Light, airy, and beautifully spiced — this creamy pumpkin chiffon pie tastes like a cloud made of fall. It’s the nostalgic holiday dessert I learned from my grandma, and it never fails to disappear from the table.

The magic of this pie is all in the texture — that silky pumpkin custard folded with fluffy egg whites feels almost cloud-like, yet still rich with warm fall spices. The Biscoff crust adds a buttery caramel crunch, the filling chills into a soft, airy set, and every bite tastes like the lighter, dreamier cousin of classic pumpkin pie. It’s the kind of dessert that somehow disappears faster than anything else on the holiday table.

If you love cozy pumpkin desserts, be sure to check out my Classic Pumpkin Pie and my top-rated Sweet Potato Pie with Condensed Milk. And if you’re in the mood for something a little different, try my No Bake Pumpkin Pie or my chilled, creamy Million Dollar Pie — both are longtime holiday favorites.

This pie feels like home — soft, spiced, and full of old-fashioned charm. 💗

✨ Before You Begin

✨ Use enough butter for the crust. Biscoff cookies are drier than graham crackers, so the crust needs a generous amount of melted butter to hold its shape once chilled.

✨ Gelatin sets the chiffon texture. For a stable, sliceable pie, use the full amount of gelatin so it firms without losing its dreamy lightness.

✨ Cool the custard fully before folding. Adding whipped egg whites to a warm base deflates the fluff and prevents an airy chiffon.

✨ Plan for chill time. This pie needs at least 4 hours in the fridge — overnight is even better for clean, beautiful slices.

✨ Serve chilled. Chiffon is at its best cold, lightly set, and topped with soft pillows of whipped cream.

Pumpkin Chiffon Pie Ingredients + Key Notes

This is just a quick glance at what you’ll need. For exact measurements and the full ingredient list, head down to the recipe card below.

Cookie Crust

Biscoff cookies — They add warm caramelized flavor that pairs beautifully with pumpkin.
Butter — Helps bind the crust and adds richness.
Salt — Just a pinch enhances all the warm cookie flavor.

Pie Filling

Gelatin — Gives the chiffon its structure and allows the pie to slice cleanly.
Egg yolks — Cook into a silky, custardy base.
Sugar — Divided: most goes into the custard; a tablespoon stabilizes the whipped egg whites.
Whole milk — Adds richness and helps the custard thicken.
Pumpkin purée — The star ingredient; make sure it’s 100% pure pumpkin, not pie filling.
Warm spices — Cinnamon, ginger, nutmeg, allspice, and cloves deliver classic pumpkin flavor.
Egg whites — Whipped and folded in for that signature chiffon lightness.
Heavy cream + powdered sugar — Whipped together for a soft, billowy topping.

⭐ Pro Tips

⭐ The egg-white question — here’s how my grandma taught me–My grandma always folded raw whipped egg whites into the cooled pumpkin custard — that’s the classic, old-fashioned chiffon method that gives this pie its iconic light and airy texture. If that’s how you grew up eating it, you’re in very good company.
But if you have concerns — which are totally legitimate, especially for children, pregnant women, elderly guests, or anyone immunocompromised — there’s a safe alternative that keeps the texture just as dreamy: Heat the egg whites and sugar over a double boiler to 160°F, then whip and fold them in. This gives you the same chiffon lift with fully cooked whites.

⭐ Don’t rush the cool-down. If your custard is even slightly warm when folding in the egg whites, they’ll deflate instantly.

⭐ Chill longer for cleaner slices. Four hours is the minimum, but overnight gives you picture-perfect wedges.

⭐ Use real pumpkin purée. Pumpkin pie MIX has spices and sugar — not what you want here.

🥣 How to Make Pumpkin Chiffon Pie

Start by mixing your crushed Biscoff cookies with melted butter and salt, then press the mixture firmly into your pie dish and bake it until fragrant. While it cools, sprinkle gelatin over water so it can bloom. In a saucepan, whisk the bloomed gelatin with the egg yolks, milk, spices, salt, and sugar, cooking until the mixture thickens into a custard. Stir in the pumpkin and let it cool completely.

Next, beat the egg whites to soft peaks, add the tablespoon of sugar, then whip to stiff peaks. Gently fold the whites into the cooled pumpkin custard until airy and evenly combined, then pour it all into your crust. Chill for at least 4 hours (longer is better!), whip your cream with powdered sugar and vanilla, and spread or dollop it generously over the top before serving.

Storing + Freezing + Make-Ahead Tips

Storing

Keep the pie covered in the refrigerator for up to 3 days. Because chiffon is a delicate, airy filling, it should always be stored chilled.

Freezing

You can freeze pumpkin chiffon pie, but it must be frozen before adding the whipped cream topping. Wrap the pie tightly and freeze the filling in the crust on its own. When you’re ready to serve, thaw it overnight in the refrigerator, then whip the cream fresh and spoon it over the chilled pie.

Make-Ahead

This is a fantastic day-ahead dessert. Make the pie, cover, and refrigerate overnight. Whip the cream fresh before serving for the best texture.

✦ Frequently Asked Questions

✦ Are the eggs fully cooked in this pie?

The yolks are cooked when the custard thickens, reaching a safe temperature as they heat. Traditionally, the egg whites remain raw, which is how I was taught by my grandma. If you prefer a fully cooked version, simply warm the whites and sugar over a double boiler to 160°F, then whip. This makes the pie safe for any guest.

✦ What makes a chiffon pie different from a regular pumpkin pie?

A classic pumpkin pie is a baked custard, thickened with eggs in the oven. A chiffon pie is completely different — it’s lighter, airier, and more mousse-like because whipped egg whites are folded into the cooked pumpkin custard. The result is a soft, cloud-like texture that melts in your mouth.

✦ Why isn’t this pie baked like regular pumpkin pie?

Chiffon pie gets its structure from gelatin + whipped egg whites, not from oven baking. This is why the texture is so light and mousse-like.

✦ Do I have to use gelatin?

Yes. Gelatin is essential for giving the chiffon structure so it slices cleanly. Without it, the filling will taste delicious but won’t hold its shape — it will slump when you cut into it.

✦ My filling is runny — what went wrong?

A runny chiffon is almost always a gelatin issue. Either the gelatin didn’t fully bloom, the custard wasn’t cooked long enough to activate it, or the pie didn’t chill for the full amount of time. Chill the pie overnight for the most reliable set.

✦ Why does my chiffon filling deflate?

This usually means the egg whites were either overbeaten or handled a little too firmly when folding. For the best lift, whip the whites only to soft peaks before adding the sugar, then fold gently with a light hand to keep all that airy volume intact.

✦ Can I use graham crackers instead of Biscoff?

Absolutely — just increase the butter to ensure a sturdy crust.

✦ How long does Pumpkin Chiffon Pie need to chill?

At least 4 hours, but overnight is ideal. The longer chill allows the gelatin to fully set and gives you those perfect, clean slices.
