Why You Will Love This Pumpkin Sheet Cake

There are plenty of reasons this easy pumpkin cake deserves a place on your fall baking list:

• It uses one full can of pumpkin puree.
• Oil keeps the cake soft, even after refrigeration.
• Brown sugar adds moisture and a mild caramel flavor.
• The spices are warm but do not overpower the pumpkin.
• The cake is baked in one pan with no layers to assemble.
• Cream cheese frosting adds just enough tang to balance the sweetness.
• It can be baked and frosted ahead of time.
• One cake can serve 15 to 20 people, depending on how you cut it.
  The cake has a tender crumb that holds together when sliced. It is moist enough to serve straight from the refrigerator, but it is not so dense that it feels like pumpkin bread.

What Makes This the Best Pumpkin Sheet Cake?

A good pumpkin cake needs more than a spoonful of pumpkin pie spice. The pumpkin, sugar, oil, eggs, flour, and leavening all need to work together so the cake rises properly and remains soft.
This recipe uses an entire 15-ounce can of pumpkin puree for a clear pumpkin flavor and plenty of natural moisture. A combination of brown sugar and granulated sugar gives the cake sweetness without making it taste flat. Brown sugar also helps create a softer crumb.
Vegetable oil is used instead of melted butter because pumpkin cakes tend to stay softer when made with oil. Butter brings flavor, but it can firm up once the cake is refrigerated. Since cream cheese frosting needs to stay chilled, oil is the better choice here.
A small amount of buttermilk loosens the batter and helps create a lighter texture. It also works with the baking soda to give the cake a good rise.
Finally, the spice mixture is added in separate amounts instead of relying only on pumpkin pie spice. That gives you better control over the cinnamon, ginger, nutmeg, and cloves.

Pumpkin Sheet Cake or Pumpkin Bars?

Pumpkin sheet cake and pumpkin bars can look similar, especially when both are baked in rectangular pans and covered with cream cheese frosting. The main difference is usually the texture.
Pumpkin sheet cake is light, soft, and cakey. It contains enough flour and leavening to produce a fluffy crumb that springs back when gently pressed.
Pumpkin bars are often thinner, denser, and sometimes slightly fudgy. Depending on the recipe, they may contain less flour or be baked in a larger sheet pan.
This recipe is a true cake. It rises above the edge of a thin bar and can be cut into generous dessert squares.

Ingredients You Will Need

For the Pumpkin Cake

• All-purpose flour: Gives the cake enough structure while keeping the crumb tender.
• Baking powder and baking soda: The combination helps the thick pumpkin batter rise evenly.
• Salt: Keeps the cake from tasting overly sweet and brings out the spices.
• Ground cinnamon: Supplies the main warm spice flavor.
• Ground ginger: Adds a gentle warmth that works well with pumpkin.
• Ground nutmeg: Gives the cake a familiar fall baking flavor.
• Ground cloves: A small amount adds depth. Too much can overpower the cake, so measure carefully.
• Pumpkin puree: Use plain canned pumpkin puree, not pumpkin pie filling.
• Brown sugar: Adds moisture and a mild molasses flavor.
• Granulated sugar: Sweetens the cake without making the crumb too dense.
• Eggs: Give the cake structure and help bind the batter.
• Vegetable oil: Keeps the pumpkin sheet cake moist for several days.
• Buttermilk: Helps soften the crumb and thin the batter.
• Vanilla extract: Rounds out the pumpkin and spice flavors.

For the Cream Cheese Frosting

• Block cream cheese: Use full-fat cream cheese sold in a brick. Cream cheese from a tub is softer and can make the frosting loose.
• Unsalted butter: Helps the frosting hold its shape and makes it easier to spread.
• Powdered sugar: Sweetens and thickens the frosting.
• Vanilla extract: Adds a warm bakery-style flavor.
• Salt: Balances the powdered sugar and cream cheese.

Pumpkin Puree Versus Pumpkin Pie Filling

Pumpkin puree and pumpkin pie filling are not interchangeable.
Pumpkin puree contains cooked, pureed pumpkin without added sugar or spices. It lets you control the sweetness and seasoning in the cake.
Pumpkin pie filling already contains sugar, spices, and other ingredients. Using it in this recipe can make the cake too sweet and may change the texture.
Check the front and back of the can before adding it to your batter. The ingredient list should say pumpkin and nothing else.

How to Make Pumpkin Sheet Cake with Cream Cheese Frosting

1. Prepare the Pan

Preheat the oven to 350°F. Lightly grease a 9-by-13-inch metal baking pan, then line it with parchment paper.
Leave a little parchment hanging over two sides of the pan if you want to lift out the entire cake before slicing. If you plan to serve it directly from the pan, a light coating of nonstick baking spray is enough.

