My family LOVES brownies, but of course everyone wants something different. In the past I was crazy enough to make a pan of brownies for each. Some wanted mint with nuts, some wanted Heath chips, some wanted peanut butter. I tried to think of a way to only make the one tray, but provide them with their own favorites. This is my solution and has been a huge success at our house. The foundation is a boxed brownie mix with the extras on top. Very easy, very good. Enjoy.
