National Oreo Cookie Day - March 6


Be ready to observe by having your glass of milk handy as it is National Oreo Cookie Day. This day is recognized across the nation each year on March 6th.

The Oreo sandwich cookie is made up of two chocolate disks containing a sweet cream filling and is loved by millions. Since its introduction, the Oreo cookie has become the best-selling cookie in the United States.

The National Biscuit Company (today known as Nabisco) first developed and produced the “Oreo Biscuit” in 1912 at its Chelsea factory in New York City. Today, the block on which the factory was located is known as “Oreo Way.”

  • The name “Oreo” was first trademarked on March 14, 1912.
  • The first Oreo cookies in the United States sold for 25 cents a pound in clear glass topped novelty cans.
  • In 1912, the Oreo Biscuit was renamed “Oreo Sandwich.”
  • In 1948, the Oreo Sandwich was renamed “Oreo Creme Sandwich.”
  • William A. Turnier developed the modern-day Oreo design in 1952 to include the Nabisco logo.
  • Nabisco’s principal food scientist, Sam Procello, developed the modern Oreo cookie filling.
