Costco Pumpkin Pie Copycat Recipe: Spiced Filling and Buttery Lattice Crust

This Costco pumpkin pie copycat recipe delivers the same iconic flavor and texture that makes their version legendary—spiced filling with just the right balance of cinnamon, nutmeg, and clove, all wrapped in a buttery lattice crust that’s crisp yet tender.

After years of testing, I’ve cracked the code to replicate that signature taste without the $15 price tag. The secret lies in precise spice measurements and a slow-baked filling that stays silky-smooth.

What sets this recipe apart is the lattice crust, which requires no special equipment—just a simple pie dough folded into an elegant pattern.

The filling uses evaporated milk for richness and a touch of corn syrup to prevent graininess, while the spices are toasted in butter first to deepen their flavor. This isn’t just another pumpkin pie; it’s the one that’ll fool even the most discerning pie lovers.

By the time it emerges from the oven, you’ll have a pie with a golden, crackly crust and a filling that’s velvety yet firm enough to slice cleanly. The aroma alone—warm spices mingling with vanilla and butter—will have everyone gathering around the table.

Serve it with a dollop of whipped cream or a drizzle of caramel for the full Costco experience.

Perfect for holidays, potlucks, or whenever you crave that restaurant-quality dessert without the wait. The best part? This recipe scales easily, so you can make one for a family of four or double it for a crowd. Let’s get baking!

Ingredients for costco pumpkin pie copycat

Sixteen ingredients. One legendary pie. All the Costco magic at home.

The pumpkin puree is where it starts—Libby’s 100% pure is my go-to, but any unsweetened canned pumpkin works. Evaporated milk is non-negotiable here; it adds that signature richness you get at Costco. For the spices, Penzeys or bulk bins are worth it if you bake often, but the regular grocery store stuff is fine for a one-time pie. Toasting the spices in butter first? Game changer—it deepens their flavor and makes the whole pie smell like heaven. I always grab extra cinnamon and nutmeg since they’re used in so many holiday recipes.

No evaporated milk? Full-fat sweetened condensed milk works in a pinch, but cut it with a splash of heavy cream to mimic the texture. Running low on corn syrup? Honey or maple syrup does the trick, but reduce the sugar slightly since they’re sweeter. The vanilla extract matters—nothing but pure. If you’ve got a vanilla bean, scrape the seeds into your extract for extra depth. For the crust, Pillsbury pie crust is foolproof, but homemade tastes like you actually put in effort. No lattice skills? Cut the dough into strips and weave them over the filling—it’ll still look gorgeous.

This pie tastes even better the next day, so bake it a day ahead if you can. Store leftovers in the fridge for 4-5 days or freeze for 3 months. The crust stays crisp if you reheat slices at 350°F for 10 minutes. I always make two pies—one for now, one for later. The whipped cream? Whip it up fresh with a pinch of cinnamon and a drizzle of caramel for that full Costco experience.

Step-by-step instructions for Costco pumpkin pie copycat recipe

Here's how to nail that iconic Costco pumpkin pie filling and buttery lattice crust at home.

In a large mixing bowl, combine the 15 oz pumpkin puree, 1.5 cups granulated sugar, 0.25 cup corn syrup, 2 whole large eggs, and 1 cup evaporated milk. Whisk everything together until completely smooth—no lumps allowed. This is your base, and getting it silky now prevents graininess later.

Next, melt the 0.5 cup unsalted butter in a small saucepan over low heat. Once melted, remove from heat and let it cool slightly. Stir in the 2 tbsp ground cinnamon, 0.5 tsp ground nutmeg, 0.5 tsp ground cloves, 1 tbsp pure vanilla extract, and 0.5 tsp salt. This spice mixture is where the magic happens—those warm, cozy spices are what make this pie taste so familiar.

Slowly pour the melted spiced butter mixture into the pumpkin mixture while whisking constantly. This gradual addition keeps everything well incorporated. Keep whisking until the filling is completely smooth and homogeneous—it should look like a thick, creamy batter with no streaks of spice.

