In a sauce pan bring to a boil the sugar, cocoa powder, butter and milk. Let boil for 1 to 2 minutes, stirring occasionally. While that's boiling - in a large bowl combine peanut butter, vanilla and oatmeal. After the sugar mixture has boiled add it into the oatmeal mixture and combine thoroughly. Mix in coconut last. Drop mixture by the spoonful onto wax paper and let cool.
Makes around 24 large cookies. You could easily get way more cookies by just making them a little bit smaller, mine tend to be on the large side.
Enjoy! (and don't blame me if you eat the whole batch by yourself in two days!)
