Interestingly, there is a cake like this in most European cultures. Irish, English, Italian, Spanish and I think Hungarian. A basic, no-cook cake or just a big, chocolate- covered cookie.
I will have to research what the Italian version is. I guess my aunts didn’t know how to make that one :-) I’m actually I remember my favorite aunt made something with hazelnuts that had been biscotti in them. Not crumbled, but layered. That’s what they called the plain crackers. Or cookies rather
