The Japanese have a queer way of doing things, not always but often when it comes to language they twist the English language by misusing a word and or re-writing the word. In the golden era there was a well-known ryokan in Atami that served corn freaks for breakfast if you know what I mean.
This is a cookie or is a bun and or both. It is a chocolate chip cookie covered by a bun of some kind. An anomaly in Japan is classical and happens more than often in a place that is more perfect than perfect – go figure.
Another version of crazy buns hidden beneath a chocolate highway.
