Rather than being available for a limited time, the new flavors are meant to be permanent additions to the company's Rice Krispies line that will be rolled out nationwide.
Birthday Cake Rice Krispies Treats feature rainbow sprinkles and a creme drizzle while Cookies 'n' Creme Rice Krispies Treats includes chocolate cookie crumbles and a creme drizzle.
