Once upon a time, in my Roy Rogers lunch box, there was just one kind of delectable Oreo. Nowadays, have you seen how grocery stores devote a full aisle to cookies? I couldn't believe how many different flavors of the same cookies there are! Double stuff, reduced fat, different shapes and yummy cream fillings!

Over the Fourth of July weekend, we celebrated not only our nation's independence, but National Cookie Day, as well. The first cookies were created by accident, according to food historians. Cooks used very small amounts of cake batter to test their ovens. These were called "koekje," meaning 'little cake' in Dutch.

In a recent survey at Best-ever-cookie-collection.com , the best-selling cookie of the 20th century was developed in 1912. Take our quiz to see if you know which one it is!

By the way, there are about 25 different kinds of Oreo Cookies. What's your favorite?
