Sticky Oven Barbecue Ribs

1. Preheat your oven to 300°F (150°C).
2. Grab a bowl and stir together the brown sugar, smoked paprika, garlic powder, onion powder, salt, black pepper, and cayenne pepper.
3. Rub this sweet and smoky spice blend generously over both sides of the ribs.
4. Lay the ribs, meat side up, on a foil-lined baking sheet.
5. Cover the ribs tightly with another sheet of foil. Slide them in the oven and let them bake for 2½ to 3 hours, until tender.
6. Carefully peel off the foil. Brush the ribs all over with the barbecue sauce mixed with apple cider vinegar.
7. Crank the oven up to broil. Pop the ribs back in for 10 to 15 minutes, watching closely so they get deliciously caramelized and sticky but not burnt.
8. Let your ribs rest for a few minutes, then slice and serve. Enjoy every messy, finger-licking bite!
