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 (about 1 1/2 cups)
  • 1 cup granulated sugar
  • 1/2 cup packed light brown sugar
  • 2 large eggs
  • 1/2 cup vegetable oil
  • 1 teaspoon vanilla extract
  • 1 1/2 cups shredded zucchini, squeezed dry (about 1 medium zucchini)

Instructions

  1. Preheat your oven to 350°F (175°C). Grease and flour a standard 9×5 inch loaf pan, or line it with parchment paper.
  2. In a large bowl, whisk together the flour, baking soda, baking powder, salt, and cinnamon. This mixes your dry ingredients.
  3. In a separate medium bowl, mix the mashed bananas, granulated sugar, brown sugar, eggs, vegetable oil, and vanilla extract until just combined.
  4. Pour the wet ingredients into the dry ingredients. Mix with a spatula until just combined. Do not overmix; a few streaks of flour are fine.
  5. Gently fold in the squeezed, shredded zucchini until it is evenly distributed throughout the batter.
  6. Pour the batter into your prepared loaf pan.
  7. Bake for 55 to 65 minutes, or until a wooden skewer inserted into the center comes out clean or with moist crumbs attached.
  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 the shredded zucchini firmly in a clean kitchen towel or paper towels to remove excess water. This step is key to preventing a gummy loaf.
  • Using very ripe, spotty bananas adds natural sweetness, which helps reduce the need for extra sugar.
  • If you want a cinnamon swirl, mix 1/4 cup brown sugar with 1 teaspoon cinnamon. Layer half the batter, sprinkle with half the cinnamon mixture, add the rest of the batter, and top with the remaining cinnamon mixture before baking.