2. Mix the Dry Ingredients

In a medium bowl, whisk together the flour, baking powder, baking soda, salt, cinnamon, ginger, nutmeg, and cloves.
Whisking the dry ingredients before adding them to the batter spreads the leavening and spices throughout the flour. This helps prevent bitter pockets of baking soda or clumps of cinnamon.

3. Combine the Wet Ingredients

In a large mixing bowl, whisk together the pumpkin puree, brown sugar, granulated sugar, eggs, oil, buttermilk, and vanilla.
Continue whisking until the eggs are fully blended and no streaks of brown sugar remain. The mixture should look smooth and glossy.

4. Finish the Batter

Add the dry ingredients to the pumpkin mixture. Fold or whisk gently just until the flour disappears.
Scrape the bottom and sides of the bowl so no dry flour remains, but stop mixing as soon as the batter is combined. Mixing too long after adding the flour can make the cake rubbery.

5. Bake the Cake

Pour the batter into the prepared pan and spread it into an even layer. Tap the pan gently against the counter once or twice to release large air pockets.
Bake for 32 to 38 minutes. Begin checking the cake at 30 minutes since ovens and baking pans can vary.
The pumpkin cake is ready when:

• The center springs back after a light touch.
• A toothpick inserted in the center comes out clean or with a few moist crumbs.
• The edges have begun to pull slightly away from the pan.
  Do not wait for the toothpick to look completely dry. A bone-dry toothpick can mean the cake has already baked too long.

6. Cool Completely

Place the pan on a wire rack and let the pumpkin cake cool completely before frosting it.
This can take about two hours. Spreading cream cheese frosting over a warm cake will cause the butter and cream cheese to melt.

7. Make the Cream Cheese Frosting

Beat the softened butter with an electric mixer for about one minute, until smooth and creamy. Add the cream cheese and beat on medium speed just until combined.
Add the powdered sugar one cup at a time, mixing on low speed after each addition. Add the vanilla and salt, then beat briefly until smooth and fluffy.
Avoid beating cream cheese frosting for several minutes on high speed. Overmixing can make it loose and difficult to spread.

8. Frost and Serve

Spoon the cream cheese frosting over the cooled cake. Use an offset spatula or the back of a spoon to spread it to the edges.
Create soft swirls in the frosting, then add chopped pecans, cinnamon, or fall sprinkles if desired. Chill the frosted cake for 30 minutes before cutting if you want especially neat slices.

Tips for a Moist Pumpkin Sheet Cake

Measure the Flour Correctly

Adding too much flour is one of the most common reasons a homemade cake turns out dry.
For the best results, weigh the flour with a kitchen scale. If you are using measuring cups, spoon the flour into the cup and level the top with a straight edge. Do not scoop the flour directly from the bag because it can become tightly packed.

Do Not Drain the Pumpkin

Canned pumpkin puree can look thick, but you do not need to strain or drain it for this recipe. Its moisture is already accounted for in the batter.

Use Room-Temperature Ingredients

Room-temperature eggs and buttermilk blend more easily into the pumpkin mixture. This creates a smoother batter and helps the cake bake more evenly.
If you forgot to set out the eggs, place them in a bowl of warm water for five to ten minutes.

Mix Only Until Combined

Once the flour is added, mix the batter gently. Overmixing develops too much gluten, which can give the finished cake a tough or chewy crumb.

Check Your Cake Early

A metal pan usually bakes faster than a glass or ceramic dish. Begin checking the cake several minutes before the listed baking time ends.

Let the Cake Cool Before Frosting

The cake must be completely cool. Even a slightly warm center can soften the frosting and cause it to slide.

How to Make Cream Cheese Frosting That Is Not Runny

Cream cheese frosting can become loose when the ingredients are too warm or mixed for too long. These tips will help it stay thick and spreadable:

• Use full-fat block cream cheese rather than whipped or tub-style cream cheese.
• Let the cream cheese soften, but do not allow it to become warm.
• Beat the butter first before adding the cream cheese.
• Mix the butter and cream cheese only until smooth.
• Add powdered sugar gradually.
• Chill loose frosting for 20 to 30 minutes before spreading.
• Wait until the cake is completely cool.
  If your kitchen is warm, refrigerate the frosted cake shortly after decorating it.

Easy Pumpkin Sheet Cake Toppings

The frosting swirls are pretty on their own, but a simple topping can dress up the cake for a party or holiday table.
Try one of these ideas:

• Toasted chopped pecans
• Chopped walnuts
• A light dusting of cinnamon
• A pinch of pumpkin pie spice
• Orange and gold fall sprinkles
• Small candy pumpkins
• A thin drizzle of salted caramel
• Finely grated orange zest
• White chocolate curls
  Add crunchy toppings shortly before serving if you want them to remain crisp.

Can I Make This Cake in a Different Pan?

Yes, but the baking time will need to be changed.

10-by-15-Inch Jelly Roll Pan

The cake will be thinner and may bake in about 22 to 28 minutes. Watch it carefully near the end of baking.

