Oat bar

An oat bar is a convenient, baked snack bar primarily made from rolled oats, often bound together with sweeteners like honey or maple syrup and fats like butter or oil. It frequently includes add-ins such as nuts, seeds, dried fruits, or chocolate chips for texture and flavor. While its exact origins are tied to the rise of packaged health foods in the 20th century, it's now a globally popular snack.
