This frosting is the perfect compliment to "the best cinnamon rolls ever". Put it on right as you pull the rolls from the oven, they will soak up some of the sweetness and moisture from the frosting. We can never decide if they are best fresh from the oven or the next day after the frosting has had a chance to sit, either way they are delicious! This frosting is also great on cookies.
