When Fall finally comes along, pumpkin everything is part of the magic! But one of my very favorite pumpkin recipes isn’t a cookie, bread, muffin, or soup – it’s this velvety Low Carb Pumpkin Mousse! With just a handful of ingredients and hardly any prep time at all, you can serve up a truly special dessert that’s fluffy and yet rich, with the delicate and spicy flavor of pumpkin pie!

What Is Mousse

Mousse is a whipped dessert. It’s a cross between chilled pudding and whipped cream – think light, airy, and sweet. You can serve it alone or layer it in a parfait or trifle. This pumpkin mousse is a lovely seasonal alternative to the more common Chocolate Mousse – and one you’ll come back to repeatedly.

Pumpkin Mousse Ingredients

  • Pumpkin Puree: Make sure it’s 100% pumpkin, not pumpkin pie filling.
  • Vanilla: Pure vanilla extract is what I prefer, but you can also use regular vanilla flavoring.
  • Cinnamon, Nutmeg, and Pumpkin Pie Spice
  • Heavy Cream: Avoid half and half and milk in this recipe — you need to be able to whip the cream.
  • Sweetener: I use monk fruit, but you can substitute your preferred powdered sweetener.

How To Make Low Carb Pumpkin Mousse

  1. Combine Ingredients: Mix the pumpkin puree, vanilla, and spices in a large mixing bowl.
  2. Whip the Cream: In a separate bowl or using a stand mixer, whip the cream together with the sweetener until soft peaks form.
  3. Fold: Gently fold the whipped cream into the pumpkin mixture, working slowly and in batches until they are combined.
  4. Chill: Spoon the mousse into serving cups, glasses, or bowls. Chill for an hour before serving.

Recipe Tips

  • Master the Fold: It’s important to fold the whipped cream into the pumpkin mixture rather than stirring or mixing to maintain lightness. Watch here for a quick tutorial.
  • Whipping: Remember that if you keep whipping heavy cream, it will turn from liquid to soft peaks to grainy specks of butter. So whip just until you can pull the beaters from the whipped cream and leave behind soft peaks or hills.
  • Sweeten to Taste: My recipe calls for ¼ cup of monk fruit sweetener, but you can substitute pure maple syrup, stevia, honey, and even cane sugar. Whatever sweetener you use, measure accordingly since not all sweeteners affect a recipe the same way.

  • In a large mixing bowl whisk the pumpkin puree with 1/4 cup sweetener. Add vanilla, cinnamon, pumpkin pie spice, and nutmeg; whisk until well combined. Set aside.
  • In a separate bowl, combine the heavy cream with the remaining sweetener; using an electric mixer beat the mixture until soft peaks form.
  • Add the heavy cream mixture to the pumpkin mixture and, using a rubber spatula, gently fold the mixture until thoroughly incorporated. Fold, don't mix.
  • Divide the mousse evenly among small dessert bowls. Place in the fridge for 1 hour or until chilled.
  • Optionally, top with a dollop of whipped cream and a sprinkle of granola or crushed cookies.
  • Serve.


  • Folding Technique: Gently fold the whipped cream into your pumpkin blend instead of mixing it. This way, you’ll keep that airy texture of mousse.
  • Avoid the Butter Zone: When you’re whipping the heavy cream, don’t overdo it! Take it too far, and you’ll end up with bits that resemble butter. Aim for a texture with soft, creamy peaks.
  • Customize: While I use ¼ cup of sweetener in my recipe, you can switch it up. Whether it’s maple syrup, stevia, honey, or plain cane sugar, remember that each sweetener can alter the dish differently, so adjust your measurements as needed.
