Italian confectioner Ferrero, known for brands like Nutella and Kinder, is buying U.S. cereal company WK Kellogg in a deal valued at approximately $3.1 billion.

Italy's Ferrero has continued its U.S. spending spree with its proposed acquisition of famous cereal maker WK Kellogg amid wider food manufacturer consolidation.

The $3.1 billion acquisition would combine Ferrero, which makes Tic Tacs and Nutella, with the producer of Frosted Flakes and Froot Loops.
