A Dutch oven can bake such as bread bread, yes, but a very popular way to bake bread in a Dutch oven is in another oven or over charcoal where you can also apply heat on the lid with charcoals in order to "bake" the bread. Otherwise it is just a cast iron pot with heat only applied to the bottom from a burner.

Yeah, it's baking but tedious and somewhat of a dedicated art.
