Ingredients

Scale

For the Lemon Zucchini Bread:

  • 1 cup whole wheat pastry flour* (or regular whole wheat flour)
  • 1 cup all-purpose flour
  • 1 teaspoon baking powder
  • 1/2 teaspoon baking soda
  • 1/2 teaspoon salt
  • 1/2 teaspoon ground cinnamon
  • Zest of 2 lemons
  • 1/2 cup (1 stick) unsalted butter, melted and cooled slightly
  • 3/4 cup granulated sugar
  • 1/4 cup packed light brown sugar
  • 2 large eggs, room temperature
  • 2 teaspoons vanilla extract
  • 1/4 cup unsweetened vanilla almond milk* (or other milk), room temperature
  • 1/3 cup sour cream, room temperature
  • 1 1/2 cups grated zucchini (do not squeeze dry)
  • Butter or coconut oil, for greasing pan

For the Vanilla Bean Cream Cheese Glaze:

  • 1/4 cup + 2 tablespoons (approx. 50g) powdered sugar (confectioners’ sugar), sifted
  • 2 tablespoons whipped cream cheese (or regular block cream cheese, softened)
  • 12 tablespoons milk
  • 1 teaspoon vanilla extract
  • Seeds scraped from 1/2 vanilla bean (or use 1/2 tsp vanilla bean paste)

Instructions

1. Make the Bread:

  • Preheat and Prep: Preheat oven to 350°F (175°C). Grease and flour a 9×5 inch loaf pan. Lining the bottom with parchment paper is optional but helps with removal. Set aside.
  • Combine Dry Ingredients: In a medium bowl, whisk together the whole wheat pastry flour, all-purpose flour, baking powder, baking soda, salt, cinnamon, and lemon zest. Set aside.
  • Combine Wet Ingredients: In a separate large bowl, whisk together the melted (and slightly cooled) butter, granulated sugar, and brown sugar until smooth. Whisk in the room-temperature eggs one at a time, then whisk in the vanilla extract. Whisk in the room-temperature milk and sour cream until thoroughly combined.
  • Fold in Zucchini: Gently fold the grated zucchini into the wet ingredients.
  • Combine Wet and Dry: Gradually add the dry ingredients to the wet ingredients, stirring with a rubber spatula until just combined. Be careful not to overmix.  
  • Bake: Pour the batter into the prepared loaf pan and spread evenly. Bake for 45-50 minutes, or until the edges are golden brown, the top is firm, and a wooden toothpick inserted into the center comes out clean.
  • Cool: Let the bread cool in the pan on a wire rack for at least 30 minutes before carefully removing it from the pan. Let it cool completely on the wire rack before glazing.

2. Make the Glaze:

  • In a small bowl, whisk together the sifted powdered sugar, whipped (or softened) cream cheese, 1 tablespoon of milk, vanilla extract, and vanilla bean seeds until smooth.
  • Add more milk, 1 teaspoon at a time, until the glaze reaches your desired drizzling consistency.

3. Glaze and Serve:

  • Once the bread is completely cool, pour or drizzle the glaze over the top.
  • Slice and serve for breakfast, a snack, or dessert!

Notes

  • Flour: Whole wheat pastry flour creates a tenderer crumb than regular whole wheat flour. You can substitute regular whole wheat or use all all-purpose flour if preferred. Measure flour correctly using the spoon & level method or by weight.
  • Zucchini: Use standard green zucchini. Grate it using the large holes of a box grater. Do not squeeze the moisture out for this recipe.
  • Room Temperature Ingredients: Using room temperature eggs, milk, and sour cream helps the batter mix evenly.
  • Do Not Overmix: Mix the batter only until the flour is just incorporated to keep the bread tender.
  • Cooling: Ensure the bread is completely cool before glazing, otherwise the glaze will melt and slide off.
  • Glaze: Whipped cream cheese blends easily. If using block cream cheese, make sure it’s very soft. Adjust milk for desired thickness. Vanilla bean paste can be substituted for seeds.
  • Storage: Store glazed bread covered at room temperature for 2 days or in the refrigerator for up to 5 days.
