Step 1

Preheat oven to 350F (176C) and prepare a baking pan (we used a 9" x 13" rectangular pan) by greasing the sides and lining the pan with parchment paper.

Step 2

Mix together your wet ingredients (pumpkin puree, vegetable oil, eggs, vanilla extract, brown sugar, and granulated sugar) in a mixing bowl. Whisk well to combine.

Step 3

In a separate bowl, mix together your dry ingredients (flour, baking powder, baking soda, pumpkin pie spice, cinnamon, and salt). Whisk well to combine.

Step 4

Combine the wet and dry ingredients by whisking together until the mixture is just hydrated - don't overmix!

Step 5

Transfer the batter to the prepared baking dish. Spread into an even layer.

Step 6

Bake the cake for 30-40 minutes until a cake tester inserted in the middle of the cake comes out clean.

Step 7

Let the cake cool completely. In the meantime, make cream cheese frosting by combining softened butter and cream cheese in the bowl of a stand mixer (you can also whisk it together by hand or using a handheld mixer!)

Step 8

Once the cream cheese and butter are combined, add in powdered sugar, orange zest, and a pinch of salt and whisk together until light and fluffy.

Step 9

When the cake has cooled, spread cream cheese frosting across the top. Add any additional decoration, such as candied orange slices, orange sprinkles, or orange zest. Slice and enjoy!
