Follow these easy steps to create your own Hawaiian Banana Bread:

1. Preheat the Oven: Begin by preheating your oven to 350°F (175°C). Grease a 9×5-inch loaf pan.
2. Prepare the Bananas: In a large mixing bowl, mash the ripe bananas until smooth.
3. Mix Butter and Sugar: Add the softened butter and granulated sugar into the bowl with the mashed bananas. Mix thoroughly until well combined.
4. Add Egg and Vanilla: Stir in the beaten egg and vanilla extract, mixing until smooth.
5. Combine Dry Ingredients: In a separate bowl, whisk together the all-purpose flour, baking soda, salt, and optional cinnamon.
6. Combine Wet and Dry Mixtures: Gradually add the dry ingredient mixture to the wet ingredients. Stir until just combined; do not overmix.
7. Add Pineapple and Coconut: Gently fold in the crushed pineapple and shredded coconut. If using, add chopped walnuts at this stage.
8. Transfer to Pan: Pour the batter into the prepared loaf pan and smooth the top with a spatula.
9. Bake: Place the loaf pan in the preheated oven and bake for 50-60 minutes. A toothpick inserted in the center should come out clean.
10. Cool: Once baked, remove the bread from the oven. Allow it to cool in the pan for about 10-15 minutes before transferring it to a wire rack to cool completely.

You are now just steps away from enjoying the delectable Hawaiian Banana Bread!
