Preheat the oven to 350°F. Line or grease a standard size loaf pan and set aside.
In a large bowl, whisk together the eggs, milk, pure maple syrup and vanilla extract.
To the same bowl, add the dry ingredients (almond flour, brown rice flour, coconut sugar, baking soda, cinnamon and salt). Stir until well combined.
Lastly, fold in the shredded zucchini and chocolate chips.
Transfer the batter into the loaf pan. Bake in the oven for 45-60 minutes, or until the center is firm to the touch. Allow to cool for 15-20 minutes before serving.
Store in an airtight container in the refrigerator for up to 4 days. Please note that when the bread is cold, it changes the texture. You may want to let it sit out at room temperature for about 30 minutes before eating after refrigeration.
