Preheat oven to 350 degrees. Spread a thin layer of butter in a 9" x 13" baking pan to prevent sticking.
In a small mixing bowl whisk together melted butter, cinnamon honeyand salt.
Place sweet potatoes/yams in baking dish, pour cinnamon honeyand butter mixture over top and toss well to evenly coat.
Spread into an even layer (they will overlap) and bake in preheated oven until soft, tossing every 15 - 20 minutes. Bake for 50 - 55 min total.
There will be some cinnamon honeyand Butter mixture left at the bottom of the pan after baking. Use this mixture to pour over the Sweet Potatoes/Yams and toss to make sure they are evenly coated.
