Preheat smoker to 225 degrees Fahrenheit.

Remove the membrane from the ribs. Thoroughly coat in olive oil (the oil will act as a binder for the dry rub).

Prepare the dry rub: In a small dish, combine the sugar, paprika, salt, pepper, and garlic powder. Generously massage the dry rub onto the ribs.

Place in the smoker and cook until the internal temperature reaches 200 degrees Fahrenheit, about 10–11 hours depending on the smoker.

Set aside to rest for 30 minutes before slicing.
