Oreo flavors you'll sadly never get to try again

Nabisco is not afraid of experimenting with its Oreo flavors. Since 1912, the snack food company has created so many different variations of its beloved chocolate sandwich cookie, including holiday-themed and limited-edition flavors, mystery flavors, a version branded by streetwear label Supreme, and even glittery Oreos. Nabisco's willingness to reinvent the Oreo and keep fans interested with new releases has led to the cookie being sold in over 100 countries and earning the title of best-selling cookies in the world.

But just because a new flavor is a winner among consumers, though, doesn't always mean it's here to stay. There have been many flavors of Oreos that have been discontinued over the years, and we are taking the time to wistfully remember their deliciousness. Here are some Oreo flavors we will unfortunately never get to try again.

Lemon Meringue and Uh-Oh! Oreos

When Oreos first debuted in the early 20th century, Nabisco not only released the original but also Lemon Meringue — vanilla cookies with a tart and creamy center based on lemon meringue pie. Though both flavors were a hit among customers initially, the chocolate Oreo soon came out on top in popularity (via BabbleTop). The Lemon Meringue flavor was discontinued in the 1920s, according to TIME. The regular Oreo has stood the test of time, but fans of the cookie can't help but wonder what the other classic flavor tasted like.

Vanilla-flavored Oreos are common today, but back in 2003, they were still a novel concept. Nabisco developed a new kind of Oreo that year: chocolate cream sandwiched between two vanilla biscuits — dubbed the Uh-Oh! Oreo. Nabisco created a backstory for the product and depicted it in a commercial, which shows a worker at the Oreo factory accidentally breaking the machine. The mishap results in inverted Oreos, with chocolate replacing vanilla in the cream filling and vice-versa for the cookie layers. A year later, these Oreos were rebranded to "Golden Uh-Oh! Chocolate" and another type of Uh-Oh! Oreo was also created but with vanilla filling instead, as seen in Mental Floss. The latter became the Golden Oreo that we know and love today, but its chocolate counterpart was eventually pulled off the shelves.

Big Stuf Oreo

In 1984, Nabisco took "more is better" to a new extreme with the introduction of the Oreo Big Stuf, which was about 10 times the size of a normal Oreo. Big Stuf cookies were sold in a box of 10, with each packaged individually. But the sizable creation was discontinued after seven years. Fast Company offered a few possible reasons why. One was that the Big Stuf was just too big for its target demographic. It took 20 minutes to eat an entire Big Stuf, according to reviewers, and that was way too long for a kid or even an adult to spend snacking on one humongous cookie.

Also, those who enjoy Oreos usually twist the cookie apart to taste the center first, dunk the whole cookie in milk, or do a little bit of both. However, with such a large cookie, consumers couldn't do their usual habits easily. They either had to eat a lot of the Big Stuf before pulling it apart or break it into pieces to fit into a glass of milk. And with the release of new USDA dietary guidelines and the Food Pyramid in the '80s, people became more health-conscious and less willing to treat themselves to a gigantic Oreo that contained 316 calories and 13 grams of fat. But in today's world of viral food challenges, the Big Stuf would fit right in.

Oreo Magic Dunkers and Dunkers

2000 was a magical time when your Oreos turned your milk blue (yes, you read that right). For two glorious months that year, Magic Dunkers were available (via Weird Universe). According to Food Ingredients Online, Nabisco technologists spent more than a year designing these Oreos to get the blue milk effect without changing the flavor of the cookie or the milk it's dunked into. Supposedly, the more times you dunked this Oreo, the bluer the milk became. Where did the blue come from? Jessica Aronofsky, then a Nabisco senior cookie technologist, said that the blue food coloring was just like the kind used for popsicles and candies and that it was safe and would easily fade from hands and mouths. These Magic Dunkers were short-lived and haven't appeared since, but we wish this colorful Insta-worthy product would see the light of day again.

Oreo Dunkers didn't turn milk blue. Nabisco created them as a more convenient version of the classic cookie. To appeal to people who like to dunk their Oreos, for whom the traditional cookie either didn't fit in glasses or left fingers milky and wet, the company designed a narrower, elongated Oreo in 2006. Dunkers didn't last, so we just have to continue dunking our Oreos the old-fashioned way.

Double Delight and Red Velvet Oreos

Nabisco mixed things up with the release of the Double Delight Oreo in 1987. The cookie's filling was one half chocolate, one half peanut butter (which honestly sounds like the best of both worlds to us). This flavor was eventually discontinued, but then revived later in 2003, along with the introduction of two other Double Delight flavors: Mint 'n Creme and Coffee 'n Creme. All versions are gone now, leaving fans with single-filling Oreos.

More recently, Thrillist bemoaned the demise of Red Velvet Oreos, which had been placed highly on its past Oreo flavor ranking list. A rep for Oreo told the publication that Red Velvet Oreos were being discontinued to make room for other new flavors and products. But it's hard to let go of an Oreo that tasted like one of the most delicious and well-known cakes, and some consumers are still begging for its return.
