01 - Place chicken breasts in the bottom of the slow cooker in a single, even layer.
02 - In a medium bowl, whisk together the barbecue sauce, honey, Worcestershire sauce, garlic powder, onion powder, smoked paprika, and black pepper until fully combined.
03 - Pour the sauce mixture evenly over the chicken, ensuring all pieces are covered.
04 - Cover and cook on low for 4-5 hours or on high for 2-3 hours, until the chicken is tender and reaches an internal temperature of 165°F.
