This pumpkin pie cake is a 9×13-inch baked dessert with a vanilla cake base and a spiced pumpkin filling that sinks into the batter as it bakes, giving you two distinct layers in one pan. It cuts into 12 generous slices, takes about 20 minutes to put together, and bakes in just over an hour. If you need a Thanksgiving dessert that feeds a crowd without requiring any special decorating skills, this is a solid choice.
The short version of why this works
Two things make this recipe work. First, the pumpkin filling is poured over the cake batter after it goes into the pan — not mixed in. Because the filling is denser than the batter, it sinks during baking and settles into the middle, creating a creamy layer without any extra effort. Second, creaming the softened butter and sugar for 3–4 minutes builds enough air into the batter to support that weight from above. Cut that step short and the cake base comes out flat and dense instead of light enough to hold the filling up at the edges.
Ingredient notes
- Pumpkin puree: Use plain canned pumpkin puree, not pumpkin pie filling. Pie filling already contains sugar and spices, which will throw off the balance of the filling entirely.
- Pumpkin pie spice: The recipe calls for 1½ teaspoons, which gives a noticeable but not sharp spice flavour — good for kids and anyone who finds heavily spiced desserts overwhelming. If your household likes a stronger spice hit, go up to 2 teaspoons.
- Whole milk: Used in both the cake batter and the filling. The filling calls for warmed milk — just 30 seconds in the microwave is enough. Cold milk can cause the filling to seize slightly when it hits the eggs.
- Butter: Must be softened to room temperature before you start. Cold butter will not cream properly and the batter will look curdled. Leave it out for about an hour, or cut it into cubes and leave it for 30 minutes.
Leftovers and make-ahead
Once fully cooled, cover the pan tightly with plastic wrap or transfer slices to an airtight container. It keeps well in the fridge for up to 4 days — the texture actually firms up nicely overnight, which makes it easier to slice cleanly. For make-ahead baking, you can bake the whole cake up to 2 days before serving; just dust with icing sugar on the day so it does not absorb into the surface. To freeze, wrap individual slices in plastic wrap and then foil and freeze for up to 6 weeks. Thaw overnight in the fridge. Skip reheating — this cake is best served at room temperature or cold straight from the fridge.
Mistakes to avoid
- Pouring the filling too fast or off-centre: If you dump the filling in one spot or pour it too quickly, it can push the batter to the sides unevenly. Pour slowly over the centre and let it spread on its own — do not spread it with a spatula.
- Opening the oven door early: The filling layer makes this cake more fragile than a standard cake while it is still setting. Do not open the oven before the 60-minute mark or the centre can sink and stay wet.
- Pulling it out before the edges are set: A toothpick in the centre will come out with some moist crumb because of the pumpkin layer — that is normal. Check the edges instead: they should be pulling away from the pan slightly and feel firm to a light touch.
- Skipping the pan prep: Both greasing and flouring the pan matter here. The pumpkin filling makes the bottom of the cake stickier than a plain cake. A greased-but-not-floured pan increases the chance of the first few slices tearing when you lift them out.
- Dusting with icing sugar while the cake is still warm: It melts straight in and disappears. Wait until the cake is fully cool — skip the garnish entirely if you are serving it straight from the fridge, since condensation will dissolve it anyway and it is not worth the extra dish.
Pumpkin Pie Cake: Easy Thanksgiving Dessert Recipe
Equipment
- 9×13-inch (33×23cm) baking pan
- Electric hand mixer or stand mixer with paddle attachment
- Large mixing bowl
- Medium mixing bowl
- Offset spatula
- Wire cooling rack
- Toothpick or cake tester
Ingredients
Cake Ingredients
- 2½ cups all-purpose flour
- 1 cup butter softened
- 1 cup whole milk
- 3 medium eggs
- 1½ cups granulated sugar
- 1 teaspoon kosher salt
- 2 teaspoons baking powder
- 2 teaspoons vanilla extract
- 1 teaspoon icing sugar (confectioners' sugar) for dusting
- additional as needed butter and flour for greasing and flouring the pan
Filling Ingredients
- 3 medium eggs
- 1 cup granulated sugar
- ⅔ cup whole milk warmed
- 1½ teaspoons pumpkin pie spice
- 15 ounces pumpkin puree unsweetened, one standard can
Instructions
Filling Instructions
- In a medium bowl, whisk together the eggs, sugar, warmed milk, pumpkin pie spice, and pumpkin puree until completely smooth. Set aside.
Cake Instructions
- Preheat the oven to 350°F / 175°C (160°C fan-forced).
- Grease and flour a 9×13-inch (33×23cm) baking pan and set it aside.
- Now in a bowl, whisk flour, baking powder, and salt.
- In a large bowl, beat the softened butter and granulated sugar with an electric mixer on medium-high speed until light and fluffy, about 3–4 minutes.
- Scrape down the sides of the bowl and beat in egg one at a time until incorporated.
- Then beat in vanilla.
- Now add 1⁄3 of the flour mixture to the egg mixture and beat it until they are combined.
- Scrape down the sides and add ½ of the milk.
- Beat it again until combined and carry on repeating alternating with the flour and milk, ending it finally with 1⁄3 of the flour.
- Now, scrape the batter with an offset spatula into the prepared pan by smoothing it.
- Gently pour the pumpkin filling over the centre of the cake batter. Do not stir or spread — the filling will distribute and sink into the batter as it bakes.
- Bake the cake mixture for about 70 to 75 minutes or until the cake turns golden brown and the pumpkin filling no longer jiggles.
- Let the cake cool in the pan on a wire cooling rack for at least 30 minutes. The pumpkin layer will continue to set as it cools. Once cooled, dust with icing sugar and serve. Refrigerate any leftovers.
Notes
Notes
- Storage: Cover tightly and refrigerate for up to 4 days. The pumpkin filling layer means this cake must be refrigerated — do not leave at room temperature for more than 2 hours.
- Freezing: Wrap individual slices in cling film and freeze for up to 2 months. Thaw overnight in the fridge.
- Make-ahead: Bake the cake up to 2 days ahead and refrigerate. Dust with icing sugar just before serving for the freshest presentation.
- Pro tip: Bring your butter, eggs, and milk to room temperature before starting. Room-temperature ingredients emulsify more easily, producing a lighter, more tender crumb.
- Substitution: Swap the whole milk for buttermilk for a slightly tangier cake with an even softer texture. Reduce baking powder to 1½ teaspoons if using buttermilk.

Frequently asked questions
Can I use a different size pan?
A 9×13-inch pan is strongly recommended for this recipe. A smaller pan means the batter will be deeper, the filling will not spread evenly, and the bake time will need to increase — making it harder to judge doneness without overbaking the edges.
Can I make this without a mixer?
Not easily, no. The creaming step — beating softened butter and sugar until light and fluffy — requires sustained mixing that is very difficult to achieve by hand. A hand mixer is the minimum; a stand mixer works just as well.
Will the pumpkin filling taste eggy?
No — the finished filling tastes like a mild, lightly spiced pumpkin custard rather than anything eggy. The three eggs in the filling are what help it set into a creamy layer rather than staying wet, but their flavour is not detectable in the baked result.
