This keto pumpkin mousse is light, creamy, and full of cozy pumpkin spice flavor. It has the richness of pumpkin cheesecake, but with a softer, fluffier texture that makes every spoonful feel a little more special.
I love serving it in small glasses for fall gatherings because it looks beautiful without needing much extra effort. It’s especially nice for Thanksgiving when the oven is already busy and you want a dessert you can prepare ahead of time.
Once chilled, the mousse becomes smooth and airy, with plenty of pumpkin flavor and warm spice in every bite.
For all my chocolate lovers, you can also try my keto chocolate mousse. It’s rich, creamy, and perfect when you’re craving something chocolatey.
When pumpkin season comes around, a few of my favorites are keto pumpkin pie, keto pumpkin cheesecake, and keto pumpkin cheesecake bars. This creamy pumpkin mousse is another one I love because it has all those cozy pumpkin spice flavors in a light, fluffy dessert.
Watch this quick video to see how easy it is to make this creamy keto pumpkin mousse.

Keto Pumpkin Mousse Ingredients
Here’s what you’ll need to make this creamy low carb pumpkin mousse.
- Cream cheese – Use full-fat cream cheese at room temperature so it mixes smoothly with the pumpkin.
- Canned pumpkin – Use pure pumpkin purée, not pumpkin pie filling, which already contains added sweeteners and spices. You can also make your own homemade pumpkin puree.
- Heavy cream – Gives the mousse its light, fluffy texture.
- Pumpkin pie spice – Adds the warm cinnamon, ginger, nutmeg, and clove flavors you expect in a pumpkin dessert. You can also use homemade pumpkin pie spice.
- Powdered sweetener – A powdered sweetener blends more smoothly into the cream cheese mixture. You can adjust the sweetness to taste after mixing.
- Vanilla extract – Rounds out the pumpkin and spice flavors.
- Salt – A small pinch helps balance the sweetness.
Optional Whipped Cream Topping
For serving, you can make a simple whipped cream topping with heavy cream, powdered sweetener, and vanilla or rum extract.
How to Make Keto Pumpkin Mousse
The mousse itself comes together in one bowl. The most important part is giving it enough time to chill so the texture can firm up before serving.
- Mix the cream cheese and pumpkin. In a large bowl, use an electric mixer to beat the softened cream cheese, powdered sweetener, and pumpkin purée until smooth and fluffy.
- Add the remaining ingredients. Add the heavy cream, pumpkin pie spice, salt, and vanilla extract. Continue mixing for about 2–3 minutes, or until everything is well combined and fluffy.
- Taste and adjust. Taste the mousse and add more powdered sweetener if desired.
- Chill. Cover and refrigerate for at least 4 hours or overnight.
- Serve. Divide the chilled mousse among four serving cups. Top with whipped cream and a light sprinkle of pumpkin pie spice if desired.
Tip for the Best Texture
Stop mixing once the mousse is smooth and fluffy. Overmixing can cause the mixture to become grainy or begin to separate.
Is This Keto Pumpkin Mousse Dairy-Free?
No. This pumpkin mousse contains both cream cheese and heavy cream, so it is not dairy-free as written.
I haven’t included a tested dairy-free variation in the recipe card, so I don’t recommend a specific 1:1 substitution here.
Is Pumpkin Keto-Friendly?
Yes, pumpkin can fit into a low-carb or keto diet when portion size is taken into account.
In this recipe, the pumpkin is divided among four servings, and the recipe card estimates 6g net carbs per serving.

How to Store Keto Pumpkin Mousse
Cover the mousse and refrigerate it for at least 4 hours or overnight before serving.
When you’re ready to serve, divide it among four glasses and add the whipped cream and pumpkin pie spice just before serving.
