Begin by preheating your oven to 350°F (175°C). Prepare a 9x5 inch loaf pan by greasing it lightly or using parchment paper for easy removal of the bread after baking.
In a large mixing bowl, take the mashed bananas and combine them with the melted coconut oil, stirring well to create a smooth mixture.
Add the packed brown sugar to the banana and oil mixture, mixing thoroughly until well incorporated.
Incorporate the beaten egg and vanilla extract into the mixture, stirring until everything is completely combined.
Evenly sprinkle the baking soda and a pinch of salt over the mixture. Stir gently just until these ingredients are blended in.
Slowly add the all-purpose flour to the bowl, mixing softly until there are no visible dry spots in the batter. Be cautious not to over-mix, as this can affect the texture of the bread.
Gently fold in the chocolate chips and optional chopped walnuts, ensuring they are evenly distributed throughout the batter.
Transfer the batter into the prepared loaf pan and smooth the top with a spatula. Add extra chocolate chips on top for a delightful touch of richness.
Place the loaf pan in the preheated oven and bake for 55-60 minutes, or until a toothpick inserted in the center comes out clean, indicating it is fully baked.
Once baked, remove the bread from the oven and allow it to cool in the pan for about 10 minutes. Carefully transfer it to a wire rack to cool completely before slicing.
Notes
Serve warm with butter or vanilla ice cream for an indulgent treat.
