This pumpkin mousse is a creamy, fluffy dessert made with pumpkin puree, sweetened whipped topping, and a hint of warm pumpkin pie spice. It’s a perfect fall treat, featuring a smooth and rich texture with a touch of cinnamon and rum whipped cream for extra flavor. This easy pumpkin mousse is ideal for Thanksgiving, holiday parties, or any time you want a delicious, festive dessert. The mousse sets perfectly in the fridge, and the whipped cream adds a light, flavorful finish.

Ingredients:
For the Pumpkin Mousse:
- 1/2 oz unflavored gelatin (2 packets or 14 grams)
- 1 cup milk (any kind)
- 1 cup granulated sugar
- 15 oz can pumpkin puree
- 1 tsp pumpkin pie spice
- 16 oz sour cream
- 16 oz whipped topping (thawed in the refrigerator)
- 1/2 tsp ground cinnamon (for garnish)
For the Rum Whipped Cream:
- 1 cup heavy whipping cream
- 2 tbsp powdered sugar
- 1 tsp dark or golden rum (or vanilla extract)
Instructions:
- Prepare the Gelatin Mixture: In a small saucepan, combine the gelatin and milk. Heat over medium heat, whisking constantly until the mixture begins to steam and the gelatin dissolves (do not allow it to boil). Remove from heat and allow it to cool for 15 minutes.
- Make the Pumpkin Mousse: In the bowl of a stand mixer, combine the sugar, sour cream, pumpkin puree, and pumpkin pie spice. Mix on medium speed until fully blended. Add the whipped topping and mix on medium-low speed until well combined. Scrape down the sides of the bowl as needed.
- Incorporate the Gelatin: With the mixer running, slowly drizzle in the cooled gelatin mixture. Once fully incorporated, immediately divide the mousse between individual serving cups. Refrigerate for at least 4 hours, or overnight, to allow the mousse to set.
- Make the Rum Whipped Cream: In a separate bowl, use an electric mixer to beat the heavy cream and powdered sugar on high speed for about 2 minutes or until thick and whipped. Add the rum (or vanilla extract) and mix just until incorporated—do not over-beat.
- Serve: Just before serving, pipe or dollop the rum whipped cream on top of the mousse and sprinkle with ground cinnamon for garnish.
Why You’ll Love This Recipe
This pumpkin mousse combines the warm, cozy flavors of pumpkin and spices with a light and creamy texture. The mousse itself is rich but airy, making it the perfect dessert for fall or any occasion that calls for a comforting treat. The addition of rum whipped cream gives it a festive touch, while the cinnamon garnish adds a hint of warmth to each bite.

Tips
- Avoid Boiling the Gelatin: Be sure to heat the gelatin mixture only until it starts to steam. Boiling it can compromise the texture of the mousse.
- Chill Overnight: For the best results, allow the mousse to chill for a full 4 hours, or preferably overnight, to ensure it sets properly.
- Whip the Cream Just Right: Don’t over-beat the whipped cream. Once it holds stiff peaks, stop mixing to avoid turning it into butter.
Variations and Substitutions
- Dairy-Free: Substitute the sour cream and whipped topping with dairy-free alternatives like coconut cream or a dairy-free whipped topping.
- Alcohol-Free: If you prefer not to use alcohol, replace the rum in the whipped cream with vanilla extract for a similar depth of flavor.
- Pumpkin Spice: For an extra boost of pumpkin spice flavor, you can add more pumpkin pie spice or a pinch of cinnamon and nutmeg.
FAQs
- Can I make this ahead of time? Yes, this mousse needs time to set, so making it the day before you plan to serve it is ideal.
- How long will it last? Store any leftovers in an airtight container in the fridge for up to 3 days.
- Can I make it without the gelatin? The gelatin is essential for setting the mousse. Omitting it will result in a thinner, pudding-like texture.
Serving
This pumpkin mousse is perfect for holiday gatherings, fall parties, or as a light after-dinner dessert. Serve it in individual cups for a polished presentation or in a large serving bowl for a more casual approach.
Suggestions
- Garnish with More Toppings: Try topping the mousse with chopped candied pecans, toasted pumpkin seeds, or a drizzle of caramel sauce for added texture and flavor.
- Pair with a Hot Drink: This mousse pairs wonderfully with a warm cup of spiced chai, hot chocolate, or coffee for a cozy dessert experience.
