I am increasingly interested in Polish cuisine, of what little I know, they are all exquisite, but there are relatively few info to be found, unfortunately, and I suspect as Lulu, I may not be typing in the correct spelling when I google.
One of the wonderful Polish cakes a friend from Krakow taught me was called Pychotka, though I never managed to find any further information from the net or anywhere, this remains one of our special favourite, and while it differs a bit from Lulu's cake, the basic ideas seem like similar.
I have once posted the recipe
here, you might ask her about this too and see if she is familiar with it
