Pumpkin sheet cake made in a quarter sheet cake pan. Topped with the best pumpkin spice frosting made on the stove!

Have you seen my pumpkin ebook for 25 pumpkin recipe that aren’t pie and 1 that is? I think you would love it.



Pumpkin sheet cake:

I always hesitate before sharing my quarter sheet cake recipes, because they clearly serve more than two.

However, a quarter sheet cake recipe makes significantly less cake than a standard giant sheet cake, so I think we’re good. My goal is smaller desserts and less desserts, not just two single pieces of dessert, you know? I hope you’re with me!

Have you seen my Texas Chocolate Quarter Sheet Cake? We absolutely love it, and bake it often. I included a White Texas Sheet Cake recipe in my 3rd cookbook, Sweet & Simple: Dessert for Two.

It’s time for the pumpkin sheet cake version!

First, I feel like I should really say THANK YOU. There was a time in my life when I didn’t like pumpkin. It had to do with an incident in college with raw pumpkin, and I avoided pumpkin for years afterwards.

However, over the 8 years of writing this blog, I always make an effort to include a few pumpkin recipes for you each year. Slowly, over time, I’ve started to actually like pumpkin–all thanks to you!


Some of your favorite pumpkin recipes from this site are:
Pumpkin Nutella Muffins
Pumpkin Cinnamon Rolls
Pumpkin Chocolate Chip Cookies
Pumpkin Cakes for Two
Pumpkin Gnocchi
Pumpkin Swirl Brownies
Pumpkin Donut Holes
Pumpkin Chocolate Cupcakes
Pumpkin Snickerdoodles
Pumpkin Gooey Butter Cake

Oops, I think I listed nearly all of them. The point is, a lot of recipes have come before this one that makes me finally ready to appreciate a real pumpkin cake!


A pumpkin Sheet Cake with pumpkin spice frosting!

The pumpkin recipes I’ve shared so far on this site are so good that I don’t even mind that they contain pumpkin. While you’ll never catch me gobbling up a plain piece of pumpkin pie, you can occasionally find me reaching for my Orange Spiced Coconut Pumpkin Pie.

Overtime, I’ve noticed that I’ve become more okay with pumpkin. It started slowly with my homemade pumpkin spice latte (naturally), and it stayed that way for years. But this year, I think I’m ready for more vegan pumpkin muffins! Pumpkin sheet cake! And all the pumpkin desserts for two!


We’ve come a very long way, friends.

Thanks for being patient with me, and teaching me to love pumpkin, even if I only love it with gobs of sugar and spices, I appreciate you.

I dedicate this pumpkin quarter sheet cake to you!

How big is a quarter sheet cake?

I’m so glad you asked! The quarter sheet cake pan that I use measures roughly 9″ x 13″ x 1″. This is the exact pan that I use. I own two, and I use them frequently for roasting small batches of vegetables.


How many people does a quarter sheet cake feed?

If you glimpse at the photo, you can see that you get 12 small pieces of cake from this pumpkin sheet cake recipe. I would bake a quarter sheet cake for a dinner party of 4 to 6 people. You might not have any leftover, but no one will miss dessert either!

This pumpkin sheet cake recipe uses just 3/4 cup of pumpkin, leaving you with one full cup leftover from the can with which to bake another pumpkin dessert for two. You’ll also have al leftover egg yolk, as this recipe only uses the egg white. Browse my recipes that use egg yolks only.


I hope you enjoy this pumpkin sheet cake, but I really hope you enjoy the pumpkin spice frosting! I like to make my own pumpkin spice mix (1 tablespoon cinnamon, 2 teaspoon ground ginger, 1 teaspoon nutmeg, 1/2 teaspoon ground cloves, 1/2 teaspoon ground allspice, and 1/2 teaspoon finely ground black pepper), and use it here.

While you’re making the frosting on the stovetop, it’s an excellent time to practice your browned butter skills! Since the butter melts alone before any other ingredients are added, go ahead and practice browning it. If at any point you get scared you’re going to burn it, just add the milk and powdered sugar and continue! It’s like an optional browned butter frosting situation here, friends. It’s excellent with browned butter, but it’s amazing without it, too.

Yield: 1 quarter sheet cake

Pumpkin Sheet Cake


One bowl pumpkin sheet cake with pumpkin spice frosting.

Prep Time 15 minutes
Cook Time 17 minutes
Total Time 32 minutes


  • 1 cup all-purpose flour
  • 1 cup granulated sugar
  • 1/8 teaspoon salt
  • 5 tablespoons unsalted butter, melted
  • 1/2 cup buttermilk
  • 1 large egg white (yolk removed)
  • 3/4 cup canned pumpkin puree
  • 1/2 teaspoon baking soda
  • 2 teaspoons pumpkin pie spice*

For the pumpkin spice frosting:

  • 7 tablespoons unsalted butter
  • 3 tablespoons buttermilk
  • 2 heaping cups powdered sugar
  • 1 teaspoon pumpkin pie spice


  1. Preheat the oven to 350 and spray a quarter sheet pan (9" x 13" x 1") with cooking spray.
  2. In a large bowl, whisk together the flour, sugar and salt.
  3. In a separate bowl, whisk together the melted butter, buttermilk, egg white, pumpkin, baking soda and pumpkin pie spice. Mix very well.
  4. Pour the pumpkin mixture into the bowl with the flour, and stir until everything is combined.
  5. Pour the batter into the prepared pan and bake for 16-18 minutes, or until a toothpick inserted comes out clean.
  6. While the cake cools, make the frosting: in a small sauce pan, melt the butter over medium heat. You can brown the butter if you like. Whisk in the buttermilk and powdered sugar. Add the pumpkin spice last, and whisk very well to combine.
  7. Pour the warm frosting over the cake, let rest for about 15 minutes (or longer) before slicing and serving.


*To make your own pumpkin pie spice, mix 1 tablespoon of ground cinnamon, 2 teaspoons ground ginger, 1 teaspoon ground nutmeg, 1/2 teaspoon allspice, 1/2 teaspoon cloves, and 1/2 teaspoon finely ground black pepper.
