Ingredients

  • 15g unsalted butter
  • 70ml vegetable oil
  • 160g light brown sugar
  • 2 eggs room temperature
  • 1 teaspoon vanilla extract
  • 80ml soured cream fresh
  • ½ teaspoon salt
  • 160g self-raising flour
  • 1 large banana
  • 18g cocoa powder

Instructions

  • Preheat the oven to gas mark 3/325oF/160oC and line a 2lb/900g loaf tin with parchment paper. Add the butter to a microwaveable bowl and melt for 35 seconds or until fully melted. 
  • In a medium bowl, whisk together the melted butter, vegetable oil and sugar.  Mix in the eggs then the vanilla extract followed by the sour cream. Fold in the flour then pour half the batter into another bowl. 
  • Mash the banana with a fork then add it to one of the bowls and fold it into the batter. To the other bowl, add the cocoa powder and mix until smooth. 
  • Add a dollop of vanilla batter to the loaf pan then add some chocolate batter. Place the batter randomly in the tin to create a marble effect. Repeat this process alternating between both batters until all the batter is used. Bake the loaf in the centre of the oven for 60 minutes.  The time may vary so check every 5 minutes once it has baked for 50 minutes.
  • Remove the loaf from the oven and allow to cool in the tin for 40 minutes then remove the loaf cake from the pan and place directly on the wire rack to completely cool before slicing.
