Limited edition Oreo flavors include: key lime, s'mores, red velvet, cotton candy, birthday Oreos, caramel apple, limeade, pumpkin spice, root beer float, Reese's peanut butter cups and more. The key lime, s'more, red velvet and cotton candy Oreo cookies are new flavors for 2015 and come in the same form as original Oreo cookies. Oreo releases flavors on a seasonal basis and to commemorate certain events, such as Gay Pride day, movie releases and Bastille Day.
For the summer of 2015, Oreo released a s'mores and key lime version of the original Oreo cookie. Key lime Oreos have a green, lime-flavored filling sandwiched between two round graham crackers. The s'mores Oreos also have round graham cracker cookies on the outside, and a filling of chocolate and marshmallow creme.
Limited edition Oreos in past years also came in summer-themed flavors, such as root beer float, cotton candy, limeade and fruit punch. Root beer Oreos have vanilla-flavored cookies and root beer-flavored creme. Cotton candy Oreos have graham cracker outsides with purple and pink creme; these limited edition Oreos are sold exclusively at Target. Fruit punch and limeade Oreos also have vanilla cookies; the first has a punch-flavored creme filling, while limeade Oreos have a lime center.
In February 2015, the company created red velvet Oreos with chocolate cookies filled with red cake batter-flavored creme. Other seasonal specialties include caramel apple Oreos and pumpkin spice Oreos. The former has graham cracker cookies and pumpkin-flavored creme.
