For The Cake :
•120g brown sugar
•1 packet of baking powder
•1 C. rum
•50 g walnuts
•the juice of a lemon
For The Caramel :
•150g caster sugar
•2 tbsp. water
➔Sift the flour, baking powder and brown sugar into a bowl. Mix. Add the eggs and mix until you obtain a smooth and homogeneous paste.
➔Melt the butter in the microwave or in a saucepan. Add it to the preparation. Finish by incorporating the rum and crushed walnuts. Mix well then set aside in the fridge for the rest of the preparation.
➔Cut the bananas into slices and arrange them in the bottom of a lightly buttered mold. Cover the slices with lemon juice so that they do not darken.
➔Make the caramel. To do this, pour the powdered sugar and water into a saucepan. Heat over high heat while stirring. When the caramel is golden brown, remove the pan from the heat. Pour it over the banana slices. Cover with cake batter.
➔Bake for 30 minutes (oven preheated to 180°C). Check the baking of the cake with a knife blade: it should come out clean and dry. Let the cake cool before turning it out on a plate.
