How to Make Pumpkin Slab Pie

Step 1 – Prepare the Crust

Start with a large bowl and whisk together the flour, sugar, and salt. I like to use my hands for this next part: cut in the cold butter until the mixture feels like coarse sand. Think beach day, but make it buttery.

Add ice water one tablespoon at a time, gently mixing until the dough holds together. Don’t overwork it—just enough so it’s not crumbly. This crust is the foundation of your sheet pan pumpkin pie, so treat it with care.

Step 2 – Roll Out and Fit the Dough

Lightly flour your surface and roll the dough into a rectangle that fits a 10×15-inch jelly roll pan. I always roll a little larger than I need, then trim the edges once it’s in the pan.

Carefully lift and press the dough into the corners and sides. Crimp the edges however you like—rustic is totally charming for this pumpkin pie bars large batch style dessert.

Step 3 – Chill the Crust

Pop the crust into the fridge for 15 minutes. This step helps it hold its shape in the oven and keeps it ultra flaky. If you’re in a mad rush (been there!), even 10 minutes helps.

Chilling also gives you a breather to prep the filling for your easy pumpkin slab pie recipe.

Step 4 – Make the Pumpkin Filling

In a separate bowl, whisk together the pumpkin purée, brown sugar, eggs, evaporated milk, spices, vanilla, and a pinch of salt. The mixture should be silky and smooth, like pumpkin custard sunshine.

I always taste-test a tiny bit here (yes, even raw)—just to make sure those warm spices are balanced. This is where your fall pumpkin dessert for a crowd gets its signature flavor.

Step 5 – Fill and Bake

Pour the filling into your chilled crust and spread it evenly with a spatula. It should look like a cozy orange blanket tucked into bed.

Bake at 375°F for 35 to 40 minutes. The center should be just set with a slight jiggle—like Jell-O on its best behavior. That’s how you know it’s ready.

Step 6 – Cool and Finish with Whipped Cream

Let the pie cool completely in the pan. This part tests my patience every time, but trust me—it slices cleaner and tastes even better when cooled.

Right before serving, top with a generous layer of whipped cream and maybe a dash of cinnamon. That’s your showstopper moment. This is the pumpkin slab pie with whipped cream your holiday table will remember.

Tips for Success

• Keep your butter cold for the flakiest crust—pop it in the freezer for 10 minutes if needed.
• Use parchment paper under the crust to prevent sticking and make cleanup easier.
• Don’t skip chilling the dough—it helps the crust keep its shape.
• Let the pie cool fully before slicing for perfect pumpkin pie squares every time.
• Top just before serving to keep whipped cream fresh and fluffy.

Equipment Needed

• Mixing bowls – One for the crust, one for the filling. Any sturdy bowl will do the trick.
• Pastry cutter or forks – To cut in cold butter. Or just use your fingers like I do!
• Rolling pin – A wine bottle works in a pinch (been there, done that).
• 10×15-inch jelly roll pan – This is key for that classic sheet pan pumpkin pie shape.
• Whisk and spatula – For smooth filling and easy spreading.
• Measuring cups and spoons – So every spice hits just right.

Variations

• Gluten-Free Pumpkin Slab Pie – Swap the all-purpose flour for a 1:1 gluten-free blend. Just make sure it includes xanthan gum for structure.
• Dairy-Free Delight – Use plant-based butter and coconut or oat milk in place of evaporated milk. It still turns out creamy and rich.
• Maple Pecan Twist – Add 1/4 cup of maple syrup to the filling and sprinkle chopped toasted pecans on top before baking.
• Gingersnap Crust – Skip the rolled dough and press in a crust made from crushed gingersnap cookies and melted butter. Adds a spicy crunch!
• Mini Pumpkin Pie Squares – Cut into smaller bite-sized pieces and top each with a swirl of whipped cream for party-perfect pumpkin pie bars large batch style.
• Chocolate Drizzle Finish – Once cooled, drizzle melted dark chocolate over the top for a decadent touch. It’s a fun spin on holiday pumpkin desserts.

Serving Suggestions

• Pair with hot apple cider or a spiced chai latte for cozy autumn vibes.
• Serve chilled or at room temp with a dollop of whipped cream and cinnamon dust.
