A cake in a marmelade glass

You have heard about the cup cake, the mug cake, the fork cake (http://umamispark.blogspot.de/2014/01/the-fork-cake.html), but have you hear about the Cake in a marmelade glass?

Kuchen im Glass (litteraly "Cake in Glass") (http://www.kuchen-im-glas.com/), which seems to be a kind of spin of Yoomig, offers several of them. You can buy the cake alone, like the banana - nuts one, or as a set with icing, topings and accessories.
