cheese. There’s no need to buy a premium brand; what matters is reaching for puree rather than pie filling.
Cold heavy cream — Heavy cream whips into the airy part of the mousse, while half-and-half doesn’t have the same whipping ability. Keep the cream cold until you’re ready to beat it. The cold temperature helps it whip into firm peaks instead of remaining loose.
Powdered sugar, vanilla, and the spices — Powdered sugar blends into the cream cheese mixture without the graininess granulated sugar can leave behind. Cinnamon, ginger, and nutmeg give the pumpkin its warm, rounded flavor; use spices that still smell fragrant when you open the jar. The vanilla supports those flavors without overpowering them.

Building the Cups Without Losing the Air in the Mousse

Press in an Even Gingersnap Layer

Stir the gingersnap crumbs and melted butter together until the crumbs look evenly moistened, with no dry patches at the bottom of the bowl. Divide the mixture among six 6-ounce dessert cups. Press it into an even layer with the back of a spoon, taking a moment to level the edges so the mousse sits neatly on top.

Beat the Pumpkin Base Until Smooth

Beat the softened cream cheese in a large bowl with an electric mixer for about 1 minute, scraping down the bowl as needed. It should look smooth before the pumpkin goes in. Add the pumpkin puree, powdered sugar, vanilla, cinnamon, ginger, and nutmeg, then beat until the mixture is smooth and combined. If you see cream cheese flecks now, keep mixing and scrape the sides before moving on.

Whip the Cold Cream to Stiff Peaks

In a separate bowl, beat the cold heavy cream for about 2 to 3 minutes, stopping when it reaches stiff peaks. Lift the beaters: the peak should stand upright rather than drooping back into the bowl. Cream that’s only softly whipped won’t give the mousse as much structure, so watch its texture near the end instead of relying only on the timer.

Fold, Fill, and Chill

Fold the whipped cream into the pumpkin mixture in two additions, using a gentle motion until no white streaks remain. A few broad folds are better than vigorous stirring, which knocks air out of the cream. Spoon or pipe the mousse over the crumb layers, cover the cups, and refrigerate them for at least 3 hours, until chilled and set. The filled cups should feel cold and the mousse should hold its shape when scooped.

Two Ways to Adapt These Pumpkin Mousse Cups

Make the Gingersnap Base Gluten-Free

Replace the gingersnap crumbs with the same amount of gluten-free gingersnap crumbs, then stir them with the melted butter and press as usual. This keeps the spiced-cookie character; the exact flavor and crunch depend on the cookies you choose. The mousse ingredients themselves remain unchanged.

Make a Layered Parfait-Style Cup

For a more layered look, divide the crumb mixture so you can press some into the bottoms and scatter the rest between spoonfuls of mousse. Keep the same total crumb mixture and butter; the added crumb layer gives you more cookie texture in each bite but makes the cups look less like a clean two-layer dessert.

Make-Ahead, Storage, and Serving

Refrigerator: Keep the cups covered and refrigerated for up to 3 days. The crumb layer gradually softens as it sits, though the mousse stays spoonable.
Freezer: Freezing isn’t a good fit for this airy dairy mousse; thawing can leave it watery and less smooth.
Serving: Serve the cups cold after they’ve chilled and set. There’s no reheating step for this dessert.

Questions That Come Up While Making Pumpkin Mousse Cups

Can I use pumpkin pie filling instead of pumpkin puree?+

No. Pie filling is already sweetened and spiced, so it would change the balance of the mousse. Use plain pumpkin puree for the smooth pumpkin flavor and the measured spices in this version.

Why did my pumpkin mousse turn out loose?+

The most common cause is cream that didn’t reach stiff peaks before folding. If the cups are already filled, give them the full chill and check again; the mousse needs time to become cold and set. For the next batch, look for peaks that hold upright when you lift the beaters.

How do I fix small lumps in the pumpkin mixture?+

If the cream cheese mixture is still in the bowl, scrape down the sides and beat it until smooth before folding in the whipped cream. Once the whipped cream is folded in, more beating can deflate the mousse, so it’s better to get the cream cheese smooth at the earlier stage.

Can I pipe the pumpkin mousse into the cups?+

Yes. Transfer the finished mousse to a piping bag and pipe it over the crumb layer, or spoon it in for a more casual finish. Either way, keep the crumb layer in place and cover the cups before chilling.

Can I make six smaller portions instead of using 6-ounce cups?+

You can divide the same mixture among smaller cups for smaller servings. The cups will be less full, and the recipe will make more than six portions if you divide it into more than six containers.
