Food / Looking for recipe for Murzynek layer cake [6]

I had a wonderful chocolate layer cake ( layers were drenched in a sugar solution ) with a cooked milk frosting. I think it was called Murzynek. Can someone post a recipe in English?

I looked up the meaning and it is also means something like a brownie. But I am looking for the moist chocolate layer cake recipe and not a brownie. I found a few recipes on the Net but none like the elegant layer cake I had

Thanks for any help!
