01 - Preheat your oven to 350°F (175°C). Prepare a 9x5-inch loaf pan by greasing and flouring it, or lining it with parchment paper.
02 - In a large mixing bowl, mash the ripe bananas until smooth. Add the lemon juice, melted butter, granulated sugar, room temperature eggs, and vanilla extract. Whisk until thoroughly combined.
03 - In a separate bowl, whisk together the all-purpose flour, baking soda, baking powder, and salt.
04 - Gradually add the dry ingredients to the banana mixture. Stir gently until just combined. Be careful not to overmix.
05 - Fold the unsweetened shredded coconut into the batter until evenly distributed.
06 - Transfer the batter into the prepared loaf pan, ensuring the top is smoothed evenly.
07 - Bake for 50 to 55 minutes, or until a toothpick inserted into the center of the loaf comes out clean.
08 - Allow the loaf to cool in the pan for 10 minutes before transferring it to a wire rack to cool completely before slicing.
