Preheat your oven to 350°F. Line it with parchment paper.
In a large mixing bowl, whisk together the flour, baking soda, baking powder, salt, cinnamon, and nutmeg until well combined.
In another bowl, whisk together the sugar, melted butter, eggs, and vanilla essence until the mixture is smooth.
Add the wet mix to the dry mix and whisk to combine.
Gently fold in the shredded zucchini and the nuts.
Pour the batter into the prepared loaf pan and spread it out evenly. Bake in the preheated oven for about 35 – 45 minutes or until a toothpick inserted into the center of the bread comes out clean.
