- 350g water
- 100g active sourdough starter
- 10g salt
Chocolate Dough Portion
- 15g unsweetened cocoa powder
- 10g warm water
Optional Add-Ins
- 50g dark chocolate chips
- 30g chopped chocolate

Equipment Needed

- Kitchen scale
- Dough scraper
- Banneton basket
- Dutch oven
- Sharp bread lame or razor
- Clean kitchen towel
Understanding the Ingredients
Bread Flour
Bread flour provides:
- Strong gluten structure
- Excellent chew
- Better rise
High-protein flour is ideal for artisan sourdough baking.
Active Sourdough Starter
A healthy starter should:
- Double in size after feeding
- Be bubbly
- Smell pleasantly tangy
The starter serves as the sole leavening agent.
Cocoa Powder
Use:
- Unsweetened cocoa powder
- Dutch-process cocoa (optional)
The cocoa creates deep chocolate flavor and rich color.
Preparing Your Starter
For best results:
Feed your starter approximately 4–6 hours before mixing the dough.
It should be:
- Active
- Bubbly
- At peak rise
This ensures strong fermentation and good oven spring.
Step 1: Mix the Main Dough
In a large bowl combine:
- Water
- Active starter
Stir until the starter dissolves.
Add:
- Bread flour
Mix until no dry flour remains.
The dough will appear shaggy.
Cover and rest for:
30 minutes
This stage is called autolyse.
Why Autolyse Matters
Autolyse helps:
- Hydrate flour
- Improve gluten development
- Enhance dough extensibility
The dough becomes easier to work with later.
Step 2: Add Salt
Sprinkle salt over the dough.
Mix thoroughly using your hands.
Continue until the salt is fully incorporated.
The dough will begin feeling stronger.
Step 3: Divide the Dough
Separate approximately:
- One-third of the dough
into a second bowl.
Leave the remaining two-thirds in the original bowl.
You now have:
- Plain dough
- Chocolate dough portion
Step 4: Create the Chocolate Dough
Mix together:
- Cocoa powder
- Warm water
until smooth.
Add this cocoa mixture to the smaller dough portion.
Knead gently until fully incorporated.
The dough should become evenly chocolate-colored.
Why Mix Cocoa Separately?
Combining cocoa with water first prevents:
- Clumping
- Uneven streaks
- Dry pockets
This creates a smoother chocolate dough.
Step 5: Begin Bulk Fermentation
Cover both doughs.
Allow them to rest for:
30 minutes
at room temperature.
Step 6: First Stretch and Fold
Perform stretch-and-folds on both doughs.
Lift one side of the dough.
Stretch upward.
Fold toward the center.
Rotate and repeat.
Complete four folds per dough.
What Stretch and Folds Do
Stretch-and-fold techniques help:
- Build gluten
- Improve strength
- Create structure
Without intensive kneading.
Step 7: Continue Bulk Fermentation
Perform additional stretch-and-fold sessions every:
30 minutes
for approximately:
2 hours
Complete a total of 4 sets.
The dough should become smooth and elastic.
Optional Chocolate Additions
After the second fold, you may add:
- Dark chocolate chips
- Chopped chocolate
for pockets of melted chocolate throughout the loaf.
Fold gently to distribute evenly.
Step 8: Allow Final Bulk Rise
After completing stretch-and-folds:
Cover both doughs.
Allow them to ferment until increased in volume by approximately:
50–75%
This may take:
4–6 hours
depending on room temperature.
Signs Bulk Fermentation Is Complete
The dough should:
- Feel airy
- Show bubbles
- Jiggle slightly
- Hold its shape
These signs indicate readiness.
Step 9: Shape the Marble Pattern
Lightly flour your work surface.
Gently flatten both doughs into rectangles.
Place the chocolate dough over the plain dough.
Creating Beautiful Swirls
For dramatic marbling:
Fold the layered dough like a letter.
Rotate.
Flatten gently.
Repeat the folding process two or three times.
Avoid overworking.
Distinct layers create the best marble effect.
Step 10: Final Shaping
Shape the dough into:
- Boule (round loaf)
or
- Batard (oval loaf)
Tight shaping improves oven spring.
Step 11: Place in Banneton
Dust a banneton generously with flour.
Transfer shaped dough seam-side up.
Cover with plastic wrap or a towel.
Step 12: Cold Proof
Refrigerate overnight for:
8–12 hours
This extended proof develops:
- Flavor
- Structure
- Easier scoring
Why Cold Proofing Helps
Cold fermentation creates:
- Better flavor complexity
- Improved scoring
- Stronger crust
Many artisan bakers rely on overnight proofing.
Step 13: Preheat the Oven
Place a Dutch oven inside your oven.
Preheat to:
475°F (245°C)
for at least:
45 minutes
A thoroughly heated Dutch oven is essential.
Step 14: Score the Dough
Turn the dough onto parchment paper.
Using a sharp lame:
Create one deep slash.
Or create decorative scoring patterns.
Scoring controls expansion during baking.
Step 15: Bake Covered
Transfer the dough into the hot Dutch oven.
Cover immediately.
Bake for:
25 minutes
The steam helps create maximum oven spring.
Step 16: Bake Uncovered
Remove the lid.
Reduce temperature to:
450°F (230°C)
Bake another:
20 minutes
until deeply golden.
What Makes a Great Crust?
A perfect crust should be:
- Crisp
- Deeply colored
- Slightly blistered
The Dutch oven helps achieve bakery-quality results.
Step 17: Cool Completely
Transfer bread to a cooling rack.
Allow it to cool for:
At least 2 hours
before slicing.
This is one of the most important steps.
Why Cooling Is Essential
Fresh bread continues cooking internally.
Cutting too soon may result in:
- Gummy crumb
- Compressed texture
Patience rewards you with the best slice.
