Surprisingly, cookies were not created intentionally. Some Dutch cooks were testing the oven temperature with small cakes. They called these koekje, which literally means 'little cake', and these turned into cookies later. They are now available in an innumerable variety, and some of their classifications include bar, drop, sandwich, filled, and molded cookies. And out of the drop cookies, oatmeal ones take care of our taste and health at the same time.
