Preheat oven to 400 degrees F. Line a baking sheet with sides with parchment paper. Set aside.
Cut ribs into 6 sections then rinse and pat dry.
In a medium bowl, whisk together Spice Rub ingredients. Rub evenly all over the meat then place ribs on prepared baking sheet. Bake ribs for 15 minutes ON EACH SIDE (30 minutes total) to sear meat.
Meanwhile, whisk together all of the Honey Buffalo Sauce ingredients EXCEPT the cornstarch. Remove and reserve 1 cup Sauce to brush on cooked ribs. Whisk cornstarch into remaining Sauce (not the reserved sauce).
Spray slow cooker with nonstick cooking spray then add a thin layer of sauce, followed by ribs. Layer sauce then ribs until complete, tossing to coat as needed to ensure ribs are evenly coated in sauce.
Cover and cook on HIGH for 4-5 hours or on LOW for 7-9 hours OR cook until ribs are fall apart tender. Rotate ribs once during cooking so they cook evenly. Cooking time may vary between slow cookers.
When ribs are tender, remove from slow cooker and brush with Reserved Honey Buffalo Sauce. Serve the rest of the Sauce a dip if desired.
