This Pumpkin Cake with Spice Cake Mix is a quick and easy fall dessert! It's packed full of fall spices that we all love and topped with a cream cheese frosting.
Preheat the oven to 350 degrees F. Grease a 9x13 baking pan with nonstick baking spray.
In a large bowl, add in the spice cake mix, eggs, pumpkin purée, evaporated milk, vegetable oil, brown sugar, pumpkin pie spice, and vanilla extract. Beat using a hand mixer on medium speed until the batter is smooth and the eggs are incorporated.
Pour the batter into the prepared baking pan and spread out.
Place in the preheated oven and bake for 32 - 37 minutes or until a toothpick inserted into the center of the cake comes out clean or with moist crumbs.
Remove from the oven and let cool completely.
Frosting
In a large mixing bowl, add in the cream cheese and butter. Beat using a hand mixer on medium speed until smooth.
Add in the powdered sugar and vanilla extract. Beat on low until the powdered sugar is mostly worked into the frosting and then turn the mixer to medium and beat until the frosting is whipped, about 30 seconds to 1 minute.
Spread the frosting on top of the cooled cake.
Using a fine mesh strainer, add the cinnamon into it and dust the top of the frosting with cinnamon.
Cover with plastic wrap and store in the refrigerator up to 5 days.
