This sweet yeast cake is full of chocolate flavors
- 1½cupswarm milk(110°F)
- 2envelopes active dry yeast((1/2 ounce))
- 1¾cupsplus a pinch of sugar
- 3whole large eggs plus 2 large egg yolks(room temperature)
- 6cupsall-purpose flour(plus more for dusting)
- 3½sticksunsalted butter, cut into 1-inch pieces, room temperature, plus more for bowl and pans((1¾ cups))
- 2poundssemisweet chocolate(very finely chopped)
- 1tablespoonplus 1 teaspoon ground cinnamon
- 1tablespoonheavy cream
For Streusel Topping:
- 1-2/3cupsconfectioners' sugar
- 1-1/3cupsall-purpose flour
- 1½sticksunsalted butter, room temperature((¾ cup))
- 1. In a small bowl, sprinkle yeast and a pinch of sugar over the warm milk; stir until dissolved. Let stand until foamy, about 5 minutes. In a medium bowl, whisk together ¾ cup sugar, 2 eggs, and the yolks; add yeast mixture, and whisk to continue.
- 2. In the bowl of an electric mixer fitted with the paddle attachment, combine flour and salt. Add the egg mixture, and beat on low speed until almost all the flour is incorporated, about 30 seconds. Switch to the dough hook. Add 2 sticks butter, and beat until completely incorporated and a smooth, soft dough forms, about 10 minutes. The dough should still be slightly sticky when squeezed.
- 3. Turn out dough onto a lightly floured work surface, and knead a few times until smooth. Place dough in a well-buttered bowl, and turn to coat with butter. Cover tightly with plastic wrap. Let rise in a warm place until doubled in bulk, about 1 hour.
- 4. To make the Streusel Topping:Combine sugar and flour in a large bowl. Using a pastry blender, cut in butter until mixture resembles coarse crumbs with some larger clumps remaining. Set aside.
- 5. In a bowl, stir together chocolate, remaining cup sugar, and the cinnamon. Using a pastry blender, cut in remaining 1½ sticks butter until combined; set aside filling.
- 6. Generously butter three 9-by-5-by-2¾-inch loaf pans and line with parchment paper, leaving a 1½-inch overhang along the sides. Brush more butter over the parchment, and set aside. Punch down the dough, and transfer to a clean work surface. Let the dough rest 5 minutes.
- 7. Meanwhile, beat the remaining egg with the cream. Cut dough into three equal pieces. On a well-floured work surface, roll out one piece of dough to a 16-inch square, about 1/8 inch thick. (Keep other pieces covered with plastic wrap while you work.) Brush edges of dough with the egg wash. Crumble one-third of the chocolate filling evenly over dough, leaving about a ½-inch border on the long sides. Roll up dough lengthwise into a tight log, pinching ends together to seal. Twist dough evenly down the length of the log, a full five or six times. Brush the top of the log with egg wash. Crumble 2 tablespoons filling down the center of the log, being careful not to let mixture slide off. Fold log in half into a horseshoe shape, then cross the right half over the left. Pinch ends together to seal and form a figure eight. Twist two more times, and fit into a prepared pan. Repeat with remaining dough and filling.
- 8. Preheat the oven to 350°F, with a rack in the lower third. Brush the top of each loaf with egg wash; sprinkle with one-third of the Streusel Topping. Loosely cover each pan with plastic wrap, and let rise in a warm place until dough has expanded and feels pillowy, about 40 minutes.
- 9. Bake loaves, rotating halfway through, until golden, about 55 minutes. Reduce oven temperature to 325°F; bake until loaves are deep golden, 20 to 30 minutes more. (If the tops begin to brown too quickly, tent with aluminum foil.) Transfer pans to wire racks to cool completely. Babkas can be wrapped in plastic and kept at room temperature for up to 3 days.
- Note: A babka can be frozen in the pan for up to a month before baking. When ready to bake, remove from freezer; let stand at room temperature for about five hours. Be careful not to underbake; otherwise, the center may not set properly.
