Combine flour, baking powder, starch, soda and vanilla essence. Add a little water to make the dough liquid.
Cut bananas into medium slices.
Dip each slice of banana in the cooked dough.
Heat the oil well in a pan and put the bananas, cook until golden.
For caramel, pour sugar into a pan, add water and keep on medium heat until the caramel is golden brown.
Dip each piece of banana in caramel and immediately lower it into very cold water with ice so that the caramel quickly grabs and freezes. Bananas in caramel sauce are ready, sprinkle with sesame seeds and can be served.
