Spoon the mixture into the prepared tin and spread mixture evenly. Pop into the oven and cook for about 40 minutes or until golden brown. To check that the banana loaf is cooked all the way through put a fine skewer through the centre. If it comes out clean then the banana loaf is cooked.
Leave to cool for a few minutes before using a palette knife to gently loosen the cake out of the tin. Remove the baking paper and pop onto a wire rack to cool completely. Once cooled, cut into slices and serve.
