Oreo releases 'mystery' flavor that tastes kind of familiar...

Oreos are one of the most diverse cookies on the snack shelf.

While most of us are accustomed to the traditional chocolate-cookie with vanilla-creme in the middle, there are literally dozens of other possible flavors that have been floated over the years, from Avocado Oreo to Firework Oreo.

But today, Oreo may be prepared to top all of them ... by releasing a mystery flavor!

Kathie Lee and Hoda try mystery Oreos: Can you guess the flavor?

    The totally mysterious cookie, which hits shelves on Monday Oct. 9, is a limited-edition treat that Oreo won't even explain to TODAY!

    The all-white package offers no clues as to what the flavor could be, because Nabisco wants you, the true Oreo fanatic, to guess what the flavor is. What is this cookie sorcery, anyway?! The cookie itself looks like a plain Oreo (albeit a Double Stuf one), but many people think it tastes like some kind of fruit-flavored cereal, a la Fruity Pebbles or Fruit Loops.

    TODAY's Kathie Lee Gifford and Hoda Kotb gave the mystery flavor a try and both thought it tasted like watermelon. "Some sort of a melon," Kathie Lee said. But Oreo already came out with a limited-edition watermelon flavor in 2013.

    20 Oreo flavors you had no idea existed

    Waffles & Syrup Oreos

    This limited edition cookie is only available in Albertsons stores. The outside cookies are Golden Oreos, while the cream appears to have a dot of syrup in the center.

    Firework Oreo

    Oreo is hoping this cookie will be "fireworks" in your mouth! At the center of the cookie, blue-and-red "popping candies" (think Pop Rocks) are mixed in with the creme. 

    Dunkin Donuts Mocha Oreos

    It just makes sense: Dunkin' Donuts Mocha Oreos are coming this summer.

    Strawberry Oreo

    While the Oreo looks like a chocolate-filled cookie, twist that baby open and you'll find a dollop of artificially-flavored strawberry cream at the center.

    Milka Oreo Big Crunch Chocolate Candy Bar

    Oreo's first candy bar ever, this bar features a crunchy layer of the classic Oreo chocolate cookie that's surrounded by vanilla cream and coated in silky Milka milk chocolate.

    Oreo Swedish Fish flavor

    "Moment of truth: Oreo may have jumped the shark with the Swedish Fish flavor. It wasn't what I was hoping for so I made the rest of the TODAY team taste them too. A majority of the editors couldn't finish a full cookie, but two die-hard Swedish Fish fans were thrilled with the taste and couldn't get enough of them," TODAY Food editor Alessandra Bulow writes.

    Oreo Choco-Chip Cookies

    The first Oreo with dual-flavored wafer, this cookie has a pretty marble-like swirl of vanilla and chocolate and flecks of chocolate. Then there's the filling, which has a hint of chocolate flavor and is studded with tiny chocolate bits.

    Skinny Oreo cookies

    These cookies are about half the width of the original, though the circumference remains the same (so we're not quite in Mini Oreo territory), and they come in original, golden and mint varieties. 

    Fruity Crisp Oreos

    The cream in these sandwich cookies is combined with a fruity and colorful rice crisp.

    The Blueberry Pie Oreo

    These graham cracker sandwich cookies are filled with blueberry cream.

    Strawberry Shortcake Oreos

    "As 'The Golden Girls' taught us in the episode where Rose makes a midnight snack of Sperheoven Krispies, some treats taste much better than they smell — and that's the case for these. While the strawberry cream filling was cloying at first whiff, a bite of the full cookie was far more pleasant." —Erin Clements, Senior Pop Culture Editor

    Oreo debuts Filled Cupcake Oreos

    The Filled Cupcake Oreo is reminiscent of another beloved treat, Hostess' iconic cream-filled chocolate cupcake. Oreo's take features two of its regular cocoa wafers sandwiching chocolate frosting with a dollop of vanilla cream in the center.

    New brownie batter Oreos

     While the rest of the cookie is pretty similar, if not identical, to the original Oreo, the stuf is distinctly "brownie batter." How on earth did they manage to replicate that creamy, chocolaty and uniquely "brownie" flavor with such precision?

    Jelly Donut flavored Oreos

    Introducing the Jelly Donut Oreo, a Golden Oreo cookie with a raspberry center and custard outer ring. And the only place you’ll be able to get your hands on it is Walmart; it’s an exclusive to the store.

    The Peeps Oreo

    For this cookie, Oreo went with a pretty pink marshmallow-and-sugar-crystal Peeps filling between two vanilla cookies.

    The Cinnamon Bun Oreo

    This cookie features cinnamon-spiced frosting sandwiched between two golden cinnamon wafers.

    The Pumpkin Spice Oreo

    The makers of the classic Oreo cookie had to make sure they had that autumn-essential flavor covered. 

    The Red Velvet Oreo

    This red-tinged chocolaty cookie with a cream cheese spin on the "creme" filling got an overwhelmingly positive response at our taste test.

    The Reese's Peanut Butter Cup Oreo

    What if an Oreo and a Reese’s Peanut Butter Cup had a baby? That’s the stuff dreams are made of. And thankfully, the cookie conception of your dreams became a reality.

    The S'Mores Oreo

    The cookie portion of the Oreo is “graham flavored,” and sandwiched between are layers of chocolate and marshmallow flavored “creme” filling.

    Nabisco describes the cookie as the “newest, and spookiest, new limited-edition flavor,” which could mean the flavor is a candy-related to tie in to Halloween. Or it could be a combination of two of its previous limited edition flavors (maybe the watermelon flavor mixed with something else?), because that's (sort of) how Dum Dums' mystery flavor is made: Instead of shutting down machinery and completely emptying out a batch's flavor, sometimes they'll just start a new batch, and, as a result, the two flavors will overlap for a little bit.

    You'll want to find out for yourself, of course, because in another bit of marketing wizardry the company is awarding $50,000 to the person who guesses the flavor correctly!

    Using your Oreo obsession to pay your bills? Now that’s the “Stuf” dreams are made of.
