All of the Oreo flavors, ranked

On March 6, 1912, the first Oreo cookie was sold to a grocer in Hoboken, New Jersey. Believe it or not, the chocolate creme cookie was a knockoff of the Hydrox, not the other way around. But every year since its introduction, the Oreo has been the best-selling cookie in the United States. Hooray, America! (Sorry, local bakeries!)

In its history, the Oreo has gone through some major changes. In the early '90s, the lard in the recipe was replaced with partially hydrogenated vegetable oil. In 2006, fear over trans fats forced an ingredient change to non-hydrogenated vegetable oil. That might be why our favorite cookie tastes a little different from what we remember as kids—I mean, we love lard and trans fats in our desserts. In July 2016, believe it or not, the last Oreos were made in Chicago—in the same place where at least some Oreos have been made since 1953. To salute this delicious miracle of chemistry, we hunted down all of the Oreo flavors we could find to see which one was truly the best. Before you head to the candy store, see how they ranked.
