This Chocolate Sourdough Focaccia is a stunning twist on a classic Italian bread, rich, slightly sweet, and deeply chocolatey. The combination of dark chocolate, cocoa, and sourdough creates a moist, chewy texture with a complex flavor profile.
In a large mixing bowl, combine sourdough starter, warm water, and honey. Stir until dissolved.
In another bowl, whisk together bread flour and cocoa powder, then gradually add to the wet mixture. Stir with a wooden spoon until a rough dough forms.
Cover and let rest for 30 minutes to allow hydration.
Sprinkle salt evenly over the dough, then perform a stretch-and-fold technique 3-4 times. Repeat every 30 minutes for 3 hours.
Gently fold in chopped dark chocolate and hazelnuts until evenly distributed.
Transfer dough to a lightly oiled bowl, cover, and ferment at room temperature for 6–8 hours or until doubled in size.
Grease a 9×13-inch baking pan with olive oil. Transfer dough to the pan and stretch it to fit.
Drizzle olive oil over the surface, cover, and proof for 1-2 hours until slightly puffy.
Preheat oven to 200°C (400°F). Dimple the dough with your fingers before baking.
Bake for 25-30 minutes, until golden and crisp on top with melted chocolate pockets.
Cool in the pan for 10-15 minutes before transferring to a wire rack.
Slice and serve warm for a gooey texture or at room temperature for a firm, rich crumb.
