To make the caramel, heat the sugar in a skillet over low heat, stirring constantly. Once it turns golden brown, add the butter, then the heavy cream and a generous pinch of salt, stirring continuously.

Slice the bananas lengthwise and place them in the bottom of a baking dish. Pour the caramel over the bananas.

In a mixing bowl, combine the eggs, flour, and baking powder. Mix well. Add the yogurts and chocolate chips, then mix again.
