This ultra-moist pumpkin sheet cake is packed with cozy spices and topped with a velvety cream cheese frosting. The ultimate easy autumn Desserts.
- Oil-Based Crumb: Using vegetable oil instead of butter prevents gluten development, keeping the cake incredibly soft and moist even after days in the fridge.
- Pectin Power: Pumpkin puree is naturally high in pectin, which acts as a structural binder and moisture-retentive agent for a tender texture.
- Balanced Sweetness: A mix of brown and white sugars provides deep molasses notes without overwhelming the delicate warmth of the spices.
I remember standing over my kitchen counter last October, scraping the last stubborn bits of orange puree from a metal can while my wrist throbbed from hand-whisking a double batch of batter. The air was thick with cinnamon, and my old glass baking dish was already warm from the preheating oven. That afternoon, I realized that pumpkin cake shouldn't be a fussy, multi-tiered project; it is at its absolute best when kept simple, baked in a single pan, and slathered with an unapologetically thick layer of tangy frosting.
It is hands down my favorite autumn ritual.
Unlike traditional cakes that rely heavily on creamed butter to trap air, this recipe uses vegetable oil to guarantee a crumb that remains incredibly soft even when chilled. Pumpkin puree is packed with pectin and soluble fiber, which work alongside the oil to disrupt the protein matrix, ensuring the cake never turns tough or bready. If you love these warm spices but want something smaller for breakfast, you might also enjoy our pumpkin cream cheese muffins.
A common pitfall is using "pumpkin pie filling" instead of pure pumpkin. The former is pre-sweetened and watered down, which completely throws off the liquid-to-dry ratio and leaves you with a gummy center.
For the salt, I always reach for Diamond Crystal kosher salt — where 1 teaspoon equals roughly ½ teaspoon of standard table salt — because its light, hollow flakes dissolve instantly into the wet ingredients without leaving salty pockets. When it comes to the pan, a classic 9x13-inch metal baking pan provides sharper corners and more even heat distribution than glass, which can sometimes cause the edges to overbake before the middle is set. If you prefer a different format, this batter can also be adapted into a stunning super moist spice cake style layer cake.
When you pull it from the oven, the top should have a dull, matte finish and spring back gently when pressed. The aroma of toasted cinnamon and nutmeg will literally fill every corner of your home.
Ultimate Spiced Pumpkin Cake
Ingredients
- 2 cups (250g) all-purpose flour, spooned and leveled
- 2 teaspoons baking powder
- 1 teaspoon baking soda
- 1 teaspoon fine salt
- 1 and 1/2 teaspoons ground cinnamon
- 2 teaspoons store-bought or homemade pumpkin pie spice
- 1 cup (240ml) canola or vegetable oil
- 4 large eggs, room temperature
- 1 cup (200g) packed light or dark brown sugar
- 1/2 cup (100g) granulated sugar
- 1 can (15-ounce / 425g) pure pumpkin puree
- 1 and 1/2 teaspoons pure vanilla extract
- 8 ounces (226g) full-fat brick cream cheese, softened to room temperature
- 1/2 cup (8 tablespoons / 113g) unsalted butter, softened to room temperature
- 3 cups (360g) confectioners' sugar (plus an extra 1/4 cup if needed to thicken)
- 1 teaspoon pure vanilla extract
- 1/8 teaspoon fine salt
Directions
- Adjust your oven rack to the middle position and preheat to 350°F (177°C). Lightly grease a 9x13-inch baking pan with nonstick spray or butter.
- In a large mixing bowl, vigorously whisk together the flour, baking powder, baking soda, salt, cinnamon, and pumpkin pie spice until no clumps remain.
- In a separate medium bowl, whisk the oil, room-temperature eggs, brown sugar, granulated sugar, pumpkin puree, and vanilla extract until the mixture is completely smooth and emulsified.
- Pour the wet mixture directly into the dry ingredients. Using a sturdy spatula or whisk, fold the ingredients together just until the flour disappears and a thick, uniform batter forms.
- Spread the batter evenly into your prepared baking pan, smoothing the top with an offset spatula. Bake for 30 to 36 minutes, or until a toothpick inserted into the center comes out clean. If the top browns too quickly, tent it loosely with aluminum foil during the last 10 minutes.
- Transfer the pan to a wire rack and let the cake cool completely. To speed things up, you can slide the pan into the refrigerator after 45 minutes of cooling on the counter.
- Prepare the frosting: In a large bowl using a handheld or stand mixer fitted with the paddle attachment, beat the softened cream cheese and butter on high speed for about 2 minutes until completely smooth and creamy.
