This homemade pumpkin buttercream frosting takes just 5 minutes to prep and has all of the flavors of a pumpkin pie! Real pumpkin and pumpkin pie spice are used to make this fool-proof frosting that tastes amazing on my easy pumpkin cake, moist pumpkin cupcakes, and so many other fall treats.
In the bowl of an electric stand mixer using the paddle attachment, beat the butter on high speed until smooth and creamy (about 1-2 minutes).
Add the powdered sugar, pumpkin puree, vanilla extract, pumpkin pie spice, and cinnamon and mix on low speed until combined (about 30 seconds).
Then increase the speed to high and beat for another 1-2 minutes (frosting should be light and creamy).
Use it to frost your favorite cupcakes and cake recipes!
Notes
Room Temperature: The butter needs to be at room temperature in order to create the perfect consistency of buttercream frosting. If you start with cold butter, you'll have a difficult time getting the frosting to come together.Pumpkin: Use pumpkin puree for the best pumpkin flavor.Baked Desserts: Make sure any dessert you use this frosting on is completely cooled before frosting. If not, the frosting will melt right off.Powdered Sugar: Do not reduce the amount of powdered sugar this recipe calls for. It's what helps to stabilize the frosting and gives it that smooth and creamy texture without being wet and runny.
