Preheat your oven to 350°F (175°C).
In a mixing bowl, mash the ripe bananas until smooth.
Stir in the melted coconut oil until well combined.
Add the maple syrup and vanilla extract, mixing thoroughly.
Sprinkle the baking soda and salt over the mixture, stirring to incorporate.
Gradually add the all-purpose flour, mixing just until combined.
If desired, fold in nuts or chocolate chips.
Pour the batter into a greased loaf pan.
Bake for 50-60 minutes, or until a toothpick comes out clean.
Allow the bread to cool in the pan for 10 minutes before transferring to a wire rack.
