Ingredients to Make Keto Pumpkin Cheesecake Mousse
You only need a handful of ingredients to make this easy keto pumpkin mousse. Each one helps create its creamy texture and delicious pumpkin spice flavor.
Heavy cream: Adds richness and creaminess to the mousse. Use heavy cream suitable for whipping.
Pumpkin puree: Gives the mousse its pumpkin flavor and beautiful autumn color. Choose plain pumpkin puree with no added sugar or spices, rather than pumpkin pie filling.
Cream cheese: The key to the cheesecake-inspired flavor and creamy texture. Let it soften to room temperature before mixing to help prevent lumps.
Low-carb sweetener: Adds sweetness without using regular sugar. Use the sweetener specified in the recipe for the best results.
Pumpkin pie spice: Gives the mousse its classic fall flavor with a warm blend of pumpkin pie spices.
Vanilla extract: Enhances the sweetness and complements the pumpkin and spices.
If you don’t have pumpkin pie spice or can’t find it, substitute the following for the amount I used: cinnamon, ginger, nutmeg, and allspice.

How to make Keto Pumpkin Cheesecake Mousse

Tips for the Best Keto Pumpkin Mousse
Follow these simple tips to make a smooth, creamy, and delicious keto pumpkin mousse every time.
- Use room-temperature cream cheese: Let the cream cheese soften before mixing. This helps create a smooth consistency and prevents lumps.
- Choose the right pumpkin puree: Use plain, unsweetened pumpkin puree, not pumpkin pie filling, which may contain added sugar and spices.
- Use cold heavy cream: Cold cream whips more easily and helps create a light, fluffy texture.
- Mix until smooth: Beat the cream cheese and other ingredients according to the recipe instructions until the mixture is creamy and evenly combined.
- Adjust the sweetness carefully: Different keto sweeteners have different levels of sweetness. Use the type specified in the recipe for the best results.
- Allow time to chill: Refrigerating the mousse before serving helps it set and allows the pumpkin spice flavors to develop.
- Make it look special: Serve the mousse in individual dessert glasses and finish with a light dusting of cinnamon, if desired.
How to Store Keto Pumpkin Mousse
In the refrigerator: Store leftover keto pumpkin mousse in an airtight container or cover the individual serving glasses tightly with plastic wrap. Keep it refrigerated at 40°F (4°C) or below.
How long does it last? For the best quality and food safety, enjoy this mousse within 3–4 days when properly refrigerated. Avoid leaving it at room temperature for more than 2 hours, or 1 hour if the temperature is above 90°F (32°C).
Can you make it ahead of time? Yes! This pumpkin mousse is a convenient make-ahead dessert. Prepare it in advance, cover it, and keep it refrigerated until you are ready to serve.
Can you freeze pumpkin mousse? Freezing is not recommended unless you have tested the results. Cream cheese and whipped cream can change texture after thawing, potentially making the mousse less smooth and creamy.
For the best texture, serve the mousse chilled straight from the refrigerator.
