I think they are now known as cupcakes because people feel they have to reinvent the wheel and create new fads and marketing opportunities. The little cakes in paper cases our grans, and mums taught us to make were little different, apart from cup cakes now having piles more oversweet butter cream icing on top, thus adding to the obsesity problem (I do like a good whinge.)
We had fairy cakes, butterfly cakes, Rock cakes, individual chocolate cakes of all kinds. I particular remember some small shop bought cakes with a lovely pinapple flavoured topping I've not seen them for years! Does any one else remember them?
Perhaps we need to think of a new product to promote, out of what to us was a standard old recipe and make our fortunes.
