Preheat your oven to 350°F (175°C) and grease a 9x5-inch loaf pan or line it with parchment paper.
In a large mixing bowl, combine the mashed bananas and melted coconut oil until smooth and creamy.
Add the brown sugar and granulated sugar, mixing until well incorporated.
Stir in the beaten eggs and vanilla extract until fully blended.
Sprinkle the baking soda and salt over the banana mixture, stirring to combine.
Gently fold in the flour, being careful not to overmix; it’s okay if there are a few lumps.
Finally, fold in the chocolate chips and chopped walnuts if using.
Pour the batter into the prepared loaf pan, smoothing out the top with a spatula.
Bake in the preheated oven for 60-65 minutes, or until a toothpick inserted in the center comes out clean.
Once baked, allow the banana bread to cool in the pan for 10 minutes before transferring it to a wire rack to cool completely.
Notes
Slice the banana bread and serve it warm with a drizzle of melted chocolate on top, garnished with a sprinkle of powdered sugar or a few extra chocolate chips for a decorative touch.
