Pat the baby back ribs dry with paper towels and remove the thin membrane (silver skin) from the back of the rack.
In a small bowl, combine the smoked paprika, garlic powder, onion powder, sea salt, and black pepper.
Rub the spice blend thoroughly onto both sides of the ribs, pressing it into the meat.
Lightly grease the bottom of the slow cooker with avocado oil and place the ribs inside, curling them to fit if necessary.
Cover and cook on low for 7 to 8 hours, or on high for 4 hours, until the meat is tender and pulling away from the bone.
Preheat your oven broiler to high and line a baking sheet with parchment paper.
Carefully transfer the cooked ribs to the baking sheet and brush the top generously with the sugar-free BBQ sauce.
Broil the ribs for 3 to 5 minutes until the sauce is bubbly and caramelized.
While the ribs broil, whisk together the apple cider vinegar, Dijon mustard, and raw honey in a medium bowl.
Toss the shredded cabbage and carrots into the dressing until well coated.
Serve the sticky BBQ ribs alongside the fresh vinegar slaw.
