In a small bowl, combine brown sugar, smoked paprika, garlic powder, onion powder, salt, pepper, and cayenne pepper.
Lightly spray the insert of your slow cooker with cooking spray, pour in the pineapple juice, then add the chicken in a single layer. Sprinkle half the seasoning blend over the chicken, flip, and sprinkle the opposite side of the chicken with the remaining seasoning.
Place the lid on the crockpot and cook on LOW for 5-6 hours or HIGH for 3 hours. The chicken breasts are fully cooked when they reach an internal temperature of 165°F (73℃) and easily shred.
Once the chicken is fully cooked and tender, remove it to a clean cutting board or large mixing bowl and shred it with two forks.
Return the shredded chicken back to the slow cooker, add ½ cup of BBQ sauce, and stir to combine, adding more sauce as needed, desired to ensure the chicken is well coated in the BBQ sauce.
Return the lid to the slow cooker and cook on HIGH for 10-15 minutes to warm through.
Serve as desired with additional BBQ sauce.

Notes
Swap Chicken Breasts for Thighs: Use boneless, skinless chicken thighs trimmed of fat and grizzle and slow cook until the thighs reach 185°F for tender results. Cayenne Pepper: Omit or decrease to control spice level.BBQ Sauce: Any variety of BBQ sauce works here. Use what you love as the flavor make a huge impact to the overall taste of the pulled chicken. Pineapple Juice: Use canned juice for the best flavor. Drained from a can of pineapple in 100% juice works well. Storage: Store in airtight container for up to 4 days in the fridge or up to 3 months in a freezer-safe container. Defrost in the fridge if needed and reheat as desired.
