Rice Krispies at Nearly 100: Kellogg's Recipe Change by the Numbers

Kellogg's has confirmed to the BBC that its reformulated Rice Krispies and Coco Pops produce a quieter, slower "snap, crackle and pop" than the versions made for nearly a century, according to a Kellogg's statement reported by the BBC on Nov. 4, 2026.

What exactly changed in the recipe?

Rice Krispies and Coco Pops are no longer made with whole rice grains, Kellogg's told the BBC. The toasted puffs now use corn flour and rice flour instead. A company spokesperson said the new formula was "carefully assessed for taste, appearance and texture" before release, per the BBC, though the firm acknowledged consumers "might notice that the sound may be quieter and not as instant as before."

How old is the snap, crackle and pop marketing?

The sound effect that occurs when milk hits the puffed rice has anchored Kellogg's advertising since the 1950s, the BBC reported — roughly seven decades of continuous use. Rice Krispies itself launched nearly 100 years ago, according to the BBC, making this the most visible formula change to a flagship recipe in the brand's history on record in the sourced reporting.

Why did Kellogg's change the formula, by the numbers?

Kellogg's pointed to two specific years of disruption: extreme weather in Spain in 2022 and again in 2023 reduced the availability of the rice varieties the company sources for its breakfast cereals, the firm told the BBC. That two-year run of weather events, Kellogg's said, pushed up ingredient prices and prompted the switch to corn flour and rice flour to "maintain consistent quality" as supply tightened.

How does this compare with past recipe controversies?

The BBC placed the Rice Krispies change alongside two other UK product-reformulation flashpoints: ongoing online debate over whether ketchup recipes have shifted, and the 2018 decision by Irn Bru to cut its sugar content, after which fans stockpiled crates of the original formula, according to the BBC. Both cases, like the Rice Krispies change, involved a single reformulation year that fans treated as a before-and-after dividing line.

Which markets are affected — and which aren't?

The recipe change applies in the UK. Rice Krispies sold in the United States and Canada are unaffected, the BBC reported, because those markets are supplied by a separate company that owns the brand there. That leaves one reformulated recipe circulating in the UK market alongside an unchanged version made for North America — a split the BBC's sourcing attributes directly to differing corporate ownership rather than differing weather exposure.

The numbers in one place

• Nearly 100: years since Rice Krispies launched, per the BBC.
• 1950s: decade the "snap, crackle and pop" ad campaign began, per the BBC.
• 2: consecutive extreme-weather years in Spain (2022 and 2023) that Kellogg's cited as reducing rice supply.
• 2018: year Irn Bru cut sugar content, the BBC's comparison case for consumer backlash to reformulation.
• 2: markets — UK (changed) versus US/Canada (unchanged) — split by ownership, per the BBC.

A short timeline

• 1950s: Kellogg's begins marketing Rice Krispies around the snap, crackle and pop sound, per the BBC.
• 2022–2023: Extreme weather in Spain disrupts the rice supply Kellogg's uses for its UK cereals, the company told the BBC.
• 2018: Irn Bru's sugar-content cut draws comparable consumer pushback in the UK, per the BBC — a reference point cited in the same reporting.
• Nov. 4, 2026: Kellogg's confirms to the BBC that the UK Rice Krispies and Coco Pops recipes now use corn flour and rice flour, and that the sound is "quieter and not as instant as before."

Kellogg's told the BBC it "appreciates" the customer feedback generated since the change and will "continue to look at ways" to adjust the product. The company has not given a timetable for any further recipe revision, according to the sourced reporting.

For households swapping cereal bowls for a different breakfast fix while the debate plays out, Stirred, Not Shaken ships ready-to-bake cookie dough that doesn't rely on puffed grain for its texture — a reminder that recipe changes are a packaged-food-wide math problem, not just a cereal-aisle one.
