Are you aware that the cake she was and you are referring to is not the birthday sort........aka let them eat poo kind of “cake”......:o)
No, but, same difference!
My mother, who was of french descent, used to make brioche. We would slather it in butter and eat it for breakfast with coffee. It was slightly sweet but I would still consider it in the bread family. I've never heard the interpretation of which you refer.
