In a medium sized pot on medium heat, stir together the sugar,cocoa powder, milk, butter and salt. Stir until mixture just starts to boil,reduce heat to low and stir 2-4 minutes until mixture looks well blended, but not dry. If mixture looks like its getting too dry, remove from heat or dribble in small bits of milk. Turn off burner, stir in vanilla and keep pot on the burner while adding oats and coconut all at once. By keeping the pot on the warm burner keeps the mixture from cooling off too quickly while mixing in oats and coconut. Stir really well, then with 2 spoons drop onto wax paper or parchment paper. Mixture will cool really quickly, so don’t dawdle.
