Cake mix is not only an American invention, predominantly sold by American companies (even in the European market), featuring traditionally American baked goods. (Pound cake, brownies and chocolate chip)

Looking for cake mix history in sweden descibe its initial import from USA and England as American style cookies and brownies became popular.

Its American association is well founded. And i did not use the word wierd. I simply pointed out that this ubiquity of "cake mix" baked goods is not reflected in my experience, and may be more concentrated in USA.

In particular in take issue with phrasing cake mix as "family recipe" as even the brands i can find at my store are younger than one generation, and has nowhere near the cultural footprint that they seem to have in USA.
