This Pumpkin Sheet Cake with Cream Cheese Frosting is an easy and delicious way to enjoy the flavours of the Fall season.

I love sheet cakes. No layers to fiddle with. Just mix, bake and spread the frosting over-top, all without having to remove the cake from the pan (unless you want to, of course). Garnish with some nuts and you’re good to go. As this one is baked large and a little thinner, it’s a great snacking cake or a lovely addition to a holiday dessert table.

Ingredients and Substitutions

Pumpkin Puree – this is the canned, pure pumpkin puree, which is not the same as pumpkin pie filling.

Vegetable Oil – I find vegetable oil tends to perform best in baking, but any neutral-tasting oil, such as canola or sunflower will work here as well.

Walnuts – If you don’t like walnuts, you can replace with pecans or omit nuts completely. I like to scatter the nuts in the pattern down the middle, leaving a few areas uncovered. That way there’s alway a nut-free piece for those that don’t like the nuts.

Recipe Tips

This cake calls for a 15 x 10-inch baking pan (aka jelly roll pan). You’ll want one with sides at least 1 inch high. I happened to have this size cake pan, with 2-inch high sides. If you don’t you could bake in a 9×13. Do note that I haven’t tried this, but my math tells me that a 9 x 13 pan would only take about 3/4 of the batter. So you’d definitely want to hold some of the batter back. A 9×13 cake will be thicker though, for sure, so baking time will be longer. Test in regular intervals until a tester comes out clean in the centre.

If you make this as a 15×10 sheet cake, there is “just enough” for a thin layer of cream cheese frosting. As such, you’ll want to spread carefully to avoid pulling up crumbs. My strategy is to place 3 dollops in the line down the centre of the cake and to spread each out to the edges.

I found the frosting to cake ratio really nice as is, as this cake is thinner than some, but if you really, really love the icing part and just want more, go ahead and double the frosting for a thicker layer.

Use the tip of an offset spatula to create a ridged design to your icing. Simply drag it lightly down the cake in lines, leaving a little space in between for the ridges.

5 stars from 9 ratings
Prep Time: 20 minutes
Cook Time: 30 minutes
Total Time: 50 minutes
Yield: 24 servings


For the cake:

  • 4 large eggs
  • 1 2/3 cup white sugar
  • 1 cup vegetable oil, or canola or other neutral tasting cooking oil
  • 2 cups pumpkin puree, not pie filling
  • 2 cups all purpose flour
  • 2 teaspoons cinnamon
  • 1 teaspoon salt
  • 1 teaspoon baking soda
  • 2 teaspoon baking powder

For the frosting:

  • 4 oz cream cheese, full fat, at room temperature (1/2 standard block)
  • 1/2 cup salted butter, at room temperature
  • 1 teaspoon vanilla
  • 2 cups icing/confectioners' sugar

For garnish:

  • 1/3 cup chopped walnuts, optional


  • Preheat oven to 350F.(regular bake setting/not fan-assisted). You will need a 15 x 10-inch baking pan with sides at least 1-inch high. If you want to remove your cake from the pan at all, line the bottom with parchment, leaving an overhang over the sides to use as handles to lift it out.
  • In a large bowl with an electric mixer or the bowl of a stand mixer fitted with a paddle attachment, beat together the eggs, sugar, oil and pumpkin until light and fluffy.
  • In a medium bowl, whisk together well the flour, cinnamon, salt, baking soda and baking powder. Add to the pumpkin mixture and mix until thoroughly combined.
  • Spread batter into an ungreased 15 x 10-inch baking pan with sides at least 1 inch high.
  • Bake in preheated oven for 25-30 minutes, or until a tester inserted in the middle comes out clean.
  • Remove from oven and allow to cool completely in the pan before frosting.
  • Once cooled, prepare the frosting by beating together the cream cheese and butter until light and fluffy. Add the vanilla and mix in. Add the icing sugar a bit at a time, beating until the frosting is smooth.
