Kellogg's Receives Backlash After Altering Rice Krispies and Coco Pops Recipes

Cereal manufacturer Kellogg's has altered the formula for its flagship UK breakfast cereals Rice Krispies and Coco Pops, replacing whole rice grains with flour blends following global grain supply issues caused by extreme weather.

The updated recipes swap out whole rice grains in favor of rice flour for Rice Krispies, while Coco Pops now features a combination of rice flour and corn flour. The changes have drawn backlash from long-time consumers online, with many reporting that the cereal's famous sound effects, which have been a staple of the brand's marketing since the 1950s, have noticeably quieted or disappeared entirely upon adding milk.

A company spokesperson acknowledged that maintaining the traditional sound was a key priority during development, but conceded that consumers "might notice that the sound may be quieter and not as instant as before".

The company elaborated on the recipe overhaul in an official statement:

"We have updated the Rice Krispies and Coco Pops recipes, which are now made using corn flour and rice flour.vThis recent change helps us maintain consistent quality at a time when changing weather conditions are affecting the quality and availability of some of the rice and grains used in our cereals."

"We appreciate that even small changes to a much-loved product can feel noticeable and that’s why we have approached this with a lot of care and consideration. The updated recipes have been carefully assessed for taste, appearance and texture, and we are continuing to listen closely to consumer feedback."

The recipe adjustment triggered a wave of dissatisfaction across social media platforms, with parents and regular consumers criticizing the altered texture, taste, and reduced acoustic feedback.

Beyond changes to texture and sound, the reformulation has altered the cereal's ingredient profile. Because wheat gluten is now directly added as an ingredient, the cereal is no longer suitable for individuals with coeliac disease or wheat allergies.

While previous packaging carried a general warning stating the products "may contain gluten" due to shared facility cross-contamination risks, boxes now feature prominent bold labeling indicating that the product "contains wheat gluten" as a direct allergen.

Kellogg's noted that the cereals remain non-HFSS (not high in fat, salt, or sugar), contain no artificial colors, flavors, or sweeteners, and retain their original levels of iron, vitamin D, and dietary fiber. The recipe change applies exclusively to the UK market, leaving North American versions unchanged.

The operational decision follows severe climate events in key agricultural regions, including droughts in Spain and weather disruptions across South East Asia tied to El Niño. The shift also comes as sales data for the brand shows declines in both overall volume and total value according to industry trade figures from The Grocer magazine.
