Ingredients You’ll Need
This recipe shines because of its simple yet thoughtfully selected ingredients, each contributing uniquely to the mousse’s vibrant texture, flavor, and color. Whether it’s the gentle jiggle from gelatin or the punch of pumpkin pie spice, every element plays a pivotal role.
- Unflavored gelatin (1/2 oz): Key for giving the mousse its perfect set without heaviness.
- Milk (1 cup): Adds moisture and helps dissolve the gelatin smoothly.
- Granulated sugar (1 cup): Sweetens the mousse just right, balancing pumpkin’s natural earthiness.
- Pumpkin puree (15 oz can): The star ingredient providing rich flavor and beautiful orange color.
- Pumpkin pie spice (1 tsp): A cozy blend of cinnamon, nutmeg, and cloves that elevates every spoonful.
- Sour cream (16 oz): Adds a subtle tang and creamy density for depth.
- Whipped topping (16 oz, thawed): Lightens the mousse, giving it that classic airy texture.
- Ground cinnamon (1/2 tsp): Used as a garnish for a fragrant finishing touch.
- Heavy whipping cream (1 cup): Whipped with sugar and rum to create the spiced cream topping.
- Powdered sugar (2 Tbsp): Sweetens the cream delicately without graininess.
- Rum (1 tsp): Adds warmth and complexity to the spiced cream; vanilla extract can be used as an alternative.
How to Make Pumpkin Mousse with Spiced Cream and Rum Recipe
Step 1: Bloom the Gelatin
Start by sprinkling the unflavored gelatin over the milk in a small saucepan. Let it sit for a few minutes to bloom, allowing the gelatin granules to absorb the liquid fully and bloom into a gel-like texture. This crucial step ensures your mousse will set perfectly without lumps.
Step 2: Dissolve the Gelatin
Gently warm the milk and gelatin mixture over low heat, stirring constantly until completely dissolved. Be careful not to boil, as too much heat can reduce gelatin’s setting power. Once smooth, remove from heat and set aside to cool slightly.
Step 3: Combine Pumpkin and Sugar
In a large mixing bowl, combine the pumpkin puree with granulated sugar and pumpkin pie spice. Stir until the sugar starts to dissolve into the pumpkin, mixing the classic autumnal flavors seamlessly.
Step 4: Add Sour Cream and Gelatin Mixture
Fold the sour cream into the pumpkin mixture for a creamy, tangy base, then slowly add the slightly cooled gelatin mixture. This step creates the luxurious body of your mousse, melding all the flavors into one silky blend.
Step 5: Incorporate the Whipped Topping
Carefully fold in the whipped topping to the pumpkin mixture. This is what gives your dessert the signature light and fluffy texture, balancing the denser components beautifully.
Step 6: Chill Until Set
Transfer the mousse to serving dishes or a large bowl. Refrigerate for at least 4 hours, or until beautifully firm but still creamy. Patience here rewards you with that melt-in-your-mouth sensation that defines this Pumpkin Mousse with Spiced Cream and Rum Recipe.
Step 7: Prepare the Spiced Rum Cream
While the mousse chills, whip the heavy cream with powdered sugar and rum until soft peaks form. This spiced cream is the crowning glory, adding a boozy warmth and silky richness.
Step 8: Garnish and Serve
Top each portion of mousse with a generous swirl of the spiced cream and a light dusting of ground cinnamon. The finishing touches make your dessert as beautiful as it is delicious.
How to Serve Pumpkin Mousse with Spiced Cream and Rum Recipe

Garnishes
A sprinkle of ground cinnamon or freshly grated nutmeg adds inviting aroma and color contrast. For texture, consider toasted pecans or a light drizzle of caramel sauce to complement the mousse’s creaminess perfectly.
Side Dishes
This mousse pairs wonderfully with buttery shortbread cookies or crisp ginger snaps, providing a satisfying crunch alongside the silky mousse. For a richer touch, a small scoop of vanilla ice cream makes every bite feel even more luxurious.
Creative Ways to Present
Serve the mousse in clear glass parfait cups layered with crushed gingersnap crumbs for visual appeal and added texture. For festive occasions, hollowed mini pumpkins or decorative ramekins elevate the presentation, making it a centerpiece-worthy dessert.
Make Ahead and Storage
Storing Leftovers
You can store any uneaten mousse in an airtight container in the refrigerator for up to 3 days. This dessert holds its delicate texture well but is best enjoyed fresh for peak flavor and lightness.
Freezing
Freezing pumpkin mousse isn’t recommended because the airy texture can suffer and become grainy once thawed. Instead, keep it refrigerated and consume within a few days for the best experience.
Reheating
Since mousse is served chilled, reheating isn’t needed. If you prefer it at room temperature, take it out of the fridge about 10 minutes before serving to soften gently without compromising its structure.
FAQs
Can I use fresh pumpkin instead of canned puree?
Fresh pumpkin can be used if cooked and pureed thoroughly until smooth, but canned pumpkin puree is typically more consistent in texture and flavor, making it the preferred choice for this recipe.
What if I don’t have rum; can I use vanilla extract instead?
Yes! Vanilla extract is a delightful substitute that brings warmth without the alcohol. Use the same quantity to keep the spiced cream balanced and flavorful.
Is gelatin necessary in this Pumpkin Mousse with Spiced Cream and Rum Recipe?
Gelatin is essential for the mousse to set properly and maintain its airy yet stable structure. Without it, the mousse would be too loose to hold its shape.
Can I make this dessert vegan?
This particular recipe relies on dairy and gelatin, so it’s not vegan-friendly as is. However, there are plant-based gelatin substitutes and dairy-free creams that could be experimented with for a vegan variation.
How long does this mousse keep its best flavor after making?
For optimal taste and texture, enjoy your pumpkin mousse within 2 to 3 days of preparation, stored in the fridge. After that, the flavor and texture may begin to deteriorate.
Final Thoughts
There’s something truly special about this Pumpkin Mousse with Spiced Cream and Rum Recipe that just feels like autumn celebration in every bite.
