In a saucepan, boil (2 1/2 min.) butter, sugar, milk, & cocoa. Remove from heat. Add vanilla, oats, and cocoanut (Stir it in quickly!) Drop on wax paper to harden- appx. 1/2 hour.
**note** Try Not to eat all of the batter before it cools. The result is a tummy ache that disturbs the full enjoyment of the finished product (at least for an hour.) And you would have to make more batter!!!!
