Vanilla Buttercream Frosting (From Sprinkles Cupcakes)

My sister got this buttercream frosting off the box of a Sprinkles Cupcake mix, made famous by Oprah. My sister said this was amazing. Update: I have finally gotten around to making this myself. I will say, that I don't like my desserts overly sweet and. though this was very good, I think I would probably decrease the amount of sugar for my personal taste. I'm glad everyone else has liked it as-is, though. :)
