Cinnamon is a spice that is a thin layer peeled from the inner bark of the cinnamon tree. It has a sweet, aromatic flavor and is commonly used in baking or cooking desserts, such as cinnamon rolls.

Cinnamon bark, on the other hand, is a layer of the bark of the cinnamon tree that is usually used as a seasoning for soups or stews. Cinnamon bark is usually tough and woody, and requires longer cooking and braising to soften and absorb the flavor of the meat.

So while cinnamon and cinnamon bark come from the same tree, they have different uses and different flavors and aromas. Cinnamon is generally used in baking or cooking desserts, while cinnamon is used as a seasoning for stews or soups.
