Step 1

Preheat your oven to 180 degrees C (fan).

Step 2

Cream the butter together with the sugar, and then break in the eggs and mix well.

Step 3

Stir in the bananas.

Step 4

Add the flour, baking powder and salt. Stir till well combined but don't over mix.

Step 5

Put the mixture in a greased cake tin. I used a deep 8 inch tin.

Step 6

Drop in the spoons of Nutella and use a knife to marble it in the cake batter.

Step 7

Bake for around 45-50 mins or until a skewer comes away clean. If it browns too much on top, cover the cake with foil for the last ten minutes.
