McVities Jaffa Cakes are an iconic British snack that is loved by kids and fondly remembered (and still enjoyed) by adults! They consist of a sponge cake base, topped with a layer of tangy orange flavoured jelly, and rounded off with a 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!
