This bumper triple pack of McVities Jaffa Cakes will keep even the most ardent Jaffa Cake-loving family busy for a while. This popular snack comprises a sponge cake base, a layer of tangy orange flavoured jelly, and a delicious chocolate coating.The prickly question of whether Jaffa Cakes are biscuits or cakes actually found its way to court, due to the UK Law stipulating that VAT should be applied to all chocolate covered biscuits - whilst plain biscuits and cakes remain exempt.Thankfully, Jaffa Cakes were proven to be cakes, simply because they go hard when stale (biscuits, in contrast, go soft) - thus keeping them free of VAT!
