Add all ingredients except for the BBQ sauce to your slow cooker. Cook on low 6-8 hours or high 4-6 hours or until the meat has pulled back 1" from the bone. Stir every hour or so.
The ribs will be falling apart, so remove them carefully to a foil-lined baking sheet.
Brush the ribs on all sides with the BBQ sauce.
Place under an oven broiler on high for 5 or so minutes until the sauce is set and the ribs start to get a little char along the edges. Flip the ribs once.
Serve immediately, cutting into single bone servings if desired.
