Pumpkin Mousse Pie Recipe

This pumpkin mousse pie gives you all the cozy flavor of classic pumpkin pie without ever turning on the oven.

The filling is light, fluffy, and gently spiced, and it sits in a buttery graham cracker crust that holds its shape from the first slice to the last.

I first made it for a busy holiday when my oven was already full of turkey and side dishes.

Since then, it has become the pie people ask me to bring to every fall gathering.

It sits right alongside my pumpkin lush, another no-bake pumpkin favorite that disappears fast at potlucks.

The best part is that you can make it a day ahead, so dessert is done before guests arrive.

Why You’ll Love This Pumpkin Mousse Pie Recipe

This pie is proof that a holiday dessert does not have to be complicated.

It comes together with a handful of simple ingredients and a little patience while it chills.

• No oven required: The crust is pressed and chilled, and the filling sets in the fridge, so your oven stays free for the main meal.
• Light and fluffy texture: Folding whipped topping into the pumpkin and cream cheese base creates a mousse that feels airy instead of dense.
• Classic fall flavor: Pumpkin, brown sugar, vanilla, and warm pumpkin pie spice taste like everything you love about the season.
• Make-ahead friendly: It is actually better after a full night in the fridge, which makes holiday planning much easier.
• Beginner approved: There is no custard to temper, no water bath, and no risk of a cracked top.
• Crowd pleaser: Kids and adults both go back for a second slice, especially with a big swirl of fresh whipped cream on top.

Ingredients

Everything here is easy to find at any grocery store, and the list breaks into three simple parts: the crust, the mousse filling, and the fresh whipped cream topping.

If you like to make your crust from scratch in other desserts, my homemade graham cracker crust shares the same basic method with a few extra tips.

• 1 1/2 cups graham cracker crumbs (about 10 full sheets), for the crust
• 6 tablespoons unsalted butter, melted, for the crust
• 1/4 cup granulated sugar, for the crust
• 8 ounces cream cheese, softened to room temperature, for the filling
• 1/2 cup packed light brown sugar, for the filling
• 1 can (15 ounces) pumpkin puree, not pumpkin pie filling, for the filling
• 1 teaspoon pure vanilla extract, for the filling
• 1 1/2 teaspoons pumpkin pie spice, for the filling
• 1/4 teaspoon fine salt, for the filling
• 1 tub (8 ounces) frozen whipped topping, thawed, folded into the filling
• 1 cup cold heavy whipping cream, for the topping
• 2 tablespoons powdered sugar, for the topping
• 1/4 teaspoon ground cinnamon, for dusting the top

Kitchen Equipment Needed

You do not need fancy gear for this pie, but a few good tools make the filling smoother and the slices cleaner.

• A 9-inch glass pie dish
• A food processor for crushing the crumbs (or a zip-top bag and rolling pin)
• An electric hand mixer for beating the cream cheese
• A stand mixer if you prefer a hands-free option
• A silicone spatula for folding and spreading
• A piping bag and star tip set for the whipped cream topping (optional)
• Large mixing bowls, measuring cups, and measuring spoons
• Plastic wrap for covering the pie while it chills

Recommended Products for This Recipe

These are my personal recommendations based on making this pie again and again in my own kitchen.

If you enjoy creamy fall desserts, my pumpkin spice latte tiramisu gets better with the same tools.

1. Pyrex Easy Grab Glass Pie Plate

A glass pie plate lets you see the crust, so you know it is pressed evenly along the bottom and sides.

The deep sides also hold plenty of mousse without spilling, and cleanup is quick.

2. KitchenAid Artisan Series Stand Mixer

Cream cheese needs to be beaten until completely smooth, and a stand mixer does that without tiring your arm.

It leaves the filling silky, with no small lumps hiding in the mousse.

3. Libby’s 100% Pure Pumpkin Puree

This is the can I reach for every fall because the texture is thick and consistent.

That thickness matters here, since it helps the mousse set up firm enough to slice neatly.

