Ingredients You’ll Need
The beauty of this Pumpkin Mousse lies in its simplicity. With just a handful of pantry staples, each ingredient plays a crucial role in building its creamy texture, rich flavor, and stunning autumnal color.
- 1 cup canned pumpkin puree: Provides a dense, velvety base packed with natural sweetness and vibrant color.
- 1 cup heavy cream: Whipped into soft peaks to lend lightness and decadence to the mousse.
- 1/2 cup granulated sugar: Balances the earthiness of pumpkin with a touch of sweetness.
- 1 tsp ground cinnamon: Adds warmth and spice typical of cozy fall desserts.
- 1/4 tsp ground nutmeg: Brings subtle nutty undertones that enhance the pumpkin’s flavor.
- 1 tsp pure vanilla extract: Elevates the entire mousse with a sweet, aromatic finish.
- 1 tbsp gelatin powder: Provides the gentle structure so the mousse holds its airy shape.
- 2 tbsp water: Used to bloom the gelatin, making it easy to incorporate smoothly.
How to Make Pumpkin Mousse
Step 1: Bloom and Dissolve the Gelatin
Start by sprinkling gelatin powder over the cold water in a small bowl and let it stand for about 5 minutes. This “blooming” allows the gelatin crystals to absorb water and swell. Then, heat the mixture in short bursts of 10 seconds in the microwave until it dissolves completely, ensuring no lumps remain. This step is essential for a perfectly smooth mousse.
Step 2: Mix the Pumpkin and Spices
In a medium bowl, whisk together pumpkin puree, sugar, cinnamon, nutmeg, and vanilla extract until smooth. This blend forms the flavorful core of your Pumpkin Mousse, infusing it with those irresistible fall spices.
Step 3: Combine Gelatin with Pumpkin Mixture
Pour the warm gelatin mixture into the pumpkin mix and stir well. The gelatin is what will help the mousse set into that delicate, soft texture without being too firm.
Step 4: Whip the Cream
In a separate bowl, whip the heavy cream until soft peaks form—the cream should be fluffy but still hold its shape. This is key to giving the dessert its light, airy feel.
Step 5: Fold the Cream into the Pumpkin Mixture
Gently fold half of the whipped cream into the pumpkin mixture to lighten it up, then carefully fold in the rest until the mixture is uniform and streak-free. Be gentle here to keep as much air in the mousse as possible.
Step 6: Chill and Set
Transfer the mousse into serving dishes or ramekins, cover, and refrigerate for at least 2 hours. This waiting game allows the mousse to set beautifully and develop its full flavor.
How to Serve Pumpkin Mousse

Garnishes
A simple dusting of cinnamon or a sprinkle of crushed gingersnap cookies adds a lovely crunch and complementary flavor. For a fresh twist, try topping with a dollop of whipped cream and a few toasted pecans or chopped candied ginger. These garnishes not only amp up the visual appeal but also add texture and flavor contrast.
Side Dishes
Serve this Pumpkin Mousse alongside spiced apple compote or a crisp winter salad for a balance of sweet and tart flavors. It also pairs beautifully with a cup of chai tea or hot apple cider, making your dessert experience cozy and complete.
Creative Ways to Present
Elevate your presentation by serving the Pumpkin Mousse in clear glasses or mason jars layered with crushed gingerbread or graham cracker crumbs. You can also pipe the mousse into bite-sized portions for party hors d’oeuvres or set it in a decorative mold for a statement centerpiece. The possibilities are endless!
Make Ahead and Storage
Storing Leftovers
Leftover Pumpkin Mousse can be covered tightly with plastic wrap and stored in the refrigerator for up to 3 days. Keep it chilled to maintain its texture and freshness—it tastes just as wonderful the next day!
Freezing
While gelatin-based mousses can be frozen, it’s best to avoid freezing Pumpkin Mousse as it may alter the delicate texture and cause it to separate upon thawing. For optimum quality, enjoy it fresh or refrigerated instead.
Reheating
Since this dessert is best served cold, reheating is not recommended. Simply remove it from the fridge about 10 minutes before serving to take the chill off slightly without losing its creamy consistency.
FAQs
Can I use fresh pumpkin instead of canned for Pumpkin Mousse?
Absolutely! Just make sure to roast and puree the pumpkin well, then drain any excess moisture for the best consistency and flavor in your mousse.
Is gelatin necessary for this Pumpkin Mousse recipe?
Gelatin helps the mousse set into a light, airy shape without being too dense. Without it, you may end up with a looser, more pudding-like texture.
Can I make this dessert vegan?
To make a vegan Pumpkin Mousse, substitute the heavy cream with coconut cream and use agar-agar powder instead of gelatin, following the manufacturer’s instructions for blooming and dissolving.
How long can I refrigerate Pumpkin Mousse before it goes bad?
Refrigerated Pumpkin Mousse stays fresh for about 3 days. Beyond that, the texture and flavor may start to degrade, so it’s best to enjoy it sooner.
Can I add other spices to customize the flavor?
Yes! Pumpkin Mousse is versatile, so feel free to experiment with ground cloves, allspice, or even a pinch of ginger to suit your taste preferences.
