Chocolate Babka

DIRECTIONS

• Generously grease 2, 9x5 inch bread pans.
• In a small saucepan, warm the milk and butter until butter melts.
• In a mixing bowl, combine the bread flour, 2 cups all-purpose flour, yeast, and 1/4 cup sugar.
• Add water, the milk-butter mixture, egg, and salt to dry ingredients and mix well.
• Knead dough until smooth and elastic, about 15 minutes.
• Cover dough with a warm, damp cloth and let rise in a warm draft-free area until doubled in size, about 1 to 1-1/2 hours.
• For the chocolate filling: In a medium bowl, stir together the finely chopped chocolate, cinnamon, and 1/4 cup sugar.
• Cut in 1/4 cup chilled butter.
• For the streusel topping: In a medium bowl, combine the powdered sugar and 1/4 cup all-purpose flour.
• Cut in 1/4 cup chilled butter until the mixture resembles coarse crumbs.
• When the dough has doubled, punch down and cut it into two equal pieces.
• Loosely shape each piece into a ball.
• Cover the dough with a warm, damp cloth and let it rest for 10 minutes.
• Roll out one portion on a lightly floured surface to form a 15 inch square.
• Sprinkle with half the chocolate filling, roll up to form a log, and seal the seam and ends.
• Twist the dough, like wringing out a towel.
• Bring the two ends together, folding the dough in half.
• Twist the dough again on itself, in a twisting motion, to form the loaf.
• Place loaf in prepared pan, cover with warm, damp cloth and let rise until doubled, about 30 minutes.
• Repeat with second dough ball.
• Preheat an oven to 350°F.
• Brush the loaves with the egg wash, if desired.
• Sprinkle streusel on top.
• Bake the loaves for 25 to 30 minutes until the bread is a deep golden brown.
