Ingredients

FOR THE CAKE

Granulated sugar: Granulated sugar is essential for achieving just the right texture and sweetness in your pumpkin spice cake. 

Canola oil: Adding oil to a cake is what gives you that super moist texture. If you don’t want to use oil, you can also use applesauce as a substitute.

Canned pumpkin puree: Pumpkin puree will provide moisture and of course the delicious pumpkin flavor that is the focus of these cake bars. Make sure you get 100% pumpkin puree and not pumpkin pie filling.

Eggs: Adding eggs helps give the spice cake bars a light and fluffy texture. Use room-temperature eggs in the batter to ensure they combine evenly throughout.

All-purpose flour: We normally use all-purpose flour when making these sheet pan pumpkin spice cake bars. However, they are also delicious if made with whole wheat flour! You can substitute with whole wheat flour in equal amounts if desired.

Baking soda: The baking soda balances out the acidity of the batter and provides additional leavening for the perfect light and fluffy sheet cake.

Baking powder: A little bit of baking powder goes a long way in helping a cake to rise. 

Ground cinnamon: Cinnamon is one of the primary spices in these pumpkin spice cake bars. The flavor pairs perfectly with pumpkin too!

Ground nutmeg: The unique flavor of nutmeg contributes a warm spice and compliments the cinnamon flavor.

Ground cloves: Cloves add an intense spice and slight bitterness that adds complexity and balances out the sweetness of these pumpkin cake bars.

FOR THE FROSTING

Cream cheese: Cream cheese adds rich creaminess and tang to the frosting. Cream cheese and pumpkin are a classic combination!

Butter: We like to use salted butter here but unsalted works great too. Just add a dash of salt to balance out the sweetness if you use unsalted butter.

Powdered sugar: Powdered sugar adds sweetness to the frosting and balances out the flavor of the cream cheese. Sift the powdered sugar to avoid any lumps in the frosting.

Pure vanilla extract: Vanilla extract adds another layer of flavor to the cream cheese frosting. You can never have too much vanilla!

Evaporated milk: The addition of evaporated milk creates an extremely rich, creamy, and velvety cream cheese frosting. If needed, you can substitute regular milk or heavy cream.

How To Make This Recipe

Start by preparing the ingredients. For the best results, make sure all of the ingredients are at room temperature. This allows the ingredients to bind together more easily for extra light and fluffy pumpkin spice cake bars.

Before you get started on the batter, preheat the oven to 375°F. Prepare a half-sheet pan (18”x13”) by lightly spraying it with non-stick cooking spray.

In a large mixing bowl – I like to use my KitchenAid mixer and paddle attachment – mix together the sugar, oil, and pumpkin.

Then, add the eggs one at a time, scraping down the sides of the bowl with a rubber spatula as needed.

Next, add in the flour, baking soda, baking powder, and spices and mix just until the ingredients are fully combined.

Pour the batter into the greased pan and spread it evenly with a rubber spatula.

Place the cake in the oven to bake for 25 minutes. Check the cake with a toothpick to ensure it's done before removing it from the oven. Set it aside to cool completely.

How To Make The Perfect Cream Cheese Frosting

In a medium mixing bowl, cream together the butter and cream cheese until smooth. Then, mix in the powdered sugar until combined. Be sure to scrape down the sides of the bowl with a rubber spatula as needed.

Finally, mix in the vanilla extract. Add the evaporated milk as needed to reach the desired consistency. Continue to mix until all of the ingredients are fully combined and the texture is smooth and creamy.

Once the pumpkin bars are cooled to room temperature, spread the cream cheese frosting evenly across the top. Cut the cake into squares, serve, and enjoy!

Recipe Tips and Tricks

Use pumpkin puree. Not to be confused with pumpkin pie filling, canned pumpkin puree is 100% pumpkin and does not have the added sugars and spices that are found in canned pumpkin pie filling. In this recipe, the spices are added separately for better flavor control.

Don’t overmix the batter. Mix the ingredients just until they are fully combined. Overmixing will make your bars dense and chewy.

Add nuts. Of course, this is totally optional, but adding some nuts to this pumpkin bar recipe really takes it to the next level. You can try adding chopped walnuts or pecans to the batter before baking or sprinkling them on top of the cream cheese frosting.

Let the bars cool before frosting. As tempting as it may be, don’t frost your pumpkin bars until they have cooled to room temperature, otherwise, your frosting will melt and become thin and runny instead of thick and creamy like you want!
