Begin by spraying the bottom of a 6-quart slow cooker with non-stick spray to ensure easy cleanup later on. Lay out your chicken breasts in an even layer at the bottom of the cooker.
In a small bowl, combine cayenne pepper, smoked paprika, and garlic salt to create a flavorful seasoning mix that will enhance your chicken.
Generously sprinkle your seasoning mixture over the chicken breasts, followed by an even distribution of brown sugar on top for added sweetness.
Drizzle honey all over your seasoned chicken, allowing it to seep into every crevice, then place chunks of butter on top to enrich the sauce.
Pour in vinegar before covering your slow cooker, setting it to cook on LOW for 4 hours or HIGH for 2 hours until the chicken is tender enough to shred easily.
Once cooked, use two forks to shred your chicken directly in the slow cooker, mixing it with all those beautiful sauces before serving it on soft buns topped with crunchy pickles.
