Preheat oven to 350° F and grease a 9″x5″ loaf pan or line with parchment paper.
In a medium bowl, stir together flour, baking powder, baking soda, salt, cinnamon and nutmeg.
In a large bowl, whisk together eggs, coconut sugar, oil, mashed bananas, grated zucchini and vanilla.
Add dry ingredients into the bowl with the wet ingredients and stir together until just combined, making sure to not over-mix!
Gently fold in the chocolate chips.
Pour the batter into the prepared loaf pan and top with extra chocolate chips.
Bake for 50-60 minutes, until a toothpick inserted in the middle comes out clean, covering the pan with foil around the 30 minute mark to prevent the top from browning too much.
Let cool in pan for 10-15 minutes, then remove and let cool completely on a wire rack before slicing.
