I enjoy making this recipe at the beginning of pumpkin season since I know that it won’t heat up my kitchen, which is a significant plus for those of us living in warmer climates.

But it’s also a great option when you have to create a holiday dessert, and the oven is busy with all the other menu items.

What makes this pumpkin mousse so great is that it’s ridiculously easy to make and can be made in advance, meaning you will have a gourmet dessert ready whenever you want one.

Made in 15 minutes or less, this easy keto dessert has only 4.1 net carbs for a one-cup serving!

This pumpkin mousse dessert uses only a handful of ingredients, making it a great option when you need to silence your sweet tooth!

  • Full-fat cream cheese: Use only blocks of real cream cheese, NOT cream cheese spread, and make sure it’s at room temperature. You can also substitute the cream cheese with mascarpone cheese
  • Sour cream: Full-fat provides the most flavor, plus it’s lower in carbs.
  • Unsweetened pumpkin puree: It’s key that you choose pumpkin puree and not pumpkin pie filling, which is loaded with sugar.
  • Heavy whipping cream is used to keep the cheesecake filling light. You’ll be whipping it with cream cheese. The heavy cream needs to be cold so that it whips up properly.
  • Sugar-substitute: A must in order to keep it low in carbs.
  • Vanilla extract: It heightens the flavor of the mousse.
  • Pumpkin spices: cinnamon powder, ginger powder, nutmeg powder, clove powder, or your favorite pumpkin pie spice.

There are only a few easy-to-follow steps to make this delicious keto-friendly pumpkin dessert. If you can measure and mix, you can enjoy a fluffy keto pumpkin mousse!

  • In a large bowl, using an electric mixer, beat the softened cream cheese, pumpkin puree, keto-friendly sweetener, and spices until creamy and smooth. Set aside.
  • In another medium-sized bowl, beat the cold, heavy whipping cream with an electric mixer just until stiff peaks form.
  • Then, using a spatula, gently fold the whipped cream into the pumpkin mixture.
  • Serve the pumpkin mousse in small serving bowls or cups. 

Which Sugar Substitutes Work Best For Sugar-Free Pumpkin Mousse

When it comes to choosing which sugar substitute to use for this low-carb pumpkin mousse recipe, I have several options you can choose from. \

My first recommendation is Lakanto Monk Fruit because the texture is spot on, and there is barely any aftertaste. It is a monk fruit and erythritol blend.

I can’t keep enough of this stuff stocked in my pantry because it really behaves the most like sugar in my book.  It gets its sweetness from antioxidants called mogrosides, instead of fructose or sucrose.

This is why it’s a great all-natural sugar substitute. Plus, it has zero calories and zero glycemic index.  With that being said, I’m also partial to Swerve an erythritol blend.

Unlike other natural sweeteners like stevia, it has no bitter aftertaste and measures like sugar. Swerve is made from ingredients found in select fruits and starchy root vegetables and contains no artificial ingredients, preservatives, or flavors.

It also has a 0 % impact on blood sugar. You could also use the stevia and erythritol-based brand Pyure for this no-bake cheesecake if you’re a fan of stevia.

This is the only stevia brand that I would even consider because I find all others have an intense aftertaste that I can’t get past. 

But if using Pyure, you will want to use half the amount called for because it’s a much sweeter option. You can also use Splenda with great success if you have trouble sourcing a more natural alternative.
