There is something deeply personal about a discontinued cereal. It is not just a product that vanished from a shelf – it is a Saturday morning memory, a cartoon tied to a bowl of milk, a flavor that no modern substitute can quite replicate. Cereals can be time capsules of how people ate breakfast in a certain era, and for a variety of reasons – economic, social, and cultural – some just don’t exist anymore. The brands below each carry a distinct story of rise, decline, and the stubborn nostalgia that refuses to let them be forgotten entirely.
1. Oreo O’s – The Cookie Cereal That Keeps Disappearing
Oreo O’s is a breakfast cereal consisting of Oreo-flavored O-shaped pieces. It was conceived by an Ogilvy & Mather NYC advertising employee and introduced in 1997 by Post Cereals. For an entire decade, it was a staple of American breakfast aisles, thriving on the simple but brilliant concept of turning a beloved cookie into a morning ritual. Contrary to popular belief, Oreo O’s were not discontinued due to declining sales – the discontinuation was simply a byproduct of Kraft selling Post, its cereal division, in 2007.
In 2012, Oreo’s parent company changed from Kraft to Mondelēz International, opening the door for an Oreo O’s comeback. Five years after the parent company switch, Post Vice President of Marketing Roxanne Bernstein announced that Post and Mondelēz International would be collaborating to bring the cereal back in 2017. The comeback was short-lived, though. In late 2024, news spread that Oreo O’s were being discontinued again to pave the way for the release of Oreo Puffs. A representative told the Food Network that they were eliminating Oreo O’s to make room for a new Oreo-inspired cereal hitting shelves: Oreo Puffs.
2. Waffle Crisp – The Fan-Powered Revival That Still Feels Elusive
Waffle Crisp is a breakfast cereal made by Post Consumer Brands, containing maple syrup-flavored corn cereal bits in a waffle shape. It was first launched in 1996. For a generation of kids who grew up in the late 1990s, it had an almost cult-like following. The cereal combined the flavors of a diner breakfast – warm waffles drenched in maple syrup – with the convenience of a bowl and milk. Cereal connoisseurs and brand loyalists alike had been persistent in their quest to get this childhood favorite back for good after it was discontinued in 2018.
For years, fans of Post Cereals’ Waffle Crisp voiced their desire to see the cereal back on store shelves, sharing their love on social media and even starting petitions to try to bring back their favorite cereal. The pressure worked, at least for a time. After being discontinued, the 2021 relaunch of the iconic cereal was initially a limited-edition offering. However, Post announced in 2022 that Waffle Crisp would be returning permanently with an initial rollout at Walmart and other nationwide retailers following suit later in the summer. Currently, it appears that Waffle Crisp is now available at various retailers nationwide, although some social media users note that it’s pretty hard to find.
3. Smurf-Berry Crunch – The Blue Cereal That Left Behind a Colorful Legacy
Launched in 1983, Smurf-Berry Crunch featured red and blue berry-shaped pieces that were so vibrant they seemed almost magical – just like the cartoon characters themselves. The cereal arrived during a genuine cultural explosion around The Smurfs franchise. In 1982, Smurf-related merchandise made more than $700 million. Riding that commercial wave, Post partnered with General Foods to deliver a fruit-flavored cereal in berry red and deep blue that turned the milk in your bowl a soft, purplish pink color.
According to some sources, Smurf-Berry Crunch had the unintended side effect of turning one’s fecal matter a dark blue color, the same color as the cereal’s titular Smurf creatures, which is why it inevitably left store shelves. This unusual side effect was attributed to the blue dye used in the cereal. Post Cereals tweaked the formula for the cereal, re-releasing it as Smurf Magic Berries in 1987, before that too fizzled out in Saturday morning history. The cereal was discontinued in 1987 and replaced with Smurf Magic Berries, which had marshmallows, but that didn’t last long either. Despite its short lifespan, Smurf-Berry Crunch will always hold a special place in many hearts and memories.
4. Nerds Cereal – Candy at Breakfast, and Gone Far Too Soon
Nerds Cereal was launched in 1985 by the Willy Wonka Candy Company. It was basically candy disguised as breakfast. The cereal was a colorful, dual-flavored breakfast option based on the popularity of Nerds candy. The concept was genuinely inventive for its time – a direct translation of the dual-chambered Nerds candy box into a cereal format. Ralston-Purina attempted to translate this to the cereal set in 1986, offering up two bags of flavors per box, with grape and strawberry, and orange and cherry as the pairings.
The cereal had some success in the beginning but was eventually discontinued around 1988. There were many health concerns over its high sugar content and artificial coloring. Consumers were also shifting to healthier breakfast alternatives at the time. Ralston pulled this gem from shelves in the late ’80s, likely because parents finally realized they were basically serving candy for breakfast. Despite that, the cereal has maintained a devoted cult following for decades. Fans consistently bring it up in online nostalgia threads, and no true successor has emerged to fill the tangy, crunchy void it left behind on cereal shelves.
