Boil the ravioli. In a seperate sauce pan combine the butter and brown sugar on medium heat til they dissolve together, then simmer until the sauce thickens (it will thin out when you stir in the ravioli).
Remove from heat and add the parmesan and pine nuts. Drain the ravioli and gently stir it in with the sauce.
Place ravioli on individual plates and top with additional parmesan cheese and grated dark chocolate. (The dark chocolate really brings out an amazing flavor to the dish, don't skip this part!)
