This recipe makes a very moist quick bread using ripe bananas and grated zucchini. It is simple to prepare in one bowl.

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
  • 1/2 cup unsalted butter, melted
  • 3/4 cup granulated sugar
  • 1/4 cup packed light brown sugar
  • 2 large eggs, lightly beaten
  • 1 teaspoon vanilla extract
  • 1 cup mashed ripe bananas (about 3 medium)
  • 1 cup grated zucchini, squeezed dry

Instructions

  1. Preheat your oven to 350 degrees F (175 degrees C). Grease and flour a 9×5 inch loaf pan.
  2. In a medium bowl, whisk together the flour, baking soda, baking powder, salt, and cinnamon. Set this mixture aside.
  3. In a large bowl, whisk the melted butter, granulated sugar, and brown sugar until combined.
  4. Whisk in the eggs and vanilla extract until smooth.
  5. Stir in the mashed bananas until just mixed.
  6. Add the squeezed, grated zucchini to the wet ingredients and mix gently.
  7. Add the dry ingredients to the wet ingredients. Mix with a spatula until just combined. Do not overmix the batter.
  8. Pour the batter into the prepared loaf pan.
  9. Bake for 55 to 65 minutes, or until a wooden skewer inserted into the center comes out clean.
  10. Let the bread cool in the pan for 10 minutes before turning it out onto a wire rack to cool completely.

Notes

  • Squeeze excess water from the grated zucchini using a clean kitchen towel or paper towels. This prevents a soggy loaf.
  • Use very ripe, spotty bananas for the best flavor and moisture.
  • You can substitute half the all-purpose flour with whole wheat flour for a slightly heartier texture.
