Place the sweet potatoes in a Dutch oven and cover with water. Cover and bring to a boil; boil gently 30-45 minutes or until potatoes can be easily pierced with the tip of a sharp knife.
While potatoes cool, preheat oven to 375°. When sweet potatoes are cool enough to handle, peel potatoes and cut into wedges. Place in an ungreased 11x7-in. baking dish. Sprinkle with brown sugar and cinnamon. Dot with butter; drizzle with corn syrup.
Bake, uncovered, 15-20 minutes or until bubbly, basting with sauce occasionally.
