Just like the name says, this is the easiest peanut butter icing you could ever make--and, in my opinion, the tastiest!
2 C. powdered sugar 1/2 stick margarine 1/3 C. milk 1/2 C. peanut butter
Melt margarine and put in mixing bowl. Mix on low or medium speed while you add some of the sugar and then some milk. Keep adding sugar then milk until you get the desired consistency. Add peanut butter. Add more sugar or milk if desired to get back to the desired consistency. These measures are approximate. We usually don't measure any of it exactly. We just keep adding one or the other until we get a spreadable consistency. You really can't mess it up.
