Make ribs in any slow cooker by placing the ribs in the slow cooker, adding half of a 12-ounce can of cola and cooking on low for seven hours. Drain the liquid, cover the ribs with a bottle of barbecue sauce and cook on high for another hour.
A more-involved recipe for cooking baby back ribs in a slow cooker offered by Better Crocker starts by mixing together 1 1/3 cups ketchup, 3/4 cup chili sauce, 2/3 cup brown sugar, 1/4 cup cider vinegar, 1 tablespoon liquid smoke, 2 tablespoons lemon juice and 3 tablespoons each Worcestershire sauce and Dijon mustard. Set this sauce aside and prepare the ribs.
Lightly salt and pepper the ribs with 3/4 teaspoon of salt and 1/4 teaspoon of pepper. Place the ribs in the slow cooker and cover with 1 1/2 cups of the prepared sauce. Refrigerate the remaining sauce. Cook the ribs on low for six to seven hours or high for three to four hours.
When the ribs are almost tender, remove them from the slow cooker and drain the cooking liquid. Return the ribs to the slow cooker and cover with the reserved sauce. Cook on high for an additional hour or until the pork is very tender.
