Fluffy Pumpkin Sheet Cake

This irresistibly moist yet fluffy Pumpkin Sheet Cake is quite literally takes the cake as my favorite pumpkin cake recipe! Just when I thought nothing could rival the marvellous flavor and texture of this Pumpkin Dream Cake, I fell head-over-apron for this quick and easy sheet cake recipe that’s packed full of pumpkin and spices, and absolutely delicious. Best of all, it’s ready in 30 minutes or less!

Inspired by classic Texas sheet cake, this homemade cake is made in a sheet pan and calls for savory pumpkin in place of chocolate cake and a rich, cinnamon cream cheese frosting in lieu of chocolate icing. The resulting cake is simply heavenly and perfect for fall gatherings – in flavor and in size!

What You’ll Need

The great pumpkin and spice flavors of this cake come together with a list of common ingredients (many overlap between the cake and the frosting!). Here’s what you’ll need to make this Pumpkin Sheet Cake with Cinnamon Frosting:

  • Pumpkin Puree: Either canned or freshly pureed pumpkin. Along with pumpkin flavor, the puree gives the cake crumb a rich, moist texture.
  • Flour: All-purpose flour (as opposed to cake flour) works best with a thick and wet batter like this one.
  • Pumpkin Pie Spice: Use premixed Pumpkin Pie Spice from your local supermarket, or make your own using the instructions in the “Tips” section!
  • Butter: For the cake and for the frosting. Use unsalted, melted butter for the batter, and softened butter for the frosting.
  • Milk: Whole milk does the trick, or use a dairy-free alternative. Whichever milk you choose for the cake, you’ll need it for the frosting as well!
  • Sugar: Keep the batter simple with granulated sugar, or use brown sugar for some extra depth of flavor!
  • Eggs: You’ll need 2 large eggs for this recipe.
  • Vanilla: Pure vanilla extract almost always offers the best flavor when baking. You’ll also need vanilla for the sweet, flavorful cinnamon frosting!
  • Cream Cheese: For the cream cheese frosting. The perfect pairing for pumpkin spice!
  • Cinnamon: The star ingredient in the frosting, alongside cream cheese; use fresh or pre-ground cinnamon for a hit of warmth and spice. 
  • Powdered Sugar: Confectioners’ sugar gives the frosting an irresistible, melt-in-your-mouth texture.

How to Make a Pumpkin Sheet Cake

The key to a sheet cake is the large, shallow pan. Like my White Texas Almond Sheet Cake and Chocolate and Peanut Butter Sheet Cake, one cake can serve a large number of friends and family, making these cakes the best for parties, potlucks, and sharing! Not to mention, this single-layer cake is incredibly easy to make — no assembly required! Here’s how you do it:

Prep the Sheet Pan: While your oven is preheating, grease a large sheet pan with a light coating of butter or cooking spray. I prefer to use a 13 x 18 inch jelly roll pan (also known as a baker’s half-sheet) for a thin, moist cake with the perfect frosting-to-cake ratio! You can use a 9 x 13 inch pan in a pinch, bearing in mind that the cake’s cooking time will increase to about 35 minutes.

Cream the Butter: In the microwave, melt the butter in short 10-15 second bursts. Whisk the melted butter together with the milk, pumpkin puree and sugar. In the same bowl, add in the eggs and vanilla extract and whisk until combined.

Combine the Dry Ingredients: Add the flour, baking soda, pumpkin pie spice and salt to the bowl with the batter. Combine these gradually and make sure everything is fully incorporated.

Bake: Spread the batter evenly into your prepared jelly roll pan. Bake until a toothpick inserted in the center comes out clean, about 20 minutes. This leaves plenty of time to whisk together the cream cheese frosting!

Make the Cinnamon Cream Cheese Frosting: Cream together the softened butter and cream cheese until it makes a smooth mixture. Slowly beat in the milk, vanilla extract and cinnamon until everything is combined. Finally, whisk in the powdered sugar. Turn the beater up to high and mix until the frosting is light and smooth! 

About this time is when the whole kitchen starts to fill with the warm smell of fall spices. Freshly baked pumpkin cake is one of my family’s favorite smells and just divine! 

Remove the sheet cake from the oven and spread the cinnamon frosting over the top while the cake is still warm. The frosting will melt into the cake as it cools – giving the cake the most finger-licking, crumbly soft taste and texture!

Tips for Success

Keep Refrigerated: Refrigerate the cake until you’re ready to serve. Before slicing, allow the cake to warm up on the counter for 10 minutes or so. 

Make Your Own Pumpkin Pie Spice: You can buy a premixed spice, or easily make your own! Combine 1 part each of the ground spices that make up the store bought version: cinnamon, ginger, nutmeg, cloves, and allspice.

How to Store a Frosted Cake

Sheet cake travels wonderfully, which is just one more reason why this is the ideal cake for gatherings. You can leave the cake in the sheet pan for transporting and serving!

If you have cake leftover, these slices can be stored in an air-tight container for 2-3 days. I recommend keeping the cake in the fridge for the freshest, longest-lasting results.

    Just finished making this cake for a church dinner tonight. It was easy to make and the frosting is delicious. I can’t wait to try it tonight.

    I absolutely love this recipe. I’m wondering, could this be made using mini bundt pans? I’m looking at making 3″ cakes.

  3. Delia B.

    I entered this cake at my grandsons parish picnic dessert contest and won $50!! We heard the judges say this was the best cake EVER!! It is truly a crowd pleaser!! Can’t go wrong making this cake!!

      That’s a personal choice! If you are going to serve the cake fresh, I will spread the cream cheese frosting on while the cake is still warm. However if you are making the cake to serve later, I would allow the cake to cool before frosting. Hope this helps!

  4. stella sanok

    In the video, it looked like you put in two teaspoons of vanilla, the recipe said one teaspoon of vanilla. Confused.

    Hi there! LOVE this recipe. I get so many compliments on it! I don’t know if my friends have noticed, but I can’t ever seem to get all of the cream cheese to blend. I can always see tiny little clumps. Do you recommend letting it soften at room temp, or mixing while cold? Any other ideas on why this is happening?

      Jessica

      Hi Lenzi! Yes, I can’t believe no one mentioned that before. I updated the recipe to say to let the butter and cream cheese soften. That will make it much smoother when you beat it and you won’t have those tiny lumps. 😉 

  6. Christine

    I am so let down. I followed recipe exactly and cake never rose. My baking soda was new. Don’t know what I did wrong. On a plus side the frosting came out beautifully just nothing to put it on now lol…

  7. Sky

    Heads up let the cake cool before applying the frosting. I didn’t because it wasn’t included in the directions and I ruined my cake 🙁 otherwise everything is delicious!

  8. Alice

    Made in a 13×9 pan and it didnt work out. Baked for a longer time and the outside ended up brown and hard as a rock while inside stayed soft with batter. Check it at 20. 25. And 30 minutes
