Preheat oven to 180°C/350°F fan oven and grease a baking tin.
In a mixing bowl mix all dry ingredients. Whisk together eggs, coconut oil, almond milk and maple syrup. Mix with the dry ingredients and fold in grated zucchini and walnuts.
Fill into the prepared baking tin and bake on the middle rack for about 45 minutes.
The bread is ready when a tooth pick inserted comes out clean. Take out and leave to cool in the tin for a couple of minutes. Remove from the baking tin and let cool completely.
