Princess doughnuts, translated. And apparently it is okay to call them that in English too haha. I didn't think literally translating it would actually be it xD http://themostbeautifulcakes.com/princess-doughnuts/
i would guess cream puff but i see there is 2 types of filling on those and cream puffs here generally just have the one type of filling
I'd just call them cream cakes, to be honest. However I did a modicum of research, and they are also called profiterole, choux à la crème, and a version called Bossche bol otherwise known as a chocoladebol. I would imagine it would be difficult to translate chocoladebol into Croatian. The inside of a Bossche Bol
