Ingredients

Pumpkin Sheet Cake

  • 1 can 15 ounces pumpkin puree
  • 1 cup brown sugar
  • 1 cup granulated sugar
  • 2 teaspoon vanilla extract
  • 1 cup vegetable oil
  • 4 large eggs room temperature
  • 2 cups all-purpose flour
  • 2 teaspoon baking soda
  • 1 teaspoon ground cinnamon
  • ½ teaspoon ground ginger
  • ½ teaspoon freshly ground nutmeg
  • ½ teaspoon kosher salt

Cream Cheese Frosting

  • ½ cup 1 stick unsalted butter, room temperature
  • 8 oz 1 pack full fat cream cheese, room temperature
  • 1 teaspoon vanilla extract
  • 5 ½ cups powdered sugar
  • ¼ cup milk

Instructions

  • Preheat your oven to 350 degrees F (180 degrees C/160 degrees C fan-forced).
  • Grease a 15x10x1 inch baking pan (or 9x13 baking dish) with shortening or butter. Set aside.
  • In a large bowl whisk together the pumpkin puree, brown sugar, granulated sugar, vanilla extract, and oil until well combined. Beat in eggs one at a time until fully incorporated.
  • Combine the all-purpose flour, baking soda, cinnamon, ginger, nutmeg, and salt. Gradually add the dry ingredients to the pumpkin mixture, stirring together with a spatula until the dry ingredients are just combined with the wet ingredients.
  • Pour the pumpkin cake batter into the greased baking pan. Bake at 350° for 25-30 minutes (or 45-50 minutes for a 9x13 baking dish) or until a toothpick inserted in the center comes out clean.
  • Cool the sheet cake on a wire rack.

  • Cream Cheese Frosting
  • In a medium mixing bowl, beat the room temperature cream cheese with an electric hand mixer until smooth with little to no lumps left. Add butter and vanilla extract with an electric hand mixer until fluffy and smooth.
  • Gradually beat in powdered sugar until smooth. Add in splashes of milk until the frosting reaches desired spreading consistency.
  • Frost the cake generously and serve.

Notes

Storing Pumpkin Sheet cake

You've got to store your pumpkin cake in the fridge. It's got dairy on top of it: the cream cheese frosting. You gotta put that baby away in the fridge. Wrap her up with plastic wrap and she can last for up to 3 days in there.

Can I make it ahead of time?

Make the cake a day in advance, wrap it in plastic wrap. It can stay on the counter without the frosting. Make the frosting the day of; it'll stiffen up in the fridge and hard to spread across your cake if you make it too early.
