This little thing is so nice and tasty, I have been loving them since I was a kid.
My mother always tended to go to the same small asian supermarket around Maubert Mutualité. The little lady taking care of it knew her well, and told her several times, that these soy and banana "cakes" were extremely easy to make.

It is a rich paste which melts as soon as you place it in your mouth. It also as the same sort of gooey feel than rice paste within softness and the sweet taste of it. However, this specific one is entirely cream and the layers don't feel separated.
