Delicious, creamy keto pumpkin mousse is the perfect fall dessert. I love serving it this time of year because I can make it a day in advance!
This delicate, creamy keto pumpkin mousse is flavored with vanilla and cinnamon. One of its big advantages is that you can make it in advance. In fact, the mousse is way creamier on the second day, probably because the pumpkin and cream have more time to meld.
So if possible, I would suggest making this a day ahead. If you do, whip the cream for the topping on the day you plan to serve the mousse.
The ingredients needed for this recipe
You’ll only need six ingredients to make this tasty dessert (exact measurements are included in the recipe card below):

How to make keto pumpkin mousse
It’s so easy. The detailed instructions are in the recipe card below. Here are the basic steps:
- Start by whisking together the pumpkin, cinnamon and vanilla.
- In a separate bowl, beat the heavy cream with the sweetener.
- Fold the whipped cream into the pumpkin mixture.
- Chill, then top with whipped cream and serve.
Tips for making this recipe a success
- To keep this mousse keto and low carb, I use a low carb granulated sweetener when making it. If you don’t mind sugar, you can use that instead.
- Sometimes, instead of cinnamon, I use pumpkin pie spice. Both versions are excellent, although sticking to cinnamon results in a more delicate, milder flavor.
- You can use a can of pure pumpkin puree in this recipe, or use the same amount (15 oz) of homemade pumpkin puree. Just make sure the homemade pumpkin puree is as smooth and lump-free as commercial pumpkin puree.
Is this keto pumpkin mousse healthy?
I believe it is, for a dessert. Pumpkin, the main ingredient here, is very healthy. Full-fat dairy, according to current research, is harmless for most healthy people, though I would still use heavy cream sparingly.
As for the sweetener, sugar alcohols seem to be fine for most as long as they are consumed in moderation.
More tasty pumpkin desserts
When it comes to pumpkin desserts, we almost always think of pumpkin pie. But there are other, more interesting options.
This delicious keto pumpkin mousse is one of them. I also love pumpkin cheesecake, pumpkin ice cream, and this pumpkin cake is wonderful.
Mousse, in general, is one of my favorite desserts. I love its airy texture. This pumpkin mousse is incredibly light and airy.
What to do with leftover keto pumpkin mousse?
As I said, this dessert actually tastes better the next day. So obviously, if you serve it on the day you make it and have leftovers, go ahead and keep them.
But I don’t think the fluffy texture will last beyond a day or two. I’ve never had a chance to test it, though. We tend to finish this pumpkin mousse pretty fast. 🙂
