Preheat your oven to 350°F (180°C).

Remove the tough membrane from the underside of the ribs and place them on a baking sheet lined with foil or parchment paper.

In a bowl, mix together garlic powder, onion powder, paprika, salt, pepper, cumin, and chili or Cayenne. Sprinkle the seasoning over the ribs and drizzle with oil. Rub the seasoning all over the ribs, covering both sides. Cover the tray with foil and bake for 2 hours.

In the last 5 minutes of baking, prepare the sauce by mixing together the ingredients.

Once the ribs are done baking, remove them from the oven and discard the foil. Spread the barbecue sauce mixture over the tops of the ribs.

Increase the oven temperature to 460°F (240°C). Return the ribs to the oven, uncovered, and bake for an additional 10 minutes.

Switch the oven settings to broil (or grill) on medium-high heat to lightly char and caramelize the edges of the ribs, about 3 minutes.

Let the ribs rest for 10 minutes before slicing to allow the juices to redistribute.

Serve and enjoy your delicious ribs!
