Think of this as a marble cake filled with sweet banana and Nutella deliciousness.
1 1/4 cup self rising flour
1/2 cup brown sugar
Vanilla Extract, to taste
10 tablespoons butter
1/3 cup nutella
Preheat the oven at 350°F (180°C). Mix the butter with the
Sugar, then add the egg. Crush the bananas and add them to the mixture with the vanilla extract as well.
Add the flour and mix.
Pour half the amount of the mixture to the mold, then half the amount of nutella over the mixture and stir to incorporate. Add the mixture's remainings and do the same with the nutella.
Bake in the oven for 30/40 minutes.
