Preheat & Prep: Preheat your oven to 350°F (175°C) and grease a loaf pan.
Mash & Grate: In a large mixing bowl, mash the bananas. Grate the zucchini, then use a clean kitchen towel to squeeze out excess moisture.
Make Flax Egg: Mix 1 tbsp ground flaxseed with 3 tbsp water, then let it sit for 5 minutes.
Mix Wet Ingredients: Stir in the zucchini, flaxseed egg, maple syrup, coconut oil, and vanilla extract until well combined.
Combine Dry Ingredients: In a different bowl, combine the flour, baking powder, baking soda, cinnamon, and salt by whisking them together.
Mix Batter: Gradually fold the dry ingredients into the wet mixture. Stir gently until just combined. (Don’t overmix, or your bread will be dense!)
Fold in Add-ins: If you’re using chopped nuts, chocolate chips, or raisins, gently fold them into the batter.
Bake: Transfer the batter to the greased loaf pan and bake for 50-60 minutes, or until a toothpick inserted into the center comes clean.
Cool & Serve: Allow the bread to cool in the pan for 10 minutes, then move it to a wire rack to cool fully before slicing.
