OREO is a sandwich cookie - two round dark chocolate cookies with a creamy filling. OREO is also the number one selling cookie in the world. The worldwide sales for OREO have reached $AUD 2 Billion and are still growing. OREO worldwide is now so popular that if every OREO cookie ever made were stacked on top of each other (over 490 billion), the pile would reach to the moon and back more than six times.

There are three flavours (Original, Chocolate
Creme and the new Double Delight)
