Why This Recipe Saves You Money
I built this recipe with cost in mind from the very first step. Here’s how it keeps cash in your pocket.
First, it uses canned pumpkin puree. Fresh pumpkin can be a hassle and isn’t always cheaper. A can gives you perfect texture every time for just a few cents per serving.
Second, we make our own pumpkin spice blend. Buying a pre-made jar is often more expensive. You likely have the spices in your cupboard already.
Finally, heavy cream and cream cheese are versatile. You can use the leftovers in other budget meals throughout the week, like whipping up a quick keto stir fry. Nothing goes to waste.

Nutrition Information
Always buy plain canned pumpkin puree, not pumpkin pie filling. The pie mix has added sugar and spices, costs more, and gives you less control.
Check the unit price on cream cheese. The store brand blocks are almost always cheaper than name-brand tubs. They work perfectly here.
Buy heavy cream at a warehouse store if you can. It freezes beautifully for months. Just shake it well after thawing.
For sweeteners, a big bag of a granulated keto sweetener like erythritol is a great investment. It lasts for many, many recipes.
The Budget-Friendly Ingredient List
Here’s everything you’ll need. Measure with your heart, but your wallet will thank you.
- 1 (15 oz) can of pure pumpkin puree
- 8 oz block of full-fat cream cheese, softened
- 1 cup heavy whipping cream, divided
- 1/2 cup powdered erythritol or your favorite keto sweetener
- 1 1/2 teaspoons vanilla extract
- 1 1/2 teaspoons homemade pumpkin spice (see mix below!)
- A pinch of salt
Homemade Pumpkin Spice Mix: In a small bowl, mix 1 tsp cinnamon, 1/4 tsp ginger, 1/4 tsp nutmeg, and 1/8 tsp cloves or allspice. This uses pantry staples and tastes fresher.
How to Make It (Step-by-Step)
This comes together in minutes. The hardest part is waiting for it to chill!
- Start by whipping the cream. In a cold bowl, beat 1/2 cup of the heavy whipping cream until it forms stiff peaks. Set this aside for later.
- In a larger bowl, beat the softened cream cheese until it’s completely smooth. This is key for a lump-free mousse.
- Beat in the pumpkin puree, the remaining 1/2 cup of heavy cream, sweetener, vanilla, your homemade pumpkin spice, and that pinch of salt. Mix until it’s smooth and creamy.
- Now, gently fold in the whipped cream you made first. Use a spatula and a light hand to keep the mixture airy.
- Divide the mousse between four glasses or small bowls. I love using simple mason jars for a cute look.
- Chill for at least 2 hours before serving. This lets the flavors really come together. Top with a little extra whipped cream and a sprinkle of cinnamon if you like.
How to Use Up Every Last Bit (No Waste!)
I hate throwing away food. Here’s how to make sure every ingredient in this recipe gets used.
That leftover canned pumpkin puree? You probably won’t have any, but if you do, freeze it in an ice cube tray. Pop the cubes into smoothies or oatmeal.
Use the rest of the cream cheese on keto bagels or in a quick savory dip. The heavy cream can be whipped for berries or stirred into soups.
The homemade pumpkin spice mix will keep for months. Use it in your coffee, on roasted sweet potatoes, or in your morning yogurt.

Common Questions About This Recipe
Here are answers to the questions I get asked the most about this easy dessert.
Can I make this dairy-free?
You can try, but it changes the texture and cost. For the cream cheese, use a thick coconut cream base. For the heavy cream, chill a can of full-fat coconut milk and whip the solid part.
It won’t be as fluffy, but it will still taste great. Just know that dairy-free specialty products can sometimes be more expensive.
How long will the mousse cups keep in the fridge?
They keep beautifully for up to 4 days. Just make sure they’re covered tightly with plastic wrap. The texture might get a bit softer, but the flavor is still amazing.
I don’t recommend freezing this mousse, as the texture can become a bit grainy when thawed.
My sweetener seems grainy. What did I do wrong?
Some granulated keto sweeteners don’t dissolve well in cold mixes. That’s why I recommend using a powdered version for this recipe.
If you only have granulated, give it a quick blitz in a clean coffee grinder or blender to make a powder. This simple trick makes all the difference.
See? Impressive fall recipes don’t require a trip to a specialty store. With a can of pumpkin and a few basics, you’ve created a holiday dessert that feels luxurious.
This mousse is proof that smart cooking beats expensive cooking every single time. It’s about working with what you have and knowing a few key techniques. For another great example of a simple, satisfying keto snack, check out our recipe for easy homemade keto crackers.
