My mom has the best mocha butter-cream frosting recipe ever. I took that and switched it up a bit for fall. With the clever use of pumpkin pie spice, and my own crazy ingenuity, I have the perfect frosting for Autumn cupcakes/brownies/cookies/cakes.
To start out, put 1 stick of softened butter and 1 stick of softened margarine into a bowl. Add a 2 lb bag of powdered sugar and mix with a hand mixer. Once its all mixed up, add a couple shakes of pumpkin pie spice, a capful of vanilla, a shake of cinnamon and a shake of allspice. Mix it with a spoon this time, and its done! Put on everything!
