Description

Got a couple of overripe bananas sitting in your fruit bowl? Don’t toss them! Turn them into this Chocolate Marbled Banana Loaf—a moist, rich treat that combines the sweetness of bananas with a swirl of chocolate. Perfect for a cozy coffee break or an afternoon snack, and the marbled effect is easier than you think!


Ingredients

Units Scale
  • 175 g all purpose flour
  • 60 ml vegetable oil
  • 60 g light brown sugar
  • 30 g cocoa powder
  • 2 eggs
  • 1 tsp baking powder
  • 1/4 tsp salt
  • 1/4 tsp baking soda
  • 130 g Greek yoghurt
  • 65 ml milk (hot)
  • 2 tsp vanilla extract
  • 2 large bananas (overripe, mashed)
  • 30 g dark chocolate chips

Instructions

  1. Preheat your oven to 175°C (350°F). Line a non-stick loaf tin with a strip of parchment paper, leaving some overhang on the ends for easy lifting.  Otherwise, grease and line your pan with parchment paper.
  2. In a small bowl, mix the cocoa powder with hot milk until smooth and lump-free. Set aside to cool.
  3. Peel the bananas (from the bottom for easier peeling), then mash them until mostly smooth, leaving a few small lumps for texture.
  4. In a large mixing bowl, combine the brown sugar and vegetable oil, stirring until well combined. Add the Greek yoghurt, mashed bananas, and vanilla extract, mixing until smooth.
  5. Add the eggs, one at a time, whisking well after each addition until fully incorporated.
  6. Sift in the flour, baking powder, baking soda, and salt. Use a silicone spatula to gently fold the dry ingredients into the wet, scraping down the sides and bottom as you go. Be careful not to overmix – just mix until you no longer see dry flour.
  7. Divide the batter into two portions. Mix the cooled cocoa mixture into one portion until well combined.
  8. Scoop the plain and chocolate batters alternately into the prepared loaf tin. Use a skewer or knife to gently swirl for a marbled effect.
  9. Sprinkle chocolate chips on top for extra chocolatey goodness (optional).
  10. Bake in the preheated oven for 48 – 53 minutes or until a skewer inserted into the centre comes out clean.
  11. Let the cake sit in the pan for about 15 minutes. Once cool enough to handle, lift it out using the parchment paper and transfer to a wire rack. Cool for another 15 minutes if you want to enjoy it warm, or completely before slicing.
  12. Slice and enjoy your rich, chocolatey, and perfectly moist marbled banana loaf!
