Mix the Dough
In a large bowl, whisk together the bread flour and cocoa powder. Add:
✅ 100g sourdough starter
✅ 300g warm water
✅ 50g honey or sugar
✅ 50g softened butter
✅ 8g salt
Mix until a shaggy dough forms. Cover and let it rest for 30 minutes.
Strengthen the Dough
Perform 3-4 sets of stretch and folds, one every 30 minutes over the next 2 hours.
If adding chocolate chips or dried fruit, fold them in during the third stretch and fold.
Bulk Fermentation (6-8 Hours, Room Temp 70-75°F)
Cover the bowl and let the dough rise until puffy and about 50% larger.
If your kitchen is cool, this may take longer.
Shape the Loaf
Gently turn the dough onto a floured surface.
Shape it into a round boule or an oval loaf.
Place it seam-side up in a floured banneton or bowl lined with a towel.
Final Proof (2-3 Hours, Room Temp 70-75°F)
Cover and let it rise again until it passes the poke test—a gentle press should spring back slowly.
Alternative: If baking the next morning, place the shaped dough in the fridge overnight (cold-proof for up to 12 hours).
Preheat & Bake
Preheat oven to 450°F (230°C) with a Dutch oven inside.
Turn the dough onto parchment paper, score the top, and carefully place it in the hot Dutch oven.
Bake covered for 20 minutes, then uncovered for 15-20 minutes until deep brown.
Cool & Enjoy
