Question: are jaffa cakes getting smaller?
Answer: Jaffa Cakes packet size reduced in latest 'shrinkflation' move. Jaffa Cakes have become the latest casualty of shrinking pack sizes in supermarket aisles. A standard box of McVitie's Jaffa Cakes now contains 10 rather than 12 cakes, while a twin pack has also been put on a diet, dropping from 24 to 20.
