  • Oven


  • 1 large zucchini shredded
  • 3 ripe bananas mashed
  • 6 tablespoons unsalted butter melted
  • ¾ cup granulated sugar
  • 1 teaspoon pure vanilla extract
  • 1 large egg
  • 1 ½ cups all purpose flour
  • 1 teaspoon baking soda
  • ¼ teaspoon ground cinnamon
  • pinch of salt

For the Icing

  • 2 tablespoon milk
  • 1 teaspoon pure vanilla extract
  • 1 cup powdered sugar


  • Preheat oven to 350˚F.
  • Line a 9x13 loaf pan with parchment paper; lightly spray with cooking spray and set aside.
  • Shred zucchini using the large holes on a cheese grater.
  • Transfer shredded zucchini to a kitchen towel; close the towel around the zucchini and squeeze out as much liquid as possible. Set aside.
  • Mash bananas in a large mixing bowl.
  • To the bananas, stir in melted butter, sugar and vanilla.
  • Add egg and stir until incorporated.
  • Add in the flour, baking soda, cinnamon and salt; gently stir until incorporated.
  • Fold in the shredded zucchini.
  • Pour batter into prepared loaf pan.
  • Bake for 45 to 55 minutes, or until a toothpick inserted in the center of the loaf comes out clean.
  • Remove from oven and set the loaf pan over a wire rack; cool for 1 hour.
  • Remove bread from the loaf pan and let stand on wire rack until completely cooled.
  • In the meantime, prepare the icing by combining the milk, vanilla and powdered sugar in a mixing bowl or a large glass measuring cup. Whisk the ingredients until completely blended.
    If you want a thicker icing, add more sugar. If you want a thinner consistency, add a little more milk.
  • Drizzle icing over cooled loaf and let stand until icing is set.
  • Cut, serve, and enjoy!
