Ingredients

Scale

Starter

1 cup Unfed Sourdough Starter (can use store-bought as a substitute)
1 cup All-Purpose Flour
0.5 cup Water (filtered)
0.25 cup Light Brown Sugar

Dough

2.5 cups All-Purpose Flour (bread flour optional for chewier texture)
0.25 cup Cornstarch
Prepared Sweet Starter (from above)
2 large Eggs (or flax eggs for vegan option)
0.5 cup Whole Milk (or plant-based milk)
1 teaspoon Salt
0.25 cup Granulated Sugar (or coconut sugar for lower glycemic option)
0.5 cup Unsalted Butter (softened, or vegan butter for dairy-free)

Filling

0.5 cup Heavy Cream (or coconut cream for dairy-free)
8 ounces Dark Chocolate (70% cacao preferred, chopped)
0.25 cup Cocoa Powder
0.25 cup Granulated Sugar
1 tablespoon Unsalted Butter
1 teaspoon Vanilla Extract
0.5 cup Walnuts (optional, substitute with pecans or omit)

Syrup

0.25 cup Granulated Sugar
0.25 cup Water (warm)

Instructions

Prepare Sweet Starter: In a bowl, combine 1 cup unfed sourdough starter, 1 cup all-purpose flour, 1/2 cup water, and 1/4 cup light brown sugar. Mix until combined, cover the bowl, and let it ferment at room temperature for 6-8 hours to develop flavor and activity.
Mix Dough: In a stand mixer fitted with a dough hook, add 2.5 cups all-purpose flour, 1/4 cup cornstarch, the prepared sweet starter, 2 eggs, 1/2 cup whole milk, 1 teaspoon salt, and 1/4 cup granulated sugar. Mix on medium speed for 3-5 minutes until the dough comes together and is smooth.
Knead and Proof: Gradually add 1/2 cup softened unsalted butter to the dough while kneading on low speed for 8-10 minutes until fully incorporated and elastic. Cover the dough and allow it to proof at room temperature for 4-6 hours until it visibly rises and slightly puffs, or refrigerate overnight for a slow proof.
Prepare Filling: Heat 1/2 cup heavy cream in a saucepan until steaming but not boiling. Pour over chopped 8 ounces dark chocolate and stir until smooth. Mix in 1/4 cup cocoa powder, 1/4 cup granulated sugar, 1 tablespoon unsalted butter, and 1 teaspoon vanilla extract. Stir to combine fully and let cool to room temperature.
Shape Loaf: On a lightly floured surface, roll the proofed dough into a 1/4 inch thick rectangle. Spread the cooled chocolate filling evenly over the dough, sprinkle 1/2 cup walnuts evenly if using. Roll the dough tightly into a log from the long side. Slice the log lengthwise down the center to expose the layers, then twist the two halves around each other with the cut sides facing up. Place the twisted loaf into a greased loaf pan, cover, and proof for another 2-4 hours until puffed and risen.
Bake: Preheat the oven to 175°C (350°F). Bake the babka for 35-40 minutes until the top is golden brown. If it begins to brown too quickly, tent with aluminum foil to prevent burning.
Finish with Syrup: While baking, heat 1/4 cup granulated sugar and 1/4 cup water in a small pan until the sugar is completely dissolved to make a syrup. As soon as the babka is out of the oven, brush the syrup generously over the entire surface to create a shiny glaze. Allow the babka to cool completely before slicing and serving.

Notes

Using bread flour instead of all-purpose flour will yield a chewier texture in the bread.
The sourdough starter should be active; unfed starter is used here to develop a mild tang and sweetness.
For a dairy-free option, plant-based milk, vegan butter, and coconut cream can be substituted as noted.
Walnuts are optional and can be replaced with pecans or omitted for nut-free preference.
Resting and proofing times may vary depending on ambient temperature; the dough should be visibly risen but not overproofed.
Tent the babka with foil during baking if it browns too rapidly to avoid burning the crust.
The syrup glaze not only adds shine but also keeps the babka moist and enhances sweetness.
