Ingredients

Cake

  • 1 cup unsalted butter, melted
  • 1 cup milk, 2%
  • 1 cup pumpkin puree, not pumpkin pie filling
  • 2 cups granulated sugar
  • 3 large eggs
  • 1 teaspoon vanilla extract
  • 2 cups all-purpose flour
  • 2 teaspoons baking soda
  • 1 teaspoon ground cinnamon
  • 2 teaspoons pumpkin pie spice
  • ½ teaspoon salt

Frosting

  • ½ cup unsalted butter, softened
  • 250 grams cream cheese
  • ⅓ cup heavy cream, 33%
  • 1 teaspoon vanilla extract
  • 1 teaspoon ground cinnamon
  • 4 cups powdered sugar

Instructions

  • Preheat the oven to 350°F.
  • Spray a large sheet pan (13x18x1 inches) with non-stick cooking spray. Set aside.
  • In a large bowl, whisk together melted butter, milk, pureed pumpkin, sugar, eggs, and vanilla. Whisk until well combined.
  • In a separate bowl stir together flour, baking soda, cinnamon, pumpkin pie spice, and salt.
  • Place dry ingredients into wet ingredients and stir just until mixed.
  • Pour into the sheet pan. Bake for 20 minutes or until a toothpick inserted in the center comes out clean.
  • Let the cake cool for 15 minutes before icing.
  • To make the frosting, beat together the butter and cream cheese on high speed until smooth, about 3 minutes.
  • Add in heavy cream, vanilla, and ground cinnamon and beat on high speed for 2 minutes.
  • Add in powdered sugar gradually. Beat on high speed for 3 minutes, scraping down sides of bowl frequently.
  • Spread icing evenly over the cake.

Notes

  • Watch out when you are at the grocery store that you buy pure pumpkin purée and not canned pumpkin pie filling.
  • Using a different sized sheet pan will result in changes to the thickness of the cake and may need cooking time adjusted.
  • Make sure the cream cheese is at room temperature so that you don't have lumps in your cinnamon cream cheese frosting.
