This Polish Chocolate Babka with Hazelnuts is a rich, buttery, and utterly delightful cake that hails from the wonderful tradition of Polish Jewish cuisine. Baked in a simple loaf pan for easy slicing and sharing, this swirled chocolate and hazelnut beauty is a true showstopper dessert.
In a small bowl, dissolve the yeast in warm milk with 1 tablespoon sugar. Let it sit for 5–10 minutes until frothy.
2 ¼ teaspoon dry yeast, ⅓ cup milk
In a large bowl, combine the flour, remaining sugar, and salt. Add the yeast mixture, eggs, vanilla extract, and softened butter. Knead for 8–10 minutes until smooth and elastic.
4 cups all-purpose flour, ½ cup sugar, ½ teaspoon salt, 2 large eggs, 1 teaspoon vanilla extract, 7 tablespoon unsalted butter
Cover the dough with a clean kitchen towel and let it rise in a warm place for 1.5–2 hours until doubled in size.
Mix the Filling
In a bowl, mix the melted chocolate, hazelnut spread, cocoa powder, sugar, and crushed hazelnuts until smooth.
5 oz dark chocolate, ⅓ cup hazelnut spread, 2 tablespoon cocoa powder, 2 tablespoon sugar, ½ cup crushed hazelnuts
Assemble the Babka
Roll out the dough into a large rectangle (about ½ cm thick).
Spread the filling evenly over the dough. Roll it tightly into a log and then cut it lengthwise into two strips. Twist the two strips together, keeping the cut sides facing up.
Second rise: Place the twisted dough into a greased loaf pan. Cover and let it rise for another 45–60 minutes.
Preheat the oven to 350°F (180°C). Bake for 35–40 minutes until golden brown.
Prepare the Syrup
While the babka bakes, heat the water, sugar, and vanilla extract in a saucepan until the sugar dissolves. Let it cool slightly.
⅓ cup water, ½ cup sugar, ½ teaspoon vanilla extract
As soon as the babka is out of the oven, brush it with the syrup to keep it moist and glossy. Let the babka cool slightly before slicing.
Notes
Use room temperature ingredients.
Knead until the dough is smooth and elastic but avoid over-kneading.
Proper rising is crucial for a light and airy texture.
For a wider, more shallow cake, use a 5 x 9 loaf pan instead of the 4 x 8 loaf pan.
