Interesting thoughts David. In a 2003 newspaper article, food historian Catherine Brown shared:
"But there was nothing to compare with the German pastry cooks' sophisticated use of marzipan, colours, shapes, flavours and allegorical designs. The British were impressed. They tried their hand at the German techniques and some native pastry cooks became almost as good as the Germans. Such was their confidence that when Queen Victoria's granddaughter, Princess Victoria of Hesse-Darmstadt, married Prince Louis of Battenberg in 1884, it was decided that a celebration cake was required, in their own design of course, but appropriately German in style to celebrate the marriage. What else to call it but a Battenberg cake? It was to be unique: a cake to stun British cake-lovers. They took inspiration from the German rococo style of architecture which featured gold (marzipan) with pastel colours (pink and yellow sponge)."
Per Wikipedia:
The cake was purportedly named in honour of the marriage of Princess Victoria, a granddaughter of Queen Victoria, to Prince Louis of Battenberg in 1884. The name refers to the town of Battenberg, Hesse in central Germany and is the seat of the aristocratic family known in Britain as Mountbatten.
