- 2 tablespoons water
- 1 teaspoon vanilla extract

- 50ml water
Equipment Needed
- Mixing bowl
- Stand mixer (optional)
- Rolling pin
- Saucepan
- Loaf pan (9 x 5 inch)
- Pastry brush
- Sharp knife
- Cooling rack
Instructions
Step 1: Prepare the Sourdough Starter
Feed your sourdough starter 4–6 hours before making the dough. It should be active, bubbly, and doubled in size.
Intensity: Low
A healthy starter ensures proper fermentation and gives the babka its characteristic flavor and texture.
Step 2: Mix the Dough
In a large mixing bowl, combine:
- Active sourdough starter
- Milk
- Eggs
- Sugar
Whisk until smooth.
Add the bread flour, all-purpose flour, and salt. Mix until a rough dough forms.
Gradually add softened butter, kneading after each addition until fully incorporated.
Continue kneading for 10–12 minutes until the dough becomes smooth, elastic, and slightly tacky.
Intensity: Medium
The dough should pass the windowpane test, meaning a small piece can stretch thin without tearing.
Step 3: Bulk Fermentation
Transfer the dough to a lightly greased bowl.
Cover and let rise at room temperature for 6–8 hours, or until increased by about 50%.
Perform three sets of stretch-and-folds during the first 90 minutes.
Stretch-and-Fold Schedule
- After 30 minutes
- After 60 minutes
- After 90 minutes
Intensity: Low
These folds strengthen gluten development and improve the final structure of the bread.
Step 4: Make the Blueberry Filling
While the dough ferments, prepare the filling.
In a saucepan, combine:
- Blueberries
- Sugar
- Lemon juice
Cook over medium heat for about 5 minutes until berries begin to soften.
Mix cornstarch and water in a small bowl to form a slurry.
Add the slurry to the blueberry mixture and cook for another 2–3 minutes until thickened.
Stir in vanilla extract.
Remove from heat and allow to cool completely.
Intensity: Medium
The filling should be thick and spreadable rather than runny.
Step 5: Cold Proof the Dough
After bulk fermentation, cover the dough tightly and refrigerate overnight for 8–12 hours.
Intensity: None
Cold dough is easier to roll and shape, while the extended fermentation develops flavor.
Step 6: Roll Out the Dough
The next day, lightly flour your work surface.
Roll the chilled dough into a rectangle approximately 12 x 18 inches.
Spread the cooled blueberry filling evenly over the surface, leaving a 1-inch border around the edges.
Intensity: Medium
Try to distribute the filling evenly to create consistent swirls throughout the loaf.
Step 7: Shape the Babka
Starting from the long edge, tightly roll the dough into a log.
Using a sharp knife, cut the log lengthwise down the center.
Position the cut sides upward.
Twist the two halves together, exposing the blueberry layers.
Carefully transfer the braid into a greased loaf pan.
Intensity: Medium to High
This step creates the classic babka appearance and beautiful marbled interior.
Step 8: Final Rise
Cover the loaf pan loosely.
Allow the shaped babka to rise at room temperature for approximately 2 hours.
The dough should become puffy and slightly expanded.
Intensity: Low
Avoid over-proofing, which can cause the loaf to collapse during baking.
Step 9: Bake
Preheat oven to 350°F (175°C).
Place the loaf on the center rack.
Bake for 40–45 minutes until:
- Deep golden brown
- Internal temperature reaches 190–200°F (88–93°C)
- Top sounds hollow when tapped
If the top browns too quickly, tent loosely with foil during the final 15 minutes.
Intensity: Medium
Proper baking ensures a fully cooked interior without drying out the loaf.
Step 10: Prepare the Syrup
While the babka bakes, combine sugar and water in a small saucepan.
Bring to a gentle simmer and stir until the sugar dissolves completely.
Remove from heat.
Intensity: Low
This simple syrup helps maintain moisture and adds a glossy finish.
Step 11: Glaze the Babka
Immediately after removing the loaf from the oven, brush the syrup generously over the surface.
Allow the bread to cool in the pan for 15 minutes.
Transfer to a wire rack and cool completely before slicing.
Intensity: Low
The syrup enhances flavor and keeps the bread soft for several days.

Tips for Success
- Use an active sourdough starter for reliable fermentation.
- Fully cool the blueberry filling before spreading.
- Chill the dough overnight for easier shaping.
- Roll the dough tightly to create defined swirls.
- Avoid adding excess flour during rolling.
