Keto Pumpkin Mousse Ingredients
For the Mousse
- Cream Cheese – Provides a rich, creamy texture; use full-fat for the best consistency.
- Heavy Cream – Adds fluffiness and richness; ensure it’s cold before whipping for best results.
- Powdered Sweetener – Sweetens the mousse without the carbs; opt for erythritol or Swerve to avoid grittiness.
- Pumpkin Puree – Delivers the signature pumpkin flavor; use pure pumpkin puree, not pumpkin pie filling.
- Pumpkin Spice – Enhances flavor with traditional fall spices; substitute with a mix of cinnamon and a touch of ginger if desired.
Optional Toppings

Step‑by‑Step Instructions for Keto Pumpkin Mousse
Step 1: Whip the Cream
Begin by pouring the cold heavy cream into a stand mixer bowl. Beat on medium-high speed for about 3–5 minutes, until stiff peaks form and the cream looks fluffy and voluminous. This will create a light texture for your Keto Pumpkin Mousse. Once whipped, carefully transfer the cream to a separate bowl to keep it airy.
Step 2: Mix the Cream Cheese
In the same stand mixer bowl, combine the full-fat cream cheese and powdered sweetener. Mix on medium speed for about 2-3 minutes until the mixture is light and fluffy, ensuring there are no lumps remaining. Then, add in the pumpkin puree and pumpkin spice, continuing to mix until the dessert base is smooth and well-combined.
Step 3: Combine Mixtures
Gently fold one-third of the whipped cream into the pumpkin mixture with a spatula. This step lightens the mixture, making it easier to incorporate the remaining cream. Once blended, carefully add the rest of the whipped cream, folding it in until fully integrated. The key here is to maintain that lovely airy texture synonymous with Keto Pumpkin Mousse.
Step 4: Serve the Mousse
Using a spoon or piping bag, portion the mousse into small serving bowls or jars, ensuring they’re evenly filled. You can choose to serve immediately for a fresh, creamy treat or refrigerate for at least 30 minutes if you prefer it chilled. This allows the flavors to meld beautifully, enhancing the overall taste experience.

Keto Pumpkin Mousse Recipe FAQs
What type of pumpkin puree should I use?
Absolutely! Always use pure pumpkin puree and not pumpkin pie filling. The pie filling often contains added sugars and spices that can alter the taste and carb content of your Keto Pumpkin Mousse. Look for 100% pure pumpkin in the can, and check the label for no added ingredients.
How should I store leftover Keto Pumpkin Mousse?
For the best results, place any leftover mousse in an airtight container and store it in the refrigerator. It will stay fresh for up to 5 days. If you plan to savor it longer, consider freezing it for up to 2 months—just make sure to use a freezer-safe container to prevent freezer burn.
Can I freeze Keto Pumpkin Mousse, and how?
Certainly! To freeze your mousse, first, portion it out into individual servings in a freezer-safe container. Ensure it’s sealed tightly to avoid air exposure. When you’re ready to enjoy it, remove it from the freezer and thaw it overnight in the fridge. Once thawed, give it a gentle stir to restore its creamy texture before serving.
What should I do if my mousse isn’t as fluffy as I expected?
Very good question! If your mousse turns out less fluffy, it’s often due to either the whipping cream not being cold enough or not whipping it long enough. Ensure your heavy cream is chilled, and whip it on medium-high speed until stiff peaks form—about 3 to 5 minutes. When folding in the whipped cream, do so gently to maintain that lovely airy texture.
Are there any dietary considerations I should keep in mind?
Yes! The Keto Pumpkin Mousse is inherently gluten-free and sugar-free, making it great for those following a ketogenic or low-carb lifestyle. However, if you have any allergies to dairy or nuts (especially if you’re using toppings like nuts), be sure to keep this in mind as you prepare your mousse or choose your toppings. It’s always smart to check ingredient labels if you have specific dietary needs.