13-by-18-Inch Half Sheet Pan

This recipe will produce a very thin cake in a half sheet pan. For a thicker party-size cake, prepare one and a half batches. Make sure the sides of the pan are high enough to hold the batter.

Two 8-Inch Round Pans

Divide the batter evenly between two greased and parchment-lined pans. Begin checking around 25 minutes. Cool the layers before removing them from the pans.

Cupcakes

Fill lined cupcake wells about two-thirds full. Bake at 350°F for approximately 18 to 22 minutes. This recipe should make around 20 to 24 cupcakes.

Pumpkin Cake Variations

Maple Cream Cheese Frosting

Replace one teaspoon of vanilla with one teaspoon of maple extract. Maple extract gives the frosting a stronger maple flavor without thinning it with extra syrup.

Brown Butter Frosting

Brown the butter, let it return to a soft solid texture, and then use it in the frosting. The toasted flavor pairs beautifully with pumpkin and pecans.

Pumpkin Pecan Sheet Cake

Fold ¾ cup of toasted chopped pecans into the finished batter. Sprinkle more pecans over the frosting before serving.

Pumpkin Chocolate Chip Cake

Fold one cup of mini chocolate chips into the batter. Toss them with a teaspoon of flour first to help keep them evenly distributed.

Raisin and Walnut Pumpkin Cake

Add ½ cup of raisins and ½ cup of chopped walnuts. This creates a cake with a texture similar to carrot cake.

Less-Sweet Frosting

Start with three cups of powdered sugar. Add more only if the frosting needs additional thickness.

What to Serve with Pumpkin Sheet Cake

This cake is rich enough to stand on its own, but it also pairs well with:

• Freshly brewed coffee
• Hot tea or chai
• Apple cider
• Cold milk
• Vanilla ice cream
• Cinnamon ice cream
• Sliced apples or pears
• A spoonful of salted caramel sauce
  For Thanksgiving, I like cutting the cake into smaller squares so guests can enjoy it alongside other desserts.

How to Cut Clean Cake Squares

For neat slices, refrigerate the frosted cake for at least 30 minutes. Use a long, sharp knife and wipe the blade clean after each cut.
Cut the cake into 15 large squares for generous dessert servings or 20 smaller squares for a party tray. If several desserts are being served, you can cut it into 24 small pieces.

Make-Ahead Instructions

Pumpkin sheet cake is a great make-ahead dessert because the pumpkin and oil help it stay moist.

One Day Ahead

Bake and cool the cake, add the cream cheese frosting, cover the pan, and refrigerate overnight. Let it sit at room temperature for about 20 minutes before serving.

Two Days Ahead

Bake the cake, cool it completely, and cover the unfrosted pan tightly. Refrigerate the frosting in a separate airtight container. Frost the cake the day you plan to serve it.

Freezer Preparation

Freeze the cooled, unfrosted cake for the cleanest results. Wrap the cake in plastic wrap and a layer of foil, then freeze it for up to three months.
Thaw it overnight in the refrigerator and frost it after it has thawed.

How to Store Pumpkin Sheet Cake

Because the frosting contains cream cheese, the finished cake should be refrigerated.
Cover the baking pan tightly or place individual slices in an airtight container. Refrigerated pumpkin cake will remain fresh for up to five days.
The cake tastes good cold, but the crumb and frosting become softer if each slice rests at room temperature for 15 to 20 minutes before serving.
Do not leave the frosted cake at room temperature for longer than two hours.

Can You Freeze Frosted Pumpkin Cake?

Yes. Place individual slices on a parchment-lined baking sheet and freeze until the frosting feels firm. Wrap each frozen slice in plastic wrap, then place the pieces in a freezer-safe container.
Freeze for up to two months. Thaw the wrapped slices overnight in the refrigerator. Remove the wrapping after thawing so it does not pull frosting away from the cake.

Common Pumpkin Cake Mistakes

The Cake Is Gummy

A gummy center can be caused by underbaking, adding too much pumpkin, measuring too little flour, or cutting the cake before it has cooled.
Make sure you use a 15-ounce can of pumpkin and check the center with a toothpick before removing the cake from the oven.

The Cake Is Dry

Dry cake is usually caused by too much flour or too much time in the oven. Use a kitchen scale if possible and begin checking the cake early.

The Cake Sank in the Middle

The center can sink if the oven door is opened too soon, the cake is underbaked, or the baking powder and baking soda are old.
Wait until the cake has mostly set before opening the oven door.

The Frosting Is Sliding Off

The cake may still be warm, or the frosting may have become too soft. Refrigerate the frosting until it firms up and make sure the cake is cool before trying again.

The Spices Taste Bitter

Too much ground clove or old spices can create a bitter flavor. Measure cloves carefully and replace spices that smell dusty or stale.
