Preheat the oven to 365 deg F (190 C), line a loaf pan with parchment or grease well. Mix non dairy milk and chia seeds in a large bowl and let sit for 10 mins. Then whisk in the rest of the wet ingredients until well combined.
Fold in the zucchini. Add the dry ingredients (start with 1.25 cups flour if using more whole grain flour, and more a tbsp at a time), and mix to make a thick muffin like batter. Fold in the chocolate chips (and 1/4 cup chopped nuts if using). ( If omitting the chia seeds from the wet, you will need a bit more flour to get the thick batter).
Pour into prepared pan. Sprinkle 1 tbsp chocolate chips on top.
Bake at 365 degrees F (190 deg C) for 55 to 65 minutes or until a toothpick comes out almost clean from the center. (baking time will depend on the moisture content of the zucchini and the batter) . For a gluten-free bread, see GF Zucchini Loaf
