Preheat your oven to 350°F (175°C). This ensures your bread bakes evenly.
Grease your loaf pan with a little coconut oil or line it with parchment paper for easy removal.
In a large mixing bowl, whisk together the white whole wheat flour, baking powder, baking soda, ground cinnamon, kosher salt, nutmeg, and ground ginger until well combined.
In another bowl, whisk together the honey, melted coconut oil, eggs, buttermilk, and vanilla extract until smooth and creamy.
Pour the wet ingredients into the dry ingredients and stir gently with a spatula until just combined. Be careful not to overmix; a few lumps are fine.
Gently fold in the shredded zucchini and dark chocolate chips, ensuring they are evenly distributed throughout the batter.
Pour the batter into the prepared loaf pan. For an extra touch, sprinkle a few additional chocolate chips and the turbinado sugar on top.
Bake in the preheated oven for 50-60 minutes or until a toothpick inserted in the center comes out clean. Keep an eye on it around the 50-minute mark.
Once baked, remove the bread from the oven and let it cool in the pan for about 10 minutes. Then, transfer it to a cooling rack to cool completely before slicing.
