Welcome Fall and cooler weather this amazing homemade Pumpkin Spice Cake. A classic pumpkin cake that is so soft and moist thanks to the oil and pure pumpkin, baked in a 9x13 pan, with lots of warm pumpkin spice flavors, and then it's topped with a simple cream cheese frosting.
Preheat the oven to 350° F. Spray a 9x13 baking pan with cooking spray, set aside.
In a large mixing bowl, the flour, brown sugar, granulated sugar, pumpkin pie spice, baking powder, baking soda, and salt. Stir with a wire whisk. Set aside.
In a separate smaller mixing bowl, add the pure pumpkin, oil, beaten eggs, whole milk, and vanilla extract. Whisk together with a wire whisk, or you can use hand mixer if wanted, until ingredients are thoroughly mixed. * For beaten eggs : Crack the eggs into a separate bowl and use a fork to stir them up, then add them into the batter.
Add the wet ingredients into the larger bowl of dry ingredients. Mix until everything is combined and no flour streaks or spots remain in the batter.
Pour the pumpkin cake batter into the prepared pan. Bake for 25-35 minutes or until a toothpick inserted into the middle comes out clean.* The edges will turn golden brown and pull away from the sides of the pan, and the cake will be puffy in the middle, and a toothpick inserted in should come out clean or with crumbs, not wet batter. * Mine takes almost exactly 30 minutes to bake.
Remove the cake from the oven and allow it to cool completely before frosting.Once cooled, you can either frost it and serve. Or you can cover the cooled cake with a lid or tin foil and refrigerate it until ready to serve. The cake can also stay out at room temperature, unfrosted, if needed.
Place the softened cream cheese and butter into a mixing bowl, or use a stand mixer, and beat on low speed, increasing speed as needed, until it's smooth and creamy.
