Cinnamon Roll Icing (Just like Pillsbury): • 1/2 stick butter (4 Tbls.) • ¼ tsp. vanilla • .5 lb. (1/2 box) powdered sugar • Milk (enough to make the proper consistency for drizzling) -- Mix butter, vanilla and half of powdered sugar. Add milk and rest of sugar until icing is the correct consistency for pouring over cinnamon. Thumbs up.
