In large saucepan over medium to high heat combine sugar, milk, cocoa, salt, and butter and mix well. Bring to a boil and allow to boil for approx 1 minute to allow the sugar to melt completely. Remove from heat and stir in peanut butter and vanilla until smooth. Add oatmeal and mix well. If needed add another ½ cup of oatmeal to soak up any extra liquid. Allow mixture to sit 5-10 mins with an occasional stir to finish thickening up!