Taste a small spoonful and adjust sweetness if needed. I usually find this ratio just right, but if you prefer it sweeter, add a little more sugar. The filling should be sweet but still allow the spices to shine through. Once satisfied, transfer the filling to a medium bowl and set aside—it'll need to chill before baking.

Unroll the 1 package pie dough on a lightly floured surface. If it's too cold to work with, let it sit at room temperature for 10-15 minutes until pliable. Cut the dough into two equal rectangles—this will create the classic lattice pattern. Keep one rectangle whole and cut the other into 1-inch wide strips for the lattice top.

Roll out the whole dough rectangle and press it gently into a 9-inch pie dish, letting it extend slightly over the edges. Trim any excess dough hanging over the rim. Chill the crust in the fridge for 20 minutes while you prepare the filling for assembly. This chilling step prevents shrinking during baking and makes handling easier.

Pour the chilled pumpkin filling into the prepared pie crust, spreading it evenly. Arrange the 1-inch wide dough strips in a lattice pattern over the filling, starting with strips that run perpendicular to one another. Weave the strips together by placing one strip across two parallel strips, then alternating directions to create that beautiful crisscross pattern.

Trim any excess dough from the edges and crimp the crust to seal. Brush the lattice top with a little evaporated milk or heavy whipping cream to add a golden finish. Bake in a preheated 375°F oven for 50-55 minutes, or until the crust is golden brown and the filling is just set in the center. The edges should be bubbling slightly, but the center should still have a slight wobble when gently shaken.

While the pie is still warm, whip the 0.5 cup heavy whipping cream with a hand mixer until it forms soft peaks. Spread this lightly over the top of the pie before it cools completely—this adds that signature Costco touch and keeps the pie looking fresh.

Let the pie cool to room temperature before slicing. The filling should be perfectly spiced, smooth, and just set—not too firm, not too runny. Serve with a dollop of whipped cream on top if you like, and enjoy that familiar, comforting flavor that makes this pie so special.

Perfect pairings for these flavors

Classic Whipped Cream

No Costco pumpkin pie is complete without a dollop of whipped cream on top. I use 0.5 cup heavy whipping cream (like Whole Foods 365 or Cascade Creamery) whipped to soft peaks with a pinch of ground cinnamon for warmth.

For extra flair, drizzle with homemade caramel sauce—just simmer 1 cup sugar with 0.25 cup water and 2 tbsp butter until golden. 🍯

Vanilla Bean Ice Cream

For a creamy contrast, serve slices with vanilla bean ice cream like Blue Bell or Breyers. The cold sweetness cuts through the spiced filling beautifully. I like to add a sprinkle of toasted pecans or crushed gingersnaps on top for texture.

A scoop also makes this pie feel extra decadent—perfect for holiday gatherings. 🍦

Spiced Bourbon Drizzle

Elevate your pie with a bourbon-infused drizzle—simmer 0.5 cup brown sugar, 0.25 cup bourbon (like Maker’s Mark), and 2 tbsp butter for 5 minutes. Strain and drizzle over warm slices.

The caramelized bourbon adds depth that mimics Costco’s secret touch. Pair with a glass of bourbon or champagne for a festive finish. 🥃

Caramel Apple Topping

For a seasonal twist, top slices with caramelized apples. Thinly slice 1 apple, sauté in 1 tbsp butter with 0.5 tsp cinnamon until tender, then drizzle with store-bought caramel sauce.

The apple’s crispness balances the pie’s richness. This works especially well in fall when apples are at their peak. 🍎

Maple Walnut Crunch

Add a maple-walnut crumble for texture: Mix 0.25 cup chopped walnuts, 2 tbsp maple syrup, and 1 tbsp brown sugar, then bake at 350°F for 8 minutes until golden. Sprinkle over pie slices for a nutty, sweet contrast. This combo is a crowd-pleaser at Thanksgiving tables. 🌰

Coffee or Chai Pairing

Serve this pie with hot coffee or chai tea to enhance the spices. A dark roast like Peet’s Major Dickason’s Blend or a spiced chai latte from Starbucks complements the cinnamon and nutmeg perfectly. The warmth of the drink makes the pie taste even more comforting. ☕
