Kellogg's Crunchy Nut

Brand origin and product

Kellogg's Crunchy Nut is a breakfast cereal first created at Kellogg's Trafford Park factory in Greater Manchester and introduced in 1980; it is a sweetened corn-flake style cereal coated with honey/sugar and mixed with chopped peanuts. (en.wikipedia.org)

Manufacturing

The Crunchy Nut product is manufactured for the UK market in the United Kingdom (historic production at Trafford Park and ongoing production/expansion at Kellogg/Kellanova's Wrexham facility). Recent company plans and investment mean UK production of Corn Flakes and Crunchy Nut is centred at the Wrexham plant while Trafford Park operations are being wound down, so the cereal is primarily made in the UK though the brand is produced in multiple countries for different markets.

Brand and ownership history

The Kellogg brand was originally founded in the United States (Battle Creek, Michigan) by the Kellogg Company. Crunchy Nut itself was developed in the UK as an innovation from Kellogg's Trafford Park R&D team. (britannica.com)

Current ownership (ultimate owner)

Following corporate restructuring and transactions in the 2020s, the international cereal business that markets Crunchy Nut outside North America was held by Kellanova (the rebranded global business spun out of the original Kellogg company) and that business was acquired by Mars, Inc.; as a result, Mars is the ultimate owner of the international Kellogg cereal portfolio (including Crunchy Nut) as of December 2025. The operating entity in the UK is commonly referenced as Kellanova / Mars Snacking. (en.wikipedia.org)

Summary

Kellogg's Crunchy Nut — a UK-created Kellogg's cereal — is primarily manufactured in the United Kingdom for the UK market (with production networks elsewhere for other markets). The brand traces back to the US-founded Kellogg Company, and the international Kellogg cereal business that manages Crunchy Nut is operated under Kellanova/Mars Snacking following Mars, Inc.'s acquisition in late 2025.
