How To Make Pumpkin Mousse Pie Step by Step

1. Crush Cookies and Press Crust

In a food processor, pulse 1 (8.8 ounce or 250 gram) package Biscoff / Speculoos cookies into fine crumbs, mix with 7 tablespoons (99 grams) unsalted butter, melted, firmly press mixture into the bottom and sides of a 9-inch pie dish, and chill in the refrigerator for 20 minutes to set.

2. Whip Cold Heavy Cream

In a chilled mixing bowl, whip 1 cup (237 grams) heavy whipping cream, cold on medium-high speed until stiff peaks form, then transfer to a separate bowl and set aside in the refrigerator.

3. Beat Pumpkin Cream Cheese Base

In the same mixing bowl, beat 4 ounces (113 grams) cream cheese, at room temperature, 1/4 cup (50 grams) light brown sugar, 1/2 cup (122 grams) canned pure pumpkin puree, 1 teaspoon vanilla extract, 1/2 teaspoon ground cinnamon, 1/8 teaspoon ground cloves, 1/8 teaspoon ground nutmeg, and 1/8 teaspoon ground ginger until completely smooth and lump-free.

4. Fold Mousse and Fill Crust

Gently fold the whipped heavy cream into the spiced pumpkin cream cheese mixture using a rubber spatula just until combined, then spread the mousse evenly into the chilled cookie crust.

5. Whip Cinnamon Vanilla Topping

In a clean bowl, whip 1 cup (237 grams) heavy cream, cold, 3 tablespoons (23 grams) powdered sugar, sifted, 1 teaspoon vanilla extract, and 1 teaspoon ground cinnamon on medium-high speed until billowy, medium-stiff peaks form.

6. Top, Chill, and Serve

Spoon or pipe the cinnamon whipped cream over the pumpkin mousse layer, chill in the refrigerator for at least 4 to 6 hours (or overnight) until set, and slice into clean wedges.

Tips For The Best Pumpkin Mousse Pie

• Use Pure Pumpkin Puree: Make sure you use 100% pure canned pumpkin puree rather than pre-spiced pumpkin pie filling, which has added water and excess sugars.
• Bring Cream Cheese to Room Temp: Ensure your brick cream cheese is completely soft before beating so it blends smoothly without creating small white lumps.
• Keep Whipping Cream Ice-Cold: Chill your bowl, beaters, and heavy cream thoroughly before whipping to achieve maximum airy volume and stable peaks.
• Fold Gently with a Spatula: Use slow, sweeping motions when folding whipped cream into the pumpkin base to preserve the fluffy, aerated mousse texture.
• Allow Ample Chilling Time: Refrigerate the assembled pie for at least 4 to 6 hours so the dairy fats firm up for sharp, bakery-clean slices.

Storage Instructions

• Fridge: Keep leftover pie stored inside an airtight pie keeper or loosely covered with plastic wrap in the refrigerator for up to 4 days.
• Freezer: Freeze the assembled pie without the whipped cream topping tightly wrapped in plastic wrap and aluminum foil for up to 2 months; thaw in the fridge before topping.
• Reheat: This pie is a chilled dessert and should never be heated; serve cold directly from the refrigerator for the best mousse texture.

Serving and Pairing Ideas

• Serve chilled pie slices garnished with extra crushed Biscoff cookie crumbs, white chocolate curls, or a drizzle of caramel syrup.
• Pair your sweet holiday treat with a hot mug of decaf black coffee, a warm espresso, or herbal chamomile tea.
• Serve alongside a cold glass of whole dairy milk, creamy oat milk, or a warm mug of spiced apple cider.

Frequently Asked Questions

What makes Biscoff cookies ideal for this pie crust?

Biscoff (Speculoos) cookies are packed with rich caramelized brown sugar and warming Belgian spices. Their crisp crunch and deep caramel notes complement the pumpkin mousse and warm spices much better than plain graham crackers.

Can I make this no-bake pie a day in advance?

Yes, absolutely! This pie is one of the best make-ahead desserts for the holidays. You can prepare and assemble the entire pie 24 hours in advance, keep it chilled in the refrigerator, and serve it fresh for dinner.

Why is my pumpkin mousse runny instead of thick?

A runny filling usually happens if the heavy cream was under-whipped before folding or if the pie was not chilled long enough. Make sure to whip the cream to stiff peaks and give the pie at least 4 to 6 hours to set in the refrigerator.

Can I pipe the cinnamon whipped cream on top?

Yes! The cinnamon whipped cream whips up sturdy enough to hold its shape beautifully when piped through a large star piping tip, creating an elegant bakery border around the edge of the pie.
