1 stick butter (1/4 lb.)
1 cap (about 4 drops) vanilla
1 lb. (box) powdered sugar
Milk (enough to make the proper consistency for drizzling)

Add butter, vanilla and half of powdered sugar. Add milk and rest of sugar until icing is the correct consistency for pouring over cinnamon rolls in a thin stream. If not pourable, add a few drops more milk at a time; if too thin, add a few tablespoons of sugar at a time, stirring in until thick enough.
