Yield: 1 large loaf or 10–12 brioche rolls
Ingredients
For the Sourdough Brioche Dough
- 100 g active sourdough starter (100% hydration, bubbly and recently fed)
- 500 g bread flour
- 80 g granulated sugar
- 10 g fine sea salt
- 180 g whole milk, slightly warm
- 3 large eggs (about 150 g without shells)
- 200 g unsalted butter, softened and cut into small pieces
- 1 teaspoon vanilla extract
For the Chocolate Filling
- 150–200 g dark chocolate chips or chopped chocolate
- 2 tablespoons cocoa powder
- 2 tablespoons brown sugar
- 1 tablespoon melted butter
- Optional: ½ teaspoon espresso powder for deeper chocolate flavor
For the Egg Wash
- 1 egg yolk
- 1 tablespoon milk or cream
Instructions
Step 1: Prepare the Sourdough Dough
Make sure your sourdough starter is active and at its peak before beginning. A ready starter should look bubbly, have a pleasant fermented aroma, and be able to rise after feeding.
In the bowl of a stand mixer, combine the bread flour, sugar, and salt. Add the sourdough starter, milk, eggs, and vanilla extract. Mix on low speed until the ingredients come together into a rough dough.
Continue mixing for about 5–8 minutes until the dough becomes smoother and begins to develop elasticity. Brioche dough is naturally soft and sticky because of its high butter and egg content, so avoid adding extra flour unless absolutely necessary.
Step 2: Add the Butter
With the mixer running on medium-low speed, gradually add the softened butter one piece at a time. Allow each piece to fully incorporate before adding more.
This process may take 10–15 minutes. At first, the dough may look separated or greasy, but continue mixing until it becomes smooth, shiny, and stretchy.
The finished dough should be soft, silky, and able to stretch without breaking easily.
Step 3: First Fermentation
Transfer the dough to a lightly greased bowl. Cover with a lid or plastic wrap and let it ferment at room temperature for 4–6 hours, or until it increases in size by about 50–75%.
Because sourdough fermentation depends on starter strength and room temperature, the timing may vary. A cooler kitchen will require more time.
For better flavor development, place the dough in the refrigerator overnight after the initial rise. The cold fermentation will improve the texture and make shaping easier.
Step 4: Prepare the Chocolate Filling
While the dough is chilling or resting, prepare the chocolate mixture.
Combine cocoa powder, brown sugar, espresso powder (if using), and melted butter to create a thick chocolate paste. Prepare the chopped chocolate or chocolate chips separately.
The combination of chocolate paste and chocolate pieces creates a richer filling with both intense cocoa flavor and melted chocolate pockets.
Step 5: Shape the Brioche
Remove the dough from the refrigerator and place it on a lightly floured surface.
Roll the dough into a large rectangle. Spread the chocolate mixture evenly over the surface, then sprinkle with chopped chocolate.
Fold or roll the dough depending on the shape you prefer:
For a loaf:
- Roll the dough tightly into a log.
- Place it into a greased loaf pan.
- Tuck the ends underneath for an even shape.
For braided brioche:
- Divide the dough into three equal pieces.
- Roll each piece into a rope.
- Braid the ropes together and place in a loaf pan.
For individual rolls:
- Cut the dough into equal portions.
- Shape each piece into a smooth ball.
- Arrange in a baking dish.
Step 6: Final Proof
Cover the shaped dough and allow it to rise at room temperature for 3–5 hours, depending on temperature.
The brioche is ready when it looks noticeably lighter, puffy, and slowly springs back when gently pressed.
Avoid over-proofing, as the dough may lose structure and become difficult to bake.
Step 7: Bake the Brioche
Preheat the oven to 175°C (350°F).
Whisk together the egg yolk and milk to make the egg wash. Brush the surface of the brioche gently with the mixture.
Bake for:
- Large loaf: 35–45 minutes
- Rolls: 20–25 minutes
The brioche should have a deep golden color and an internal temperature of approximately 90–93°C (194–199°F).
If the top browns too quickly, cover loosely with aluminum foil during the final part of baking.
Step 8: Cool and Serve
Allow the brioche to cool in the pan for 10–15 minutes, then transfer it to a wire rack.
For the best texture, let it cool for at least 1 hour before slicing. The crumb continues to set as it cools.
Enjoy warm slices on their own, toasted with butter, or paired with jam, honey, or chocolate spread.
Tips for Perfect Sourdough Chocolate Brioche
Use an Active Starter
A strong sourdough starter is essential for a light and fluffy brioche. Feed your starter several hours before baking so it is energetic and full of bubbles.
Use Soft Butter
Butter should be softened but not melted. Soft butter blends into the dough gradually and creates the signature rich brioche texture.
Be Patient With Fermentation
Sourdough brioche takes time because natural fermentation works slowly. Longer fermentation creates better flavor and a more delicate crumb.
Choose Quality Chocolate
Good-quality dark chocolate or semi-sweet chocolate gives the best balance between sweetness and richness. Chocolate chunks create beautiful melted pockets throughout the loaf.
Storage Instructions
Store sourdough chocolate brioche in an airtight container or wrapped tightly at room temperature for up to 3 days.
For longer storage, freeze slices or the entire loaf for up to 2 months. Thaw at room temperature and gently warm before serving.
Serving Ideas
- Toast slices and serve with butter
- Make a luxurious French toast
- Serve with fresh berries and whipped cream
- Pair with espresso, coffee, or tea
- Use leftover brioche for bread pudding
This sourdough chocolate brioche is a beautiful example of how simple ingredients, patience, and natural fermentation can create a bakery-quality homemade bread with incredible flavor and texture.
