Oreo celebrates Mickey Mouse's birthday with new cookie flavor

To celebrate Mickey Mouse's big 90th anniversary, Oreo is releasing a brand new Birthday Cake flavored Oreo cookie. 

Oreo is teaming up with Disney to celebrate America's favorite mouse with the limited-edition cookies featuring three different Mickey Mouse-themed designs on top of the Oreo wafers, starring the birthday boy himself. 

There will also be two other festive designs.

The cookies will be available beginning September 24 while supplies last.
