  6. Evenly spread the batter into the sheet pan and back for twenty-five to thirty minutes and let it cool on a wire rack for around two hours. 
  7. Next, make the icing by melting the butter in a medium saucepan, being careful not to burn the butter.

Recipe Variations and Substitutions:

  • Gluten-Free: Substitute gluten-free all-purpose flour for the regular flour to make the cake gluten-free.
  • Vegan: To make a vegan pumpkin sheet cake, replace the eggs with flax or chia seed eggs (1 tablespoon ground flaxseed or chia seeds mixed with 3 tablespoons of water per egg). Also, use dairy-free butter or margarine, and replace the milk in the icing with plant-based milk (e.g., almond, soy, or oat). 
  • Sweeteners: Experiment with alternative sweeteners such as brown rice syrup, coconut sugar, or maple sugar instead of granulated sugar.
  • Cream Cheese Frosting: Instead of the brown sugar icing, try a classic cream cheese frosting. Beat together cream cheese, butter, powdered sugar, and vanilla until creamy and smooth.
  • Garnishes: Customize the cake by adding chopped toasted pumpkin seeds, chocolate chips, or caramel drizzle on top of the icing.

Serving and Storing Tips:


  • Serve Pumpkin sheet cake at room temperature or chilled.
  • Cut it into squares and serve it on its own or with a scoop of ice cream. 


  • Store the pumpkin sheet cake recipe in an airtight container for up to 3 days at room temperature.

Pumpkin Sheet Cake Recipe FAQs

What’s the difference between sheet cake and regular cake?

The main difference is the size of the pan used to make the cake. A sheet cake is made in a sheet cake pan, which is large and shallow. It is an ideal dessert for feeding a crowd. A regular cake is typically made in 8 or 9-inch rounds or a 9×13-inch pan, resulting in a thicker and smaller cake. 

How to bake a half-sheet cake?

This pumpkin sheet cake will take approximately twenty-five to thirty minutes to bake at 350 degrees F. Each oven bakes slightly differently, so keep an eye on it and remove the cake once a toothpick comes out clean. 

How many people should a half-sheet cake feed?

You can cut twenty-four slices of this pumpkin sheet cake. However, you could cut them smaller and be able to serve even more.
