Using a 6 quart pan, heat, stir, and melt sugar, butter, milk, and cocoa together.

Once blended, bring sugar, butter, milk, and cocoa to a full boil.

Boil for one minute starting "the minute" when bubbles roll across the top of the mixture.

After boiling for one minute, quickly stir in vanilla, peanut butter and oats. Drop by spoonfuls onto waxed paper, parchment paper, or aluminum foil. Work quickly as they set up fast.
