Ingredients

Scale

For the Bread:

  • 2 medium zucchinis (about 2 cups grated, drained)
  • 1 ½ cups all-purpose flour
  • 1 tsp baking powder
  • ½ tsp baking soda
  • ½ tsp salt
  • 1 tsp ground cinnamon
  • ½ cup granulated sugar
  • ½ cup brown sugar, packed
  • 2 large eggs
  • ⅓ cup vegetable oil (or melted butter)
  • 1 tsp vanilla extract

For the Cinnamon Swirl:

  • ⅓ cup brown sugar, packed
  • 2 tsp ground cinnamon
  • 1 tbsp melted butter

For the Glaze (optional but recommended):

  • ½ cup powdered sugar
  • 12 tbsp milk
  • ½ tsp vanilla extract

Instructions

  1. Prepare the Zucchini: Grate the zucchinis using a coarse grater, then wrap them in a clean kitchen towel or cheesecloth and squeeze out as much excess moisture as possible. This is important to prevent soggy bread. Set aside the drained zucchini.
  2. Preheat the Oven: Preheat your oven to 350°F (175°C). Grease and flour a 9×5-inch loaf pan or line it with parchment paper for easier removal later.
  3. Mix the Dry Ingredients: In a medium bowl, whisk together the all-purpose flour, baking powder, baking soda, salt, and ground cinnamon until evenly combined. Set aside.
  4. Mix the Wet Ingredients: In a large mixing bowl, beat the eggs with granulated sugar and brown sugar until well combined. Add vegetable oil and vanilla extract, mixing until smooth.
  5. Combine the Zucchini and Dry Ingredients: Gently fold the drained grated zucchini into the wet mixture. Gradually add the dry ingredients, stirring carefully just until combined to avoid overmixing, which could make the bread dense.
  6. Make the Cinnamon Swirl: In a small bowl, mix the brown sugar, ground cinnamon, and melted butter until crumbly and evenly combined.
  7. Layer the Batter and Cinnamon Swirl: Pour half of the batter into the prepared loaf pan. Evenly sprinkle half of the cinnamon mixture over the batter. Pour the remaining batter over it, then sprinkle the rest of the cinnamon mixture on top. Use a knife or skewer to gently swirl the cinnamon into the batter creating a marbled effect.
  8. Bake: Place the loaf pan in the preheated oven and bake for 50-60 minutes. Test doneness by inserting a toothpick into the center; it should come out clean or with a few moist crumbs.
  9. Cool: Allow the bread to cool in the pan for 15 minutes, then remove it from the pan and transfer to a wire rack to cool completely to prevent sogginess.
  10. Make the Glaze: If desired, whisk together powdered sugar, milk, and vanilla extract until smooth. Adjust milk quantity to achieve a drizzling consistency.
  11. Glaze the Bread: Once the bread is fully cooled, drizzle the glaze over the top and let it set for a few minutes before slicing and serving.

Notes

  • You can use frozen zucchini, but be sure it is fully thawed and excess water is squeezed out to keep bread from becoming too wet.
  • If you don’t have brown sugar, substitute with granulated sugar and add a teaspoon of molasses to mimic the flavor.
  • Store leftover zucchini bread in an airtight container at room temperature for up to 3 days or freeze tightly wrapped for up to 3 months. Thaw completely before serving.
  • The glaze is optional but recommended for added sweetness and moisture; you can omit it for a less sweet bread.
