Preheat your oven to 176℃ / 350°F. Grease a 9x5-inch loaf pan or line it with parchment paper.
In a large mixing bowl, combine the mashed bananas, eggs, honey, melted coconut oil, and vanilla extract. Mix until well combined.
In a separate bowl, whisk together the gluten-free flour, cocoa powder, baking soda, and salt.
Gradually add the dry ingredients to the wet ingredients, stirring until just combined.
Gently fold in the dark chocolate chips or chopped dark chocolate.
Pour the batter into the prepared loaf pan and spread it out evenly.
Bake in the preheated oven for 50-60 minutes, or until a toothpick inserted into the center comes out clean.
Remove the banana bread from the oven and allow it to cool in the pan for 10 minutes before transferring it to a wire rack to cool completely.
Once cooled, slice and serve. Enjoy your delicious Gluten-Free Chocolate Banana Bread!
