Country Style Foods has acquired the former RHM frozen desserts business from Premier Foods for an undisclosed sum.
The deal includes a factory in Flint, north Wales, which has 200 staff, and a licence to produce Cadbury branded products. The operation also produces own label products for supermarkets.
Country Style, which has annual sales of £80m, supplies Asda, Tesco, Morrisons and Sainsbury's with own label baked goods and desserts. It also has the license for Sara Lee's frozen desserts. Director Joe Wood said he believed there was potential to expand the Cadbury frozen cakes and desserts range.
