Combine the butter, sugar, and milk in a saucepan and bring to a boil over medium high to high heat (enough to bring the syrup to a rapid boil). Stir frequently to prevent burning or boiling over!
Once the syrup is at a full rolling boil, stir and cook for 1 minute then remove from heat.
Add the vanilla and cocoa, stir until the syrup is smooth. Add the quick oats and stir until evenly coated with the syrup.
Drop tablespoon sized portions onto waxed paper, use the back of a spoon to make cookie shaped (rather than a no bake cookie mound) if desired. Allow to set up for one hour.
