@Majestic Glad you liked Dalmatia.

Oh, haha! Didn't expect anyone would ask me about Croatian language! Glad I can return the favor!
I am not familiar with "povitica", never heard the word. Internet tells me it's actually Slovenian pastry which is a neighbor country so probably that's why I haven't heard of it.
"Gibanica" is a pastry that would traditionally be made with cheese.
The pastry from your picture is classic "orehnjača". We use this interesting letter Č, that is pronounced "ch" (so the whole workd is "o-reh-nia-cha")
Orah (or archaic "oreh") means walnut, hence the name. Light part is some kind of sweet bread and the dark part is a mixture made from walnuts. My grandma used to make it, never liked it that much, hahaah...
