Mix the brown sugar, paprika, chili powder, garlic powder, salt, and pepper and rub it all over the brisket.
Slice the onion into the slow cooker, set the brisket on top fat side up, and pour the broth around it.
Cover and cook on LOW for 8-9 hours until very tender.
Rest the brisket for 10 minutes, then slice it thin across the grain.
Skim the fat off the juices, stir 1/2 cup of the juices into the barbecue sauce, warm it, and spoon over the sliced beef. Serve with buns or coleslaw.
