Prepare brownie mix according to box directions by adding the water, oil, and eggs (or what is directed on back of box) and cool completely.
Then adjust oven to 400 degrees F and place coconut on baking pan. Cook for 2-3 minutes. Stir coconut and cook for another 2-3 minutes until toasted. Watch closely so it doesn't burn.
Unwrap the caramels and in a large microwaveable bowl, add unwrapped caramels, salt, and milk and cook on high for 3 minutes, or until caramels are melted and smooth. (Stirring about every 45-60 seconds).
Add coconut to caramel and mix together. Spread over cooled brownies.
Refrigerate 4-5 hours or overnight.
Remove at least 1 hour from the fridge before cutting.
Cut into bars and drizzle with melted semi-sweet chocolate.
