Ingredients

(Tip: You'll find the full list of ingredients and measurements in the recipe card below.)

• 15 ounces canned 100% pumpkin puree (not pumpkin pie filling)

• ½ cup powdered monk fruit sweetener, divided

• 2 teaspoons pure vanilla extract

• ¾ teaspoon ground cinnamon

• ⅛ teaspoon pumpkin pie spice

• ⅛ teaspoon ground nutmeg

• ¾ cup heavy cream

• Whipped cream, for topping (optional)

• Granola or crushed cookies, for garnish (optional)

Directions

1. Mix Pumpkin Base:
   In a large mixing bowl, whisk together the pumpkin puree and ¼ cup of the sweetener. Add vanilla extract, cinnamon, pumpkin pie spice, and nutmeg. Whisk until smooth and well combined. Set aside.

2. Whip the Cream:
   In a separate bowl, pour in the heavy cream and the remaining ¼ cup sweetener. Using an electric mixer, beat the cream on medium-high speed until soft peaks form.

3. Combine Gently:
   Add the whipped cream to the pumpkin mixture. Using a rubber spatula, gently fold the two mixtures together until fully incorporated. Avoid overmixing to preserve the mousse’s light texture.

4. Chill:
   Spoon the mousse into small dessert bowls or ramekins. Cover and refrigerate for at least 1 hour, or until thoroughly chilled.

5. Serve:
   Just before serving, top with whipped cream and a sprinkle of granola or crushed cookies if desired. Enjoy!

FAQs

Can I use a different sweetener?

Yes, powdered erythritol, allulose, or stevia blends work well. Just make sure it’s powdered so it dissolves smoothly.

Is canned pumpkin keto-friendly?

Yes, in moderation. Pumpkin is lower in carbs compared to many other vegetables and is commonly used in keto recipes.

Can I use whipped topping instead of whipped cream?

If you're not strictly keto, yes—but for a cleaner, low-carb option, stick with freshly whipped heavy cream.

How long can I make this in advance?

You can make it up to 2 days ahead. It keeps well and may even improve in flavor as it chills.

Can I freeze pumpkin mousse?

Yes. Freeze in individual portions and thaw in the fridge. You can even enjoy it semi-frozen for a cool twist.

Can I make this dairy-free?

Yes, swap heavy cream for chilled coconut cream and whip it the same way.

How do I know when the cream is whipped enough?

When soft peaks form—meaning the cream holds its shape but still gently folds over—stop mixing.

Can I add protein powder?

Yes, a scoop of vanilla or unflavored protein powder can be added to the pumpkin base to boost protein content.

What kind of pumpkin should I use?

Use canned 100% pumpkin puree, not pumpkin pie filling, which contains added sugar and spices.

Can I make this into a pie filling?

Absolutely. Pour it into a pre-baked low-carb crust and chill until set for a no-bake mousse pie.
