Wash and dry sweet potatoes and pierce the skins with a fork in several places.
Drizzle with olive oil, and rub all over the skin of the sweet potatoes. Season them on all sides with salt and black pepper.
Place the sweet potatoes on the smoker, and smoke for 2 hours, or until the potatoes can be pierced with a fork. Aim for your potatoes to be between 205-215° F. A perfectly cooked sweet potato will have an internal temperature of 210° F
Remove the sweet potatoes from the smoker and allow to rest for 5-10 minutes.
Cut them open with a knife and fluff the insides. Top with your choice of toppings.
