Ingredients

Scale
  • 1 3/4 cups all-purpose flour
  • 1 teaspoon baking soda
  • 1/2 teaspoon baking powder
  • 1/2 teaspoon salt
  • 1 teaspoon ground cinnamon
  • 3 large, very ripe bananas, mashed
  • 1/2 cup granulated sugar
  • 1/4 cup packed light brown sugar
  • 1 large egg, lightly beaten
  • 1/2 cup vegetable oil
  • 1 teaspoon vanilla extract
  • 1 cup shredded zucchini, squeezed dry
  • Optional: 1/2 cup chocolate chips or nuts
  • Optional Topping: 2 tablespoons granulated sugar mixed with 1/2 teaspoon cinnamon

Instructions

  1. Preheat your oven to 350°F (175°C). Grease and flour a standard 9×5 inch loaf pan.
  2. In a medium bowl, whisk together the flour, baking soda, baking powder, salt, and cinnamon. Set this dry mixture aside.
  3. In a large bowl, combine the mashed bananas, granulated sugar, brown sugar, egg, vegetable oil, and vanilla extract. Mix these wet ingredients until just combined.
  4. Add the dry ingredients to the wet ingredients. Mix with a spatula until you see no more streaks of flour. Do not overmix; a few lumps are fine.
  5. Gently fold in the squeezed, shredded zucchini and any optional additions like chocolate chips or nuts.
  6. Pour the batter into the prepared loaf pan. If using the optional topping, sprinkle the sugar and cinnamon mixture evenly over the top of the batter.
  7. Bake for 55 to 65 minutes, or until a wooden skewer inserted into the center comes out clean. If the top browns too quickly, loosely tent the pan with foil after 40 minutes.
  8. Let the bread cool in the pan for 10 minutes before carefully turning it out onto a wire rack to cool completely before slicing.

Notes

  • Squeeze excess moisture from the shredded zucchini using a clean kitchen towel or paper towels. This step is key for a non-soggy loaf.
  • For an extra moist banana bread, use bananas that are heavily spotted or almost black.
  • If you want a cream cheese swirl bread variation, prepare a simple cream cheese filling and swirl it into the batter before baking.
