In a large bowl, sift the flour, baking powder, baking soda, salt, and cinnamon together. Set aside. Whisk the coconut oil, honey, maple syrup, yogurt1, eggs, milk2, and vanilla in a medium bowl until combined. Pour the wet ingredients into the dry ingredients and fold together with a rubber spatula or wooden spoon until combined. Avoid overmixing. Fold in the zucchini and any add-ins of your choice.
