Preheat oven and prep bread pan: First, preheat your oven to 350 degrees. Either grease bread pan with a bit of oil, or line with parchment paper. Then shred your fresh zucchini, if you haven’t already.
Make flax egg: Add ground flax seeds and hot water to a small bowl and mix until well combined, then let sit 5 minutes to thicken.
1 tablespoon ground flax egg, 3 tablespoons hot water
Mix dry ingredients: Sift the flour into a large mixing bowl, then add white granulated sugar, brown granulated sugar, baking soda, baking powder, cinnamon, nutmeg, and salt. Whisk to combine.
2 cups all purpose flour, ⅓ cup white granulated sugar, ⅓ cup light brown sugar, 1 teaspoon baking soda, 1 teasoon baking powder, 1 teaspoon ground cinnamon, ¼ teaspoon nutmeg, ½ teaspoon salt
Add wet ingredients and let sit: Add the shredded zucchini, thickened flax egg, plant-based milk, oil (or applesauce), vanilla extract, and apple cider vinegar to the bowl of dry ingredients and mix to combine. The mixture may seem very dry, but continue to mix until it is as combined as possible and then let the batter sit for 5-10 minutes until the zucchini releases its water. The moisture from the zucchini will help hydrate the ingredients and after sitting you can mix a bit more to make sure the batter is well mixed.
1 cup shredded zucchini, ¼ cup plant-based milk, ½ cup neutral oil, 1 teaspoon vanilla extract, 1 tablespoon apple cider vinegar
Make crumb topping (optional): Add flour, sugar, and cinnamon to a small bowl and mix to combine. Then add melted vegan butter and use your fingers to mix it into the flour mixture to create a crumb-like texture.
⅓ cup all purpose flour, 3 tablespoons granulated sugar, ¼ teaspoon ground cinnamon, 3 tablespoons vegan butter
Bake bread: Add batter to the bread pan and sprinkle with crumb topping (if using). Place pan in the oven and bake 45-50 minutes, or until a toothpick or fork comes clean.
Cool and enjoy: Remove bread and let the pan cool for 10 minutes before removing the bread. Then let the bread cool completely before servings or storing. Then enjoy!
