Mix all of the rub ingredients in a small bowl.
Generously coat the ribs with the prepared rub, ensuring all sides are covered.
Place the ribs in the slow cooker, positioning the meaty side against the inner wall of the Crockpot.
Pour the BBQ sauce generously over the ribs, making sure to get sauce between the meat and the Crockpot wall for even flavor distribution.
Cover the slow cooker and set it to cook on LOW for 7 hours, allowing the ribs to tenderize and absorb the flavors.
Optional: For an added touch, periodically baste the ribs with the sauce juices during cooking. If desired, you can broil the ribs in the oven at 400-450 degrees for 5 minutes or use the broiler setting to caramelize the sauce for a delectable finish.
