In a small bowl, mix 1 tablespoon of flaxseed meal with 3 tablespoons of water. Stir well and let it sit for about 10 minutes until it thickens and becomes gelatinous.
In a large mixing bowl, mash the ripe bananas until smooth. You should have about 1 ½ cups of mashed bananas.
Add the melted coconut oil, coconut sugar, vanilla extract, and the prepared flax egg to the mashed bananas. Stir until well combined.
In another bowl, whisk together the gluten-free all-purpose baking flour, Dutch process cocoa, baking soda, and sea salt.
Gradually add the dry ingredient mixture into the wet ingredients, stirring gently until just combined. Be careful not to overmix.
Gently fold in the vegan chocolate chips, ensuring they are evenly distributed throughout the batter.
Grease a loaf pan or line it with parchment paper for easy removal. Pour the batter into the prepared pan, smoothing the top with a spatula.
Bake in the preheated oven for 50-60 minutes, or until a toothpick inserted into the center comes out clean. If the top begins to brown too quickly, cover it with foil for the remaining baking time.
Once baked, remove the banana bread 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. Enjoy your Chocolate Gluten Free and Vegan Banana Bread warm or at room temperature!
