Oreo is Releasing a Strawberry Frosted Donut Flavor Oreo is at it again and getting fans ready for another great flavor!  Oreo will be introducing a Strawberry Frosted Donut cookie in March.  This limited-edition treat will have vanilla cookies on the outside and strawberry and donut flavored cremes on the inside. Even better? it’s also filled with rainbow sprinkles! It’s basically like the Oreo version of a Simpsons donut and I’m here for it!
