Preheat your oven to 350°F (175°C). Grease a loaf pan and set aside.
In a large mixing bowl, combine the gluten-free sourdough starter, gluten-free flour, cocoa powder, honey or maple syrup, melted coconut oil or butter, salt, and baking soda. Mix until well combined.
Beat the eggs in a separate bowl, then add them to the batter. Mix until smooth.
If desired, fold in the chocolate chips until evenly distributed throughout the batter.
Pour the batter into the prepared loaf pan and smooth the top with a spatula.
Bake in the preheated oven for 40-45 minutes, or until a toothpick inserted into the center comes out clean.
Once baked, remove the bread from the oven and allow it to cool in the pan for 10-15 minutes before transferring it to a wire rack to cool completely.
