in a stand mixer with paddle attachment, add butter and beat on high for 4 minutes, scraping

the bowl once light and fluffy

add 6 cups powdered sugar, milk, puree, and spices to mixer and mix on low speed for 30

seconds, then increase speed to high until frosting is smooth

add rest of powdered sugar if needed to get desired consistency

due to the puree making the frosting a little loose, I put my mixing bowl in the fridge to firm up prior to frosting the cupcakes.

once I frosted cupcakes, I sprinkled some pumpkin pie spice on top :) ENJOY!
