Oreo

Oreo is a sandwich cookie. Oreo has become the best selling cookie in the United States, through the 20th century and into the 21st.

The "Oreo Biscuit" was first developed and produced by the National Biscuit Company (today known as Nabisco) in 1912 at its Chelsea factory in New York City, which was located on Ninth Avenue between 15th and 16th Streets.
