Equipment

  • Loaf pan
  • Mixing Bowls
  • Whisk or electric mixer

Ingredients
  

For the Banana Bread Batter

  • 3 ripe bananas Mashed
  • 120 g butter Melted
  • 150 g sugar
  • 2 eggs
  • 1 tsp vanilla extract
  • 200 g all-purpose flour
  • 1 tsp baking soda

For the Chocolate Swirl

  • 30 g cocoa powder Added to a portion of the batter

Instructions
 

  • Preheat your oven to 175°C (350°F). Grease and flour a loaf pan.
  • Prepare the standard banana bread batter by mixing the mashed bananas, melted butter, sugar, eggs, and vanilla. Mix in the flour and baking soda until just combined.
  • Remove about one-third of the plain batter and place it in a separate small bowl. Whisk the cocoa powder into this smaller portion until fully incorporated, creating the chocolate batter.
  • Alternate spooning the plain batter and the chocolate batter into your prepared loaf pan. Do not mix them completely.
  • Take a knife and gently swirl it through the batters in the pan a few times to create the marbled effect. Do not over-swirl, or the colors will blend too much.
  • Bake for 55 minutes, or until a toothpick inserted into the center comes out clean.
  • Let the bread cool in the pan for 10 minutes before transferring it to a wire rack to cool completely.

Notes

Watching the chocolate swirl through the banana batter felt like painting with food — every loaf turns out slightly different, and that’s part of the magic. If you prefer a stronger chocolate flavor, you can increase the cocoa powder slightly.
