Mix sugar and cocoa in pan. Then add milk. Stir well. Place on stove on boiling heat. Immediately add butter.
Bring to boil, stir in butter. Once it reaches a boil, set timer for 3 minutes! ( this is very important!!!)
After 3 minutes is up, REMOVE from heat! Add vanilla and peanut butter.
Once peanut butter is mixed in well, add quick oats. Mix quick and pour into NON-OILED dish. Spread quickly. Wait for it to harden. We eat ours after about 15 minutes because we like it warm, but wait about an hour for total hardening.
