Preheat oven to 350 degrees. Spray a 9 x 5-inch loaf pan with nonstick cooking spray; set aside.
Mix butter and sugar until light and fluffy, using a stand mixer (or hand mixer).
Add eggs and vanilla; mix until fully incorporated.
Stir in bananas by hand.
In a separate bowl, whisk together flour, coconut, salt, baking soda, and baking powder.
Using a spatula, gently fold flour mixture into butter mixture. Do not overmix; there should still be flour visible when you are done.
Fold in nuts, if using. Again, do not overmix.
Transfer batter to loaf pan; top with extra coconut and / or nuts, if desired. Bake for about 45 to 50 minutes, or until a toothpick inserted in the center comes out mostly clean.
Cool bread for at least 20 minutes before slicing. Enjoy!
Notes
To measure flour, lightly spoon it into a dry measuring cup, then use a knife (or something else with a straight edge) to level off the top. Do not scoop the measuring cup into the flour ... you'll end up packing the flour, and the bread will turn out dry.The key to making the BEST quick breads is to avoid overmixing the batter. Always use a spatula to fold (not stir) the wet and dry ingredients together. And don't worry if there's a spot or two of flour showing when you're done. These silicone spatulas are my fave!Make sure to allow your bananas to turn brown before making this bread.Calories are a guideline and can vary depending on how you measure, brands you use, etc. Because the macadamia nuts are optional, they are not included in the calorie count.Check out the information before this recipe card for more tips, variations, and related recipes!
