Mama said “close,” and I’m keeping that. My butter was too warm, my sugar was too heavy, and I’m already planning next year’s pie with both of those corrections locked in — but while I work back up to that scratch crust, this Pumpkin Pie Sheet Cake is where I’m parking those same flavors: the cinnamon, the nutmeg, the warm custard sweetness that lives in every great sweet potato pie Mama ever made. It’s forgiving in all the ways a first pie isn’t, and it’s the kind of dessert Aiden and Zaria can help with, which means it already has a place at our table.
Pumpkin Pie Sheet Cake
Prep Time: 15 min | Cook Time: 25 min | Total Time: 40 min (plus cooling) | Servings: 24
Ingredients
- 1 can (15 oz) pumpkin puree
- 4 large eggs
- 1 cup granulated sugar
- 1/2 cup packed light brown sugar
- 1/2 cup vegetable oil
- 2 tsp vanilla extract
- 2 cups all-purpose flour
- 2 tsp baking powder
- 1 tsp baking soda
- 1/2 tsp salt
- 2 tsp ground cinnamon
- 1/2 tsp ground nutmeg
- 1/4 tsp ground ginger
- 1/4 tsp ground cloves
- Cream Cheese Frosting:
- 8 oz cream cheese, softened to room temperature
- 1/4 cup unsalted butter, softened to room temperature
- 2 cups powdered sugar, sifted
- 1 tsp vanilla extract
- Pinch of cinnamon, for dusting (optional)
Instructions
- Preheat and prep. Preheat your oven to 350°F. Grease a 13x18-inch rimmed sheet pan (half-sheet pan) with butter or non-stick spray and lightly flour it, or line it with parchment paper.
- Mix the wet ingredients. In a large bowl, whisk together the pumpkin puree, eggs, granulated sugar, brown sugar, oil, and vanilla until smooth and fully combined.
- Combine the dry ingredients. In a separate bowl, whisk together the flour, baking powder, baking soda, salt, cinnamon, nutmeg, ginger, and cloves.
- Bring it together. Add the dry ingredients to the wet ingredients and stir until just combined — do not overmix. The batter will be thick.
- Spread and bake. Pour the batter onto the prepared sheet pan and spread it evenly to the edges with a spatula. Bake for 22–26 minutes, until a toothpick inserted in the center comes out clean and the edges are just pulling away from the pan.
- Cool completely. Set the pan on a wire rack and let the cake cool completely before frosting. Do not rush this step — frosting a warm cake will cause the cream cheese frosting to melt and slide.
- Make the frosting. Beat the softened cream cheese and butter together with a hand mixer or stand mixer on medium speed until smooth and fluffy, about 2 minutes. Add the powdered sugar one cup at a time, beating on low to incorporate, then add the vanilla and beat on medium until creamy and spreadable.
- Frost and finish. Spread the cream cheese frosting evenly over the cooled cake. Dust lightly with cinnamon if desired. Slice into squares and serve.
