Why Were Oreo O's Discontinued? (And Why Korea Still Has Them in 2026)

If you grew up in the US in the late '90s or early 2000s, Oreo O's might be a core childhood memory — and then it vanished. What most people don't know is that for a big chunk of that time, the cereal never actually died. It just moved to Korea. As a Korean, I've watched Americans treat this like a lost artifact while it sat on our grocery shelves the whole time. Let me explain the weirdly corporate reason why.

Why were Oreo O's discontinued? The rights loophole, explained

Oreo O's launched in 1997 as a team-up: Post owned the cereal recipe, and Kraft (now Mondelez) owned the Oreo name. In 2007 the two companies stopped co-branding, and because neither side would hand over its half, the cereal became impossible to make — so it was discontinued almost everywhere.

Almost. In South Korea, Oreo O's is produced under a separate license by Dongsuh Foods, an arrangement that wasn't affected by the US split. So while the rest of the world lost it, Korea just… kept going. During the roughly decade-long drought, homesick fans abroad paid $10–20+ a box on eBay to import it from Korea. It became the internet's favorite "you can only get it in one country" snack.

In 2017 Post brought it back worldwide, and for a while everyone could buy it again. Then, on December 4, 2024, Post announced it was discontinuing Oreo O's again to make room for a new product called Oreo Puffs. Production wound down through 2025. And just like that, North America is back to square one.

Here's the twist most Americans miss: the UK never lost it. Over there, Oreo O's is made under a separate Mondelez license (by a UK-based cereal operation, not Post US or Korea's Dongsuh), and it sits on normal supermarket shelves at Tesco, Asda, and Morrisons for around £2 a box. So there are effectively a few different "Oreo O's" in the world — Korea's, the UK's, and the now-ended North American one. The recipes and makers aren't identical, but they're all cookies-and-cream cereal.

The wild part is the price gap. A Brit grabs a box for roughly £2 (about $3) at the corner supermarket. An American in 2026 is usually staring at a $25–30 imported box — because once it has to cross an ocean, shipping does the damage. Same cereal, wildly different receipt.

So where is it actually sold right now?

The flavor nobody outside Korea gets

Here's something that doesn't show up in any of the "Oreo O's is back!" articles. Korea doesn't just make the original — it makes variants. Right now on the same shelf, next to the regular blue bag, there's an Oreo O's Yogurt Cube version: the same cookies-and-cream rings, but with freeze-dried strawberry-yogurt cubes mixed in.

So the situation is even stranger than "America lost a cereal." America lost a cereal that has since branched into flavors Americans have never tasted.

How to actually get Oreo O's in the US (2026)

Since the North American version is gone, and shipping a £2 UK box across the Atlantic makes no sense, what you're realistically buying in the US now is an Asian-market import (usually the Korean one). Best places to look:

• Korean / Asian grocers — H Mart and Weee! often stock the Korean boxes, usually at the friendliest price.
• Amazon & eBay third-party sellers — convenient, but import boxes can run a premium (I've seen $25–30 a box). Check the price and expiration date before buying.
• Specialty snack importers — smaller shops that bring in Korean snacks directly.

Because it all depends on imports, stock and price bounce around. If you see it at a good price and you love it, grab it — the box you're looking at today might be gone next week.

What it actually looks like in the bowl

Dry, the rings are darker than you'd expect — properly cookie-coloured, with white specks through them. Add milk and it does the thing everyone remembers: the milk turns grey-brown and tastes like the bottom of an Oreo glass.

Bottom line

Oreo O's isn't really "gone" — it just left North America. The UK still sells it cheap, and Korea still makes its own, so the cereal you remember lives on. If you're chasing that cookies-and-cream nostalgia in the US in 2026, you're chasing an import — so check the Asian grocery aisle first, and don't be shocked by the price.
