Kellogg’s is changing the recipe for its iconic Rice Krispies cereal in the UK, replacing whole rice grains with rice flour, as weather-related disruptions affect ingredient supplies.
Kellanova, the company responsible for Kellogg’s cereal brands outside of North America, has also reformulated its Coco Pops – aka Cocoa Krispies in the US – by replacing whole rice grains with a combination of rice flour and corn flour, according to British food publication The Grocer.
The changes will not affect Rice Krispies sold in the United States or Canada, WK Kellogg Co. confirmed to FOX Business.

“Kellogg’s Rice Krispies cereals sold in the United States and Canada are not affected by the recently announced recipe changes for Kellogg’s Rice Krispies and Kellogg’s Coco Pops cereals in the United Kingdom,” a company spokesperson said in a statement.
WK Kellogg Co. said its Rice Krispies, Cocoa Krispies and Frosted Krispies cereals sold in North America will continue to be made with real rice without changes to their ingredients or recipes.
The two companies separated in 2023, when the former Kellogg Company split into Kellanova and WK Kellogg Co. Mars acquired Kellanova in December 2025. Ferrero acquired WK Kellogg Co. in September 2025.
Kellanova said the reformulation aims to maintain consistent product quality, as changing weather conditions affect the availability and quality of certain grains.

The updated British recipes also contain wheat gluten, making the cereal unsuitable for consumers with wheat allergies or celiac disease.
The company said the cereal continues to meet UK nutritional standards for fat, salt and sugar, whilst retaining its previous levels of fibre, vitamin D and iron.
Sales of Rice Krispies have also declined in Britain, according to The Grocer, although the company has not linked the reformulation to the sales decline.

Other major cereal manufacturers have also updated their recipes. General Mills announced in August that its American cereals, including Lucky Charms and Trix, no longer contain certified synthetic colors.

The company plans to eliminate these additives from its entire U.S. retail portfolio by the end of 2027.
A representative for Kellanova, which oversees British cereal brands, did not immediately respond to FOX Business’ requests for comment.
