Keto Pumpkin Fluff

Creamy, whipped, and full of cozy fall flavor, this keto pumpkin fluff dip is like pumpkin pie in a cloud. No baking, no crust, just sweet pumpkin spice swirled into a dreamy whipped cream base.

It looks like mousse. It tastes like fluff. And it’s the easiest dessert you’ll make this season.

I first made this after a failed keto pumpkin mousse recipe, and it turned into something even better, lighter, fluffier, and perfect for dipping graham-style keto cookies.

Why You’ll Love This Recipe

• Light, airy, and spoonable
• Perfect for fall, Thanksgiving, or cozy nights in
• No cream cheese, just clean whipped fluff
• Low carb, sugar free, and keto approved

Ingredients

• Heavy whipping cream – makes it thick and creamy
• Unsweetened pumpkin puree – adds rich fall flavor without extra carbs
• Powdered sweetener – like Swerve or monk fruit for zero sugar
• Pumpkin pie spice – your go-to cozy blend
• Vanilla extract – brings it all together
• Cinnamon (optional) – adds warmth and depth

Instructions 

• Add everything to a large mixing bowl: heavy cream, pumpkin puree, sweetener, vanilla, and spices.
• Whip until stiff peaks form: Use a hand mixer or an electric mixer or a stand mixer. You’ll see the pumpkin mixture thicken and fluff up after about 5–7 minutes. It should feel like soft peaks of cloud, stop whipping as soon as it holds shape on the beater. 
• Serve however you like: Pipe it fancy into cups or swirl it into a bowl for dipping.
• Optional: Top with extra cinnamon or chopped pecans for crunch.

Expert Tips

• Room temp ingredients whip faster
• Use pure pumpkin puree (not pie filling!)
• Don’t overwhip or it may turn to butter
• Pipe for presentation or scoop into bowls for casual dipping
• Chill 10–20 minutes before serving for best texture

Ingredient Swaps

• Need dairy free? Swap heavy cream for whipped coconut cream, just chill the can overnight and use only the thick top.
• Swap powdered sweetener with monk fruit, allulose, Stevia or erythritol blends
• Add softened cream cheese to make it thicker, like traditional mousse

Storage Tips

• Store covered in the fridge for up to 3 days
• Freeze up to 1 month, then thaw in the fridge and rewhip lightly if needed

Conclusion

This recipe started life as a mousse, but the ingredients and texture told a different story. It’s light, airy, and made for dipping, not slicing. That’s why it’s now called keto pumpkin fluff.

No crust, no cheese, no stress. Just a cozy, low carb dessert that takes minutes. If you’re new to keto desserts, this one’s basically foolproof, no baking, no measuring stress, and nothing gritty or gummy, just pure whipped fluff.
