Limited-time Super Mario Oreos feature iconic characters on classic cookie.

Oreo has announced a limited-edition cookie collaboration with Super Mario Bros. featuring 16 unique embossments of characters like Mario, Luigi, Yoshi, Goomba, and Bowser Jr., as well as power-ups like Super Stars and Fire Flowers. The cookies will be available at retailers nationwide starting July 10 for a limited time. Oreo is also holding a social media event where they're asking those who buy the cookies to stack as many of the hero-embossed cookies on the rim of a glass of milk without the cookies falling into the milk and share the video on social media in a concerted effort to save Princess Peach from Bowser's Castle.
