This easy and delicious double chocolate sourdough banana bread layers 2 types of chocolate into the easiest banana bread recipe using your sourdough starter to create your new favorite chocolate indulgence!
Preheat oven to 180C/350F. Grease a loaf pan with butter and set aside.
Mash the overripe bananas with the back of a fork until they are fairly smooth (a few lumps is fine).
Now add the eggs and vanilla extract to the bananas and whisk through until well combined, followed by the melted butter.
Now add the sourdough starter to the egg mixture and mix throughly, along with the brown and white sugars. It should resemble runny caramel at this point.
In a separate bowl, mix the all purpose flour, baking powder, salt, cocoa powder and chocolate chips and ensure that everything is mixed thoroughly.
Now add the dry ingredients to the wet ingredients and stir until just combined.
Pour the mixture into the pan you prepared earlier.
Bake at 180C/350F for around 1 hour. Baking time will depend on the size of your pan and your oven. The banana bread is cooked when a skewer is inserted and comes out clean.
Allow to cool for 30 minutes before removing from the pan and transferring to a wire cooling rack to cool completely. I recommend cooling fully for easier slicing.
