Post Mega Stuf Oreo O’s Cereal contains the same Oreo O’s you know and nodded your head to when it appeared on a BuzzFeed list called something like “49 Discontinued Cereals That We NEED In Our Bowls NOW To Make Milk Taste Better” that you scrolled through many years ago. But, it also has white marbits that symbolize the “Mega Stuf” part of the cereal.

Basically, it’s Oreo O’s with marshmallows. While it’s a Walmart-exclusive for its debut, it’ll end up at other retailers later.

Oreo O’s is already a great cereal, but does the addition marshmallows make it better?

I think so, but they don’t create a vast difference that’ll make you shun regular Oreo O’s and shake your head if you come upon it in a BuzzFeed list called something like “35 Discontinued Cereals You’d Taste Again If You Had A Time Machine.”

The marshmallows add a stronger creme element and a texture that’s different from the crunchy, chocolatey loops that taste slightly reminiscent of Oreo wafers. There are enough of the 1950s medication-looking marbits to ensure there is at least one with every spoonful.

But even with all those white marshmallows, the chocolate-to-creme flavor ratio doesn’t lean more toward the creme as it does with an actual Mega Stuf Oreo Cookie, which can make it a little cloying. Instead, it’s more like Oreo Thins, which I love.

While this is a wonderful cereal, it doesn’t make the milk chocolatey, which is a little disappointing because the same company that makes Cocoa Pebbles Cereal, which could be considered an instant chocolate milk mix, makes this.

If you have a Wikipedia’s worth of cereal knowledge, like these folks, you’d know that Mega Stuf Oreo O’s is similar to Extreme Creme Taste Oreo O’s from 2002 and the cereal sold in Korea that we reviewed several years ago.

Mega Stuf Oreo O’s should be THE Oreo O’s Cereal. With the addition of marshmallows, there’s a better flavor balance between the creme and chocolate that’s more similar to an actual Oreo cookie than the original cereal.
