Directions
<ol class="no-list-style"><li class="MethodStepper"><h4 class="step-title">Step 1</h4>Begin by preparing your dough. In the bowl of your stand mixer, combine the lukewarm milk and yeast, stirring gently. Let it sit for 5-10 minutes until foamy, which indicates the yeast is active. This activation step is crucial for a proper rise.</li><li class="MethodStepper"><h4 class="step-title">Step 2</h4>Add the eggs, sugar, vanilla, and salt to the yeast mixture. Mix on low speed using the dough hook until combined. Gradually add the flour, mixing until incorporated. The dough will look shaggy at this point, which is exactly what we want.</li><li class="MethodStepper"><h4 class="step-title">Step 3</h4>With the mixer running on medium-low speed, add the softened butter one cube at a time, waiting until each piece is fully incorporated before adding the next. This slow addition is essential for proper emulsification and will create that signature brioche-like texture. Continue mixing for 8-10 minutes until the dough is smooth, elastic, and pulls away from the sides of the bowl.</li><li class="MethodStepper"><h4 class="step-title">Step 4</h4>Transfer the dough to a lightly oiled bowl, cover with plastic wrap, and let rise in a warm place until doubled in size, about 1.5-2 hours. The slow rise develops flavor and structure in your dough, so resist the urge to rush this step.</li><li class="MethodStepper"><h4 class="step-title">Step 5</h4>While the dough rises, prepare your chocolate filling. In a heatproof bowl, melt the chocolate and butter together using a double-boiler or in 30-second intervals in the microwave, stirring between each interval. Once smooth, stir in the powdered sugar, cocoa powder, and cinnamon. Allow to cool slightly until it reaches a spreadable consistency.</li><li class="MethodStepper"><h4 class="step-title">Step 6</h4>For the streusel topping, mix the flour, sugar, and salt in a bowl. Add the cold butter and work it in with your fingertips until crumbly pea-sized pieces form. Refrigerate until ready to use. Cold butter creates those perfect little nuggets of streusel that provide textural contrast.</li><li class="MethodStepper"><h4 class="step-title">Step 7</h4>Once the dough has doubled, punch it down gently to release air bubbles. On a lightly floured surface, roll the dough into a large rectangle approximately 40x50cm (16x20 inches). The dough should be thin but not tearing – aim for about 5mm thickness.</li><li class="MethodStepper"><h4 class="step-title">Step 8</h4>Using an offset spatula, spread the chocolate filling evenly across the entire surface, leaving a 1cm border along one long edge. Work quickly but carefully – if the filling is too firm to spread easily, warm it slightly.</li><li class="MethodStepper"><h4 class="step-title">Step 9</h4>Starting from the long edge (opposite the clean border), tightly roll the dough into a log, pinching the clean edge to seal. A tight roll will create those beautiful, defined swirls in your finished babka rolls.</li><li class="MethodStepper"><h4 class="step-title">Step 10</h4>Using a sharp knife or unflavored dental floss, cut the log into 12 equal pieces. Place each roll into a greased baking dish or muffin tin, cut side up. Cover loosely with plastic wrap and let rise again for about 30-45 minutes, until puffy but not quite doubled.</li><li class="MethodStepper"><h4 class="step-title">Step 11</h4>Preheat your oven to 180°C (350°F). Before baking, sprinkle the streusel topping generously over each roll. Bake for 22-25 minutes until golden brown and a skewer inserted in the center comes out clean. The internal temperature should reach about 88°C (190°F) when fully baked.</li><li class="MethodStepper"><h4 class="step-title">Step 12</h4>While the rolls are baking, prepare the simple syrup if using. Combine water and sugar in a small saucepan and bring to a boil, stirring until sugar dissolves. Remove from heat and let cool slightly.</li><li class="MethodStepper"><h4 class="step-title">Step 13</h4>As soon as the rolls come out of the oven, brush them lightly with simple syrup. This adds a subtle sweetness and keeps them moist. Let the babka rolls cool in the pan for 15 minutes before transferring to a wire rack to cool completely. The cooling period allows the structure to set – cutting too soon will result in a gummy texture.</li><li class="MethodStepper"><h4 class="step-title">Step 14</h4>These chocolate babka rolls are best enjoyed the day they're made, but will keep in an airtight container at room temperature for up to 2 days. For longer storage, freeze for up to a month and reheat in a 150°C (300°F) oven for 10 minutes before serving.</li></ol>
