Preheat oven to 350 degrees F. Line a muffin pan with paper liners.
In a large bowl, make the flax eggs by adding the ground flaxseeds and water. Stir and set aside for 5 minutes to thicken.
In a medium bowl, add the flour, baking soda, baking powder, salt, cinnamon, and nutmeg. Whisk until well combined.
In the large bowl with the flax eggs, mash the bananas. Then add the shredded zucchini, coconut sugar, almond milk, avocado oil, and vanilla. Whisk until well combined.
Add the dry ingredients to the wet. Use a spatula to stir until just combined. Don’t over-mix. Fold in chocolate chips.
Fill each muffin tin pretty much to the top to get big muffins. Top with extra chocolate chips if desired. Bake for 20-25 minutes (depends on how big you make your muffins) or until a toothpick inserted in the middle comes out clean. Let it cool in the pan for 10 minutes. Remove and place on a wire rack to cool completely. Enjoy!
Store leftovers in an airtight container on the counter for 3 days. The flavors are even better the next day!
