Preheat the oven to 350°F and grease a 9×5 loaf pan or line it with parchment paper.
In a large bowl, whisk together the whole wheat pastry flour, baking soda, cinnamon, nutmeg, and salt. Set aside.
In a separate bowl, whisk together the eggs, maple syrup, Greek yogurt, almond milk, melted coconut oil, vanilla extract, and shredded zucchini until smooth and fully combined.
Gently fold the wet ingredients into the dry ingredients using a spatula. Mix until just combined, being careful not to over-mix.
Pour the batter into the prepared loaf pan, spreading it evenly.
Bake for 50–60 minutes, or until a toothpick inserted into the center comes out clean.
Allow the bread to cool in the pan for 10 minutes, then carefully invert it onto a wire rack to cool completely.
Slice and enjoy!
