Ingredients
For the Dough
- 500g bread flour
- 100g active sourdough starter
- 250ml whole milk
- 50g granulated sugar
- 1 large egg
- 60g unsalted butter, softened
- 8g salt
For the Blueberry Filling
- 300g fresh or frozen blueberries
- 80g sugar
- 1 tablespoon lemon juice
- 1 tablespoon cornstarch
Optional Syrup
- 50g sugar
- 50ml water
Step 1: Prepare the Dough
In a large mixing bowl, combine the bread flour, active sourdough starter, milk, sugar, and egg. Mix until a rough dough forms. Cover and allow the dough to rest for 30 minutes. This resting period helps hydrate the flour and improves gluten development.
After resting, add the salt and softened butter. Knead the dough until smooth, elastic, and slightly tacky. This may take about 10 to 15 minutes by hand or 8 to 10 minutes using a stand mixer.
Transfer the dough to a lightly greased bowl and cover.
Step 2: Bulk Fermentation
Allow the dough to ferment at room temperature for 4 to 6 hours, depending on the temperature of your kitchen and the strength of your starter.
During the first 2 hours, perform 3 to 4 sets of stretch and folds every 30 minutes. These folds help strengthen the dough and improve the final texture.
The dough should become smoother, puffier, and show visible signs of fermentation.
Step 3: Make the Blueberry Filling
While the dough is fermenting, prepare the filling.
Add the blueberries, sugar, and lemon juice to a saucepan over medium heat. Cook until the berries begin to break down and release their juices.
Mix the cornstarch with a small amount of water and add it to the blueberry mixture. Continue cooking until thick and jam-like.
Remove from heat and allow the filling to cool completely before using.
A thick filling is important because a runny filling can make shaping difficult.
Step 4: Chill the Dough
Once bulk fermentation is complete, place the dough in the refrigerator for 1 to 2 hours.
Chilling makes the dough easier to roll out and shape, especially when working with a sweet filling.
Step 5: Roll and Fill
Lightly flour your work surface.
Roll the dough into a large rectangle approximately 12 x 16 inches.
Spread the cooled blueberry filling evenly across the dough, leaving a small border around the edges.
Starting from the long side, roll the dough tightly into a log.
Place the rolled log in the refrigerator for 15 to 20 minutes if it becomes too soft.
Step 6: Create the Signature Babka Twist
Using a sharp knife, cut the log lengthwise down the center.
You will now have two long strands exposing the beautiful blueberry layers.
Twist the two strands together while keeping the cut sides facing upward.
This step creates the dramatic swirled effect seen in every slice.
Carefully transfer the twisted loaf into a greased loaf pan.
Step 7: Final Proof
Cover the loaf loosely and allow it to proof for 2 to 4 hours at room temperature.
The loaf should become slightly puffy and airy before baking.
If preferred, you can refrigerate the shaped loaf overnight and bake it the next day.
Step 8: Bake
Preheat your oven to 350°F (180°C).
Bake the babka for 35 to 40 minutes or until deeply golden and fully baked through.
If the top begins browning too quickly, loosely cover it with foil during the last 10 minutes of baking.
The internal temperature should reach approximately 190°F to 200°F (88°C to 93°C).
Step 9: Brush with Syrup
For extra shine and moisture, prepare a simple syrup by heating equal parts sugar and water until dissolved.
Brush the warm loaf generously with the syrup immediately after baking.
This step gives the babka a beautiful glossy finish and keeps it soft for longer.
