What Is Pumpkin Fluff Mousse?

Pumpkin fluff mousse is a no-bake dessert that combines whipped topping, pudding mix, and pumpkin puree into a mousse-like texture. It’s flavored with warm fall spices like cinnamon and nutmeg, and it can be served in cups, jars, or even piped into pie shells.

Unlike traditional mousse, this recipe requires no eggs or gelatin — making it faster, safer, and easier for anyone to prepare.


Ingredients: Simple and Fall-Perfect

Here’s everything you’ll need for your new favorite no-bake mousse.

📝 Ingredients List:

Ingredient Amount Why It’s Important
Pumpkin puree 1 cup (100% canned pumpkin) Base of the mousse, rich in flavor and fiber
Instant vanilla pudding mix 1 (3.4 oz) box Adds sweetness and thickens the mixture
Whipped topping (Cool Whip or similar) 8 oz (thawed) Gives the mousse its airy, fluffy texture
Pumpkin pie spice 1 tsp Delivers warm, comforting fall flavor
Ground cinnamon ½ tsp Adds extra spice and depth
Vanilla extract 1 tsp Enhances the overall flavor
Milk (dairy or plant-based) ¼ cup Helps dissolve pudding and smooth the texture
Optional topping: whipped cream, cinnamon, crushed cookies As desired For layering or garnish

Always use 100% pumpkin puree, not pumpkin pie filling.


How to Make Pumpkin Fluff Mousse (Step-by-Step)

Step 1: Mix Pumpkin + Pudding

In a large mixing bowl, whisk together:

  • 1 cup pumpkin puree

  • 1 box vanilla pudding mix (do not prepare first)

  • ¼ cup milk

  • 1 tsp pumpkin pie spice

  • ½ tsp ground cinnamon

  • 1 tsp vanilla extract

Mix until smooth and thick.

Step 2: Fold in Whipped Topping

Using a silicone spatula, gently fold in the thawed whipped topping. This will create a mousse-like texture. Mix until no streaks remain, but don’t over-stir—airiness is key!

Step 3: Chill and Serve

Spoon the mousse into small bowls, cups, or jars. Chill for at least 30 minutes to let the flavors blend and texture firm up.

🧡 Serve with a dollop of whipped cream and sprinkle of cinnamon or crushed cookies for extra flair!

FAQs: Pumpkin Fluff Mousse

Q1: Can I use pumpkin pie filling instead of puree?

No. Pumpkin pie filling contains added sugars and spices that may make the mousse too sweet or off-balance. Always use 100% pumpkin puree.


Q2: Can I make this without pudding mix?

You can, but the pudding mix gives structure and sweetness. If omitting, use softened cream cheese or Greek yogurt and sweeten with maple syrup or powdered sugar—though the texture will be thicker and more cheesecake-like.


Q3: Is this mousse gluten-free?

Yes! As long as your pudding mix and whipped topping are labeled gluten-free, this recipe is naturally free from gluten. Check labels carefully.


Q4: Can I serve this to kids?

Absolutely. It’s kid-friendly, alcohol-free, and contains no eggs or raw ingredients. You can even pack it in small containers for lunchbox treats!


Q5: Can I double or triple the recipe?

Yes! Simply scale up all ingredients proportionally. This mousse is perfect for parties and large holiday gatherings.
