In a small bowl, prepare the rub by combining 1 tablespoon brown sugar, 2 teaspoons smoked paprika, 1 teaspoon kosher salt, 1 teaspoon onion powder, 1 teaspoon garlic powder, and ½ teaspoon black pepper together.
Pat the chicken drumsticks dry with a paper towel then liberally rub the spice rub over the chicken, coating to cover.
Grease the slow cooker insert with cooking spray. Place the chicken legs into the slow cooker. Cover and cook on high for 2 hours or on low for 4-5 hours.
Once the chicken legs have reached an internal temperature of 175-190℉, remove them from the slow cooker and place them onto a sheet pan or broiler pan. Brush the chicken legs with barbecue sauce and broil until crispy, about 2-3 minutes per side.
Serve with extra BBQ sauce on the side.

Notes
Chicken Skin: For juicy, flavorful chicken drumsticks, cook with the skin on and discard after cooking if you don't want to eat the skin. Alternatively, you can peel off the skin before rubbing with the spice blend. The chicken will be delicious, but not as juicy. Brown Sugar: This is completely optional, but adds a nice balance to the rub. All-Clad Slow Cookers: These models can cook a bit faster, so begin checking the temperature of the chicken 30 minutes prior to what the recipe states. Determining Cook Time: The best way to ensure your chicken is fully cooked, but not overcooked is to use a digital thermometer. Once the center of a chicken leg reaches between 165°F the drumsticks are safe to eat, but taking them to closer to 175-190°F ensures they are super tender.Storage: Store leftover chicken legs in an airtight container in the refrigerator for 3 days. Reheat by broiling under a broiler for 2-3 minutes per side.
