Adjust the oven rack to the lower third position and then preheat your oven to 350°F (180° C). This helps prevent the top of the banana bread from browning too much. Then, grease your 9"x 5" loaf pan.
In a large mixing bowl, combine flour, baking powder, baking soda, salt, and cinnamon. Mix with a wooden spoon or whisk so that the ingredients are evenly combined. Set aside.
In a separate medium bowl, add the sugar, oil, vanilla extract, and eggs. Whisk until combined. Then, add the mashed bananas and whisk.
Pour the wet ingredients into the large bowl of dry ingredients. Using a spatula, fold the wet ingredients into the dry ingredients until no flour pockets remain. Do not overmix.
Fold in the macadamia nuts, if using.
Pour and spread the batter into the prepared loaf pan. Bake for 55-65 minutes. The bread is done when a toothpick inserted into the center comes out clean with just a few small moist crumbs.

Pan Size: In this recipe, I use a 9x5-inch Loaf Pan. You can use different pans but will need to adjust bake time accordingly.
Macadamia Nuts: These are optional but highly recommended. You can use nuts of your choice. You can also add chocolate chips.
Baking Time: Baking time is dependent on the oven. This recipe takes around 55-65 minutes. Make sure to use the toothpick test to check if your banana bread is done to prevent a sunken middle.
Toothpick Test: your banana bread is ready when you insert a toothpick into the center and there are a few crumbs on it. If the toothpick has wet batter, it still needs to bake for longer. Make sure not to bake for longer than needed or else you won’t have moist banana bread.
