The history of the Oreo is pretty cool as well. It all began in 1912, and originally the Oreo was a mound-shaped cookie and “available in two flavors; lemon meringue and cream”. The cream variety won out, and over the years the Oreo changed in shape and consistency, ballooning to countless varieties such as “double-stuff”, “strawberry milkshake”, and “blueberry ice cream”, to name a few. Products which contained or were inspired by Oreo cookies range anywhere from ice cream flavors to pie crusts. For more information on the history, as well as speculation as to the origin of the name, check out the Wikipedia article.
NOW, here’s the goods. This is easy enough, essentially make an even number of cookies, then sandwich the filling by wiggling the two halves together.
