Sourdough starter, warm water, all-purpose flour, cocoa powder, sugar, salt, chocolate chips, olive oil (optional)
Mix all ingredients. Let rise for 10 to 14 hours. Shape gently and rest again. Bake in a Dutch oven at 450°F. Cool before slicing.
Use Dutch-processed cocoa for deeper flavor. Add nuts or dried fruit. Let the loaf cool fully for best texture.
