First, take a donut mold and pour in the 160 g of sugar and put on low heat until you get a caramel.
Spread the caramel on the bottom and sides of the mold.
Spread the sliced bananas on the bottom and sides of the mold with the caramel and set aside.
Now pour the milk with the eggs, sugar, butter into the blender and blend for 2 minutes.
Pour the mixture into a bowl and gradually add the flour, mixing well with a whisk.
Then add the yeast and mix gently with a wooden spoon.
Pour the mixture into the mold and bake in a preheated oven at 180 degrees for 35 minutes.
Unmold while still warm so that the caramel does not harden.