4. Wilton Decorating Tips and Piping Bag Set

A large star tip turns plain whipped cream into a bakery-style border in about two minutes.

It is a small upgrade that makes a homemade pie look like a showpiece on the holiday table.

Step-by-Step Instructions: How to Make Pumpkin Mousse Pie

Read through the steps once before you begin, and set your cream cheese out early so it can soften.

1. Get Everything Ready

• Take the cream cheese out of the fridge and let it sit on the counter for about 45 minutes until it is very soft.
• Move the tub of whipped topping from the freezer to the refrigerator so it can thaw slowly.
• Measure out all of your ingredients so you can move smoothly from one step to the next.
• Set out a 9-inch pie dish, a large mixing bowl, and a spatula.

2. Make the Graham Cracker Crust

• Crush the graham crackers in a food processor until they look like fine sand, or seal them in a zip-top bag and crush with a rolling pin.
• Measure 1 1/2 cups of crumbs into a medium bowl and stir in the 1/4 cup granulated sugar.
• Pour in the 6 tablespoons of melted butter and stir with a fork until every crumb looks damp.
• Squeeze a small handful of the mixture. If it holds together, the texture is right.

3. Press and Chill the Crust

• Pour the crumb mixture into the pie dish and spread it out evenly.
• Press the crumbs firmly into the bottom of the dish using the flat bottom of a measuring cup.
• Press the crumbs up the sides of the dish, going as high as the rim for a tall, sturdy edge.
• Place the crust in the freezer for 15 minutes while you make the filling, which helps the butter firm up.

4. Beat the Cream Cheese and Brown Sugar

• Add the softened cream cheese to a large mixing bowl.
• Beat on medium speed for about 1 minute until the cream cheese is completely smooth with no lumps.
• Add the 1/2 cup of packed brown sugar and beat for another minute until creamy and lightened in color.
• Stop and scrape down the sides and bottom of the bowl with a spatula so nothing stays hidden.

5. Mix in the Pumpkin, Vanilla, Spice, and Salt

• Add the entire 15-ounce can of pumpkin puree to the bowl.
• Add the 1 teaspoon of vanilla extract, the 1 1/2 teaspoons of pumpkin pie spice, and the 1/4 teaspoon of salt.
• Beat on low speed until the mixture is smooth, uniform in color, and free of streaks.
• Scrape the bowl once more and mix for a few extra seconds. Taste a tiny bit and add a pinch more spice if you like a bolder flavor.

6. Fold in the Whipped Topping

• Add the thawed whipped topping on top of the pumpkin mixture.
• Switch to a silicone spatula and gently fold from the bottom of the bowl up and over the top.
• Turn the bowl as you fold and keep going until no white streaks remain.
• Stay gentle and avoid stirring hard, since folding keeps all those air bubbles that make the filling light and mousse-like.

7. Fill the Crust and Chill

• Take the chilled crust out of the freezer.
• Spoon the pumpkin mousse into the crust and spread it into an even layer with the back of the spatula.
• Gently tap the pie dish on the counter once or twice to release any large air pockets.
• Cover loosely with plastic wrap and refrigerate for at least 6 hours, or overnight, until the filling is set and sliceable.

8. Whip the Cream Topping

• Just before serving, pour the 1 cup of cold heavy whipping cream into a chilled mixing bowl.
• Add the 2 tablespoons of powdered sugar.
• Beat on medium-high speed for 2 to 3 minutes until stiff peaks form and the cream holds its shape when you lift the beaters.
• Stop as soon as you reach stiff peaks so the cream does not turn grainy.

9. Top, Garnish, and Slice

• Remove the plastic wrap from the chilled pie.
• Spread the whipped cream over the top, or pipe it into swirls or rosettes using a piping bag with a star tip.
• Dust the top lightly with the 1/4 teaspoon of ground cinnamon.
• Slice with a sharp knife dipped in hot water and wiped dry between cuts for clean, neat slices.

Tips for The Best Pumpkin Mousse Pie

A few small habits separate a good pie from a great one.

