From Polish-based confectioner, PPC Tago, comes "Czekoladowe Muzy" (Don't ask me how to pronounce it!)
These are creme-filled wafers covered in chocolate.
There are two varieties, one with filled with coconut-creme, and the other filled with vanilla creme.
They're being distributed to the USA and several other countries. You'll probably have to find them in imported goods stores.
