UK mandates "chocolate flavour" labels on low-cocoa biscuits, reflecting shrinking sizes and rising prices amid public nostalgia.

UK regulations now require certain chocolate biscuit bars like Jacob’s Club and McVities Penguin to be labeled “chocolate flavour” due to lower cocoa content, sparking nostalgia amid ongoing shrinkflation. Products like Mars bars have shrunk from 68g in the 1980s to about 51g, with unchanged packaging fueling consumer frustration over higher prices and reduced portions. While iconic treats such as Cadbury’s Flake, Tunnock’s wafers, and Fry’s Chocolate Cream remain largely unchanged, many Britons recall them through nostalgic advertising and childhood memories, highlighting a shift in confectionery standards over decades.
