Pumpkin Sheet Cake

This is a simple recipe for a moist spiced pumpkin sheet cake with a homemade cheese cheese frosting.

Once upon a time there was a recipe blog that I loved called Tammy’s Recipes. It was super simple and for most of the recipes there weren’t even any pictures. At the bottom, Tammy reviewed each of her own recipes and usually gave them a 10/ 10. Pretty reasonable. Anyway, the best recipe on that blog was this pumpkin sheet cake.

I made it every single year without fail with only a few tiny tweaks. One year I went to go look it up, and the blog was gone. There was a Facebook page called Cooking with Tammy, but that something else. No more Tammy’s Recipes.

Luckily, I had printed it out and the recipe was somewhere in the depths of my recipe binder. The print date on it is 2008. I am republishing it here so that I have it forever and so that you can make it too. Please print it. You never know when I’ll disappear.

If Tammy is out there, I hope she’s okay, and I hope she doesn’t mind.

This recipe is very simple and is served right out of the pan… a cozy and unpretentious dessert. If you want to get fancy, it could certainly be baked in 8 inch cake pans and layered. You would definitely want to double the cream cheese frosting, as there is none left over.

Yes there is a lot of sugar, oil, and eggs in this cake. That is what makes it moist. I have tweaked the leavening and spices from the original recipe and I think it is better this way.

Baking pumpkin sheet cake, step by step

Make sure you fully combine the eggs, oil, sugar, and pumpkin before adding the dry ingredients. Once you add the flour, you want to mix as little as possible.

Use a jelly roll pan for baking. You want a shallow cake and the jelly rolls pan is the perfect thickness. When you remove the cake from the oven, it might look a little uneven. Just let it cool and it will even out over the next few minutes.

Make sure all your icing ingredients are at room temperature before mixing to avoid lumps.

All that’s left to do is frost and serve!

Caramel Apple Cobbler is about a thousand times easier than apple pie but just as delicious.

Try my soft molasses cookies, which can perfect any time from fall into Christmas.

Apple Bundt cake with cider glaze is a bit fancier and super delicious.

  1. I am so ready for cooler weather and the pumpkin recipes of fall! Bring it on. I set up a new fire pit off my patio Sunday while it was pushing 100 degrees here in Charlotte, NC. But, still, I know the cool breezes are on their way.

    That does look super tasty!
