In a bowl mash 4 ripe bananas.
Add in the melted butter, eggs, light brown sugar, milk and vanilla extract. Whisk very well. Add in the cinnamon, salt, and rushed walnuts.
Place remaining dry ingredients in another bowl and mix well. Pour in all the dry ingredients into the bowl with liquid ingredients and mix to combine well.
Spray a non-stick 9x 5 pan with some baking spray and pour in the batter. Add the melted Nutella on top and swirl it around with a wooden skewer or table knife.
Bake in a pre-heated 350 degree oven for 40-45 minutes or until a wood skewer is inserted and comes out clean. Remove and let it cool down before serving.
