Preheat your oven to 350 degrees Fahrenheit. This ensures that your bread will bake evenly and thoroughly.
In a large mixing bowl, mash the bananas until they’re smooth. You can use a fork or a potato masher for this step. Make sure to leave no lumps for an even texture.
Add the coconut palm sugar and vanilla to the mashed bananas. With a hand mixer, blend the ingredients together until well combined. The mixture should be smooth and creamy.
Gradually pour in the water while mixing. This will help to achieve the right consistency of the batter. Continue mixing until everything is incorporated.
In another bowl, combine the whole wheat flour, cocoa powder, baking soda, cinnamon, and baking powder. Stir these dry ingredients together until evenly mixed.
Now, it’s time to combine the wet and dry mixtures. Slowly add the dry ingredients into the banana mixture. Use a fork or spatula to fold the dry mixture into the wet mixture. Be careful not to overmix; you just want everything to come together.
Fold in the vegan chocolate chips and chopped nuts until they are evenly distributed throughout the batter. This adds wonderful texture and flavor to your bread.
Pour the batter into a nonstick loaf pan, ensuring that it's evenly spread out. You want a nice, even loaf when it bakes.
Place the loaf pan in the preheated oven and bake for 55 to 65 minutes. Start checking for doneness around the 50-minute mark. A cake tester inserted into the center should come out clean when it’s done.
Once baked, remove the loaf from the oven and let it cool in the pan for about 10 minutes. Then, transfer it to a wire rack to cool completely before slicing. This cooling time helps to set the structure of the bread, ensuring clean slices.
