Banana Marble Loaf

Directions

1. 1
   Pre-heat the oven to 180 degrees Celsius and grease a loaf pan with butter and line with parchment paper.
2. 2
   Add the peeled banana to a large bowl. Using an immersion blender, puree the banana until smooth. Whisk in the eggs one by one, followed by the melted butter and the lemon juice.
3. 3
   In a separate bowl, whisk together the baking soda, salt, sugar and flour. Add the dry ingredients to the wet ingredients and stir to combine.
4. 4
   Divide the batter in two. Add the cacao and espresso to one half of the batter and whisk until just combined.
5. 5
   Fill the batter into the prepared loaf pan alternating between the plain batter and the cacao batter. Once finished, use a fork to gently swirl the two batters together - this is what will give the finished cake a marbled pattern.
6. 6
   Bake the loaf for about 1h or until a wooden skewer inserted into the centre of the loaf comes out clean.
