Preheat oven to 350 F and coat a 9×5 inch loaf pan with coconut oil or oil of choice
Make oat flour using a powerful blender, I used the Nutribullet – measure 1 cup after oats have been grounded into flour.
Combine flours, hemp hearts, baking powder, baking soda, cinnamon, and salt in a bowl.
In a separate bowl whisk eggs, maple syrup, milk, oil and vanilla in a large bowl.
Use the Nutribullet to shred zucchini and add shredded zucchini to the wet ingredients.
Stir in the dry ingredients into the wet ingredients and gently fold until everything is combined. Add in chocolate chips and walnuts (if using).
Transfer the batter into the loaf pan, sprinkle with 1 tsp of rolled oats. Bake for 50-55 minutes. Or until a toothpick inserted in the center comes out clean.
