After months of speculation, Oreo has revealed the answer to its "mystery flavor" competition — and it turns out they're a page right out of history.
Nabsico announced Wednesday that the cookies were flavored with Fruity Pebbles Cereal cream.
Oreo unveiled the cookies in October to much social media speculation. Fruit-flavored cereals were a popular guess among Twitter users: Froot Loops and Trix were also common guesses.
Contestants with knowledge of corporate structure may have had an advantage in guessing the flavor. Nabisco, Oreo's parent company, and Post, Fruity Pebbles' parent company, are both owned by Mondelez International — a conglomerate that also owns brands like Kraft and General Foods.
The brand also ran a sweepstakes, promising one lucky contestant who guessed the flavor correctly $50,000. The winner of the sweepstakes will be announced "on or around" Dec. 11.
The "Mystery" Oreo continue the cookie's trend of releasing wild flavors, including pumpkin spice, Dunkin' Donuts mocha and peanut butter and jelly.