- Turn the mixer to low and gradually add the confectioners' sugar, vanilla, and salt. Once incorporated, increase the speed to high and beat for 2 full minutes until fluffy. If the frosting feels too soft, beat in the remaining 1/4 cup of sugar.
- Spread the frosting evenly over the cooled cake. Chill the frosted cake in the refrigerator for 30 minutes before slicing; this helps the frosting set cleanly and prevents tearing.
Notes
Keep these essential baking tips in mind for the absolute best results:
- Pumpkin Selection: I highly recommend Libby's canned pumpkin puree. If you use fresh homemade puree, blot it thoroughly with paper towels to remove excess water, which can interfere with starch gelatinization and make the cake dense.
- Salt Conversion: This recipe specifies fine salt. If using Diamond Crystal kosher salt, increase the amount to 1 and 1/2 teaspoons in the cake batter to maintain the correct flavor balance.
- Temperature Warning: Ensure your cream cheese and butter are truly at room temperature (around 65-68°F) before beating. If they are too cold, the frosting will be lumpy; if too warm, it will break and turn greasy.
- Preventing Dry Edges: Keep a close eye on the oven during the final 10 minutes. If your oven runs hot, the sugar in the pumpkin can caramelize too quickly on the edges; loosely tenting with foil protects the top from scorching.
- Alternative Pan Sizes: You can easily adapt this batter into cupcakes. Fill liners 2/3 full and bake at 350°F for 18-21 minutes.
Serving Suggestions
Elevate your Desserts presentation with these simple, texture-enhancing pairings:
- Pair a slice with a hot mug of black coffee to cut through the rich, sweet tang of the cream cheese frosting.
- Scatter toasted, salted pecans over the top of the frosting just before serving to add a satisfying, buttery crunch.
- Serve alongside a scoop of vanilla bean ice cream to contrast the warm, spiced cake with a cold, creamy melt.
- Drizzle a spoonful of warm caramel sauce over each plate to complement the deep molasses notes of the brown sugar.
- Enjoy a slice after a hearty autumn dinner like vegetarian pumpkin chili for the ultimate cozy night in.
Storage and Reheating
Because of the high moisture content in the pumpkin puree and the dairy in the cream cheese frosting, this cake must be stored in the refrigerator. Wrap the pan tightly with plastic wrap or transfer individual slices to an airtight container. It will keep beautifully for up to 5 days, and honestly, the spices deepen and meld together even better after 24 hours.
If you want to freeze the cake, it is best done unfrosted. Wrap the cooled, naked cake slab in a double layer of plastic wrap followed by a sturdy layer of aluminum foil, then freeze for up to 3 months. When you are ready to serve, thaw the cake overnight in the refrigerator, allow it to come to room temperature on the counter, and then whip up a fresh batch of frosting to spread over the top.
You can also freeze individual frosted slices. Place the slices on a baking sheet for an hour to flash-freeze the frosting, then wrap them tightly. They thaw surprisingly well on the counter in about 30 minutes, though the frosting might lose a touch of its original fluffiness.
Never microwave a frosted slice.
Ingredient Substitutes
If you need to adapt this recipe for dietary needs or pantry limitations, try these tested swaps:
- Canola Oil → Unsweetened Applesauce: Substitute half of the oil (1/2 cup) with 1/2 cup (90g) of unsweetened applesauce. This reduces the fat while maintaining moisture, though you should fold the batter extra gently to avoid overworking the gluten.
- Pumpkin Pie Spice → Individual Spices: If you don't have the pre-mixed spice, swap the 2 teaspoons of pumpkin pie spice for 1/2 teaspoon each of ground ginger, ground nutmeg, ground cloves, and ground allspice. Whisk them thoroughly into the flour to prevent spice clumps.
- All-Purpose Flour → 1-to-1 Gluten-Free Flour: Swap the 2 cups of all-purpose flour for an equal amount (250g) of a high-quality 1-to-1 gluten-free baking blend containing xanthan gum. Let the batter rest for 10 minutes before baking to allow the rice flour to fully hydrate.
- Cream Cheese → Mascarpone: Swap the 8 ounces of cream cheese for 8 ounces of mascarpone cheese for a richer, less tangy frosting. Reduce the mixing time slightly, as mascarpone can split if overbeaten.
- Brown Sugar → Coconut Sugar: Replace the 1 cup of brown sugar with 1 cup of coconut sugar. The cake will have a slightly more caramelized, rustic flavor, but you may need to whisk the wet ingredients for an extra minute to ensure the granules dissolve.
There is something incredibly comforting about a simple sheet cake waiting in the fridge for late-night snacking. It is the kind of Desserts that does not demand perfection, yet always delivers exactly what you want on a crisp autumn evening.
