Preheat Your Oven Begin by preheating your oven to 350°F (175°C). Grease and flour a 9x5-inch loaf pan, or line it with parchment paper for easy removal.
Mix the Dry Ingredients In a large mixing bowl, whisk together the flour, sugar, baking soda, and salt. This ensures that the leavening agents and sugar are evenly distributed throughout the batter.
Prepare the Wet Ingredients In another bowl, combine the mashed bananas, vanilla extract, eggs, and coconut milk. Stir until the mixture is smooth and well blended.
Combine and Fold Pour the wet ingredients into the dry ingredients. Gently fold them together until just combined. Be careful not to overmix; you want to keep the bread light and fluffy.
Add the Walnuts Fold in the chopped walnuts, ensuring they are evenly distributed throughout the batter.
Pour and Top Pour the batter into the prepared loaf pan. Sprinkle a handful of extra chopped walnuts on top for a crunchy finish.
Bake to Perfection Place the pan in the preheated oven and bake for about 1 hour, or until a toothpick inserted into the center comes out clean. The top should be golden brown, and your kitchen will smell heavenly.
Cool and Enjoy Allow the bread to cool in the pan for about 10 minutes before transferring it to a wire rack to cool completely. Slice and serve with a pat of butter or enjoy it as is.
