Whats a good recipe for brownies?

im craveing some brownies but i dont want little debbie ones or anything. i wanna make some really good ones at home but i usualloy just buy a box of them and bake them but i wanna make some VERY good ones. with like special stuff on there. for example: hersheys bars in the middle or like Melted marshmellows on the top or something like that. im not much of a cooker but i know how to follow the directions though.
