This recipe for sourdough chocolate zucchini bread combines the tangy essence of sourdough with the richness of chocolate, creating a moist and decadent treat that’s perfect for any occasion.
Preheat oven to 350 degrees (175 degrees Celsius). Grease and flour 9x5 loaf pan or line with parchment paper.
In a mixing bowl, combine the all-purpose flour, cocoa powder, baking powder, baking soda, salt, and cinnamon. Whisk them together until well combined. If desired, sift the dry ingredients to ensure a smooth mixture.
In a separate large bowl, whisk together the melted coconut oil with the brown sugar and milk until smooth. Add the eggs one at a time, beating well after each addition. Stir in the vanilla extract and sourdough starter until fully combined.
Gradually add the dry ingredients to the wet mixture, stirring until just combined. Be careful not to overmix; a few lumps are okay. Fold in the grated zucchini, walnuts, and chocolate chips, if using, until evenly distributed throughout the batter.
Pour the batter into the prepared loaf pan. Smooth the top with a spatula. Bake in the preheated oven for 55-60 minutes or until a toothpick inserted into the center comes out clean or with a few moist crumbs attached.
Allow the bread to cool in the pan for about 10-15 minutes, then carefully transfer it to a wire rack to cool completely. Once cooled, slice and enjoy your delightful sourdough chocolate zucchini bread!
