this is a savory sandwich cake made with layered crustless sandwich bread, "icing" (made with flavored cream cheese, sour cream, creme fraiche etc) and filled/topped with feta cheese, tomatos, cucumbers etc.

Voileipäkakku - Finnish sandwich cake. (Just pic) Built just like a normal cake but with savoury ingredients like ham or smoked salmon. Love it <3
