Make the dry rub mixture by combining all of the ingredients but the ribs in a small bowl. Set aside.
Prepare a large baking sheet by covering the bottom with foil. Add a wire rack on top and spray with non-stick cooking spray. Set aside.
Remove the membrane from the back of both ribs if it was not already removed. Use a paper towel to help make removel easier. Discard membrane.
Coat both sides of the ribs evenly in the dry rub mixture. Pat the seasoning into the meat to help it stick. Save any unused dry rub in a closed container.
Place ribs on prepared wire rack. Cook in preheated oven for four hours or until a fork pierces easily through the middle of the rib meat. If desired, add barbeque sauce and broil for a couple of minutes before serving.
Notes
*If you prefer your ribs to be a little spicier, add 1 teaspoon of cayenne pepper to the dry rub mix.