Many of them also show up in my pumpkin pie cheesecake, especially the one about starting with room temperature dairy.

• Soften the cream cheese completely: Cold cream cheese leaves tiny lumps that will not beat out later.
• Use pumpkin puree, not pie filling: Pie filling is pre-sweetened and spiced, which throws off the balance and the texture.
• Blot the pumpkin if it looks wet: Press the puree between a few paper towels to remove extra moisture for a firmer set.
• Fold, do not stir: Gentle folding protects the airy texture that makes this a mousse.
• Do not rush the chill: Six hours is the minimum, and overnight gives the cleanest slices.
• Chill the bowl and beaters for the cream: Cold tools help the whipped cream reach stiff peaks faster.
• Top right before serving: Fresh whipped cream looks best and will not weep on the surface.

Serving Suggestions

This pie is rich but light, so it works well as the final course after a big holiday dinner.

Serve each slice chilled, straight from the fridge.

• Add an extra dollop of whipped cream and a sprinkle of cinnamon on each slice.
• Drizzle warm caramel sauce over the top for a sweet, salty contrast.
• Scatter chopped toasted pecans or crushed gingersnaps over the cream for crunch.
• Pair a slice with hot coffee, chai tea, or a mug of apple cider.
• Set it on a dessert table next to other fall treats for a beautiful spread.

Variations of Pumpkin Mousse Pie

Once you have the base down, this pie is easy to customize with different crusts and toppings.

If you love the mousse style, try my chocolate mousse pie next.

• Gingersnap crust: Swap the graham crackers for gingersnap cookies for a spicier, crunchier base.
• Biscoff crust: Use Biscoff cookies for a caramelized cinnamon flavor.
• Mousse cups: Skip the crust and spoon the filling into small glasses, then chill for at least 2 hours.
• Chocolate drizzle: Finish the whipped cream with a light drizzle of melted chocolate.
• Maple twist: Replace half of the brown sugar with pure maple syrup for a deeper flavor.
• Store-bought crust shortcut: Use a ready-made graham cracker crust when you are short on time.

Storage and Reheating

This pie is served cold, so there is no reheating needed. It keeps beautifully in the fridge and can even be frozen for later.

• Refrigerator: Cover the pie tightly and store for up to 3 days.
• Freezer: Freeze the pie without the whipped cream topping, wrapped well, for up to 1 month.
• Thawing: Move the frozen pie to the fridge overnight before serving.
• Serving after storage: Add fresh whipped cream and cinnamon just before slicing.
• Individual slices: Store leftover slices in an airtight container so they do not pick up fridge odors.

FAQs About Pumpkin Mousse Pie

1. Can I use pumpkin pie filling instead of pumpkin puree?

I do not recommend it, because pumpkin pie filling already contains sugar and spices.

Using it would make the mousse overly sweet and could change how well the filling sets.

2. How far ahead can I make pumpkin mousse pie?

You can make the pie up to 2 days ahead, and it actually slices best after a full night in the fridge.

Wait to add the whipped cream topping until just before serving so it looks fresh.

3. Why is my pumpkin mousse pie runny?

Runny filling usually comes from too little chill time, wet pumpkin puree, or overmixing the whipped topping.

Blot the pumpkin if needed, fold gently, and give the pie at least 6 hours to set.

4. Can I use homemade whipped cream in the filling?

Yes, whip about 1 1/2 cups of cold heavy cream with a spoonful of powdered sugar to stiff peaks and fold it in.

Homemade cream tastes richer, but the frozen whipped topping holds its structure a little better for a firmer slice.

5. What can I make with leftover pumpkin puree?

Leftover puree is great in baked treats like my pumpkin pie twists.

You can also stir it into oatmeal, pancake batter, or smoothies, or freeze it in small portions for later.

Conclusion

This pumpkin mousse pie is the kind of dessert that makes fall feel a little easier and a lot more delicious.

It is creamy, light, and full of warm spice, and nobody will guess how simple it was to make.

I hope you give this pumpkin mousse pie a try at your next holiday gathering or cozy weeknight.
