Add the chicken, barbecue sauce, and seasonings to a crockpot. Cook on low for 6–8 hours or high for 3–4 hours, then shred.
Bake the sweet potatoes at 400°F for 50–60 minutes until tender.
Slice open the sweet potatoes, mash lightly with a pinch of cinnamon, then fill with the BBQ chicken and cheddar cheese.
Bake for 5–10 minutes at 350°F until the cheese is melted, then top with green onions.
