YEASTED CHOCOLATE COFFEE CAKE
Make the bread. In a medium bowl mix the yeast and a pinch of sugar with the milk and let stand for about 5 minutes, or until foamy. In another bowl, whisk together the remaining sugar and the egg. Whisk into the yeast mixture. In the bowl of a stand mixer fitted with the dough-hook attachment, combine the flour and kosher salt. Add the egg mixture and mix on low speed until almost fully combined, add the butter. Mix until smooth, soft, and slightly sticky, about 9-10 minutes. Grease a large bowl. Turn out the dough onto a floured surface and knead until smooth. Place in the greased bowl and cover with plastic wrap. Let stand in a warm place until doubled in size, for about 1 – 1.5 hours.
Make the filling. In the food processor with large blade attachment grind chocolate and butter. Add salt, cinnamon, and sugar to the mixture.
“Once the dough has doubled in size, place it on a flour work surface. Let rest for 5 minutes and then roll it out into an 18-inch square. Sprinkle all but ½ cup of the filling over the dough, leaving a 1-inch border. Brush the edges with the egg wash. Tightly roll the dough from one end to the other. Pinch the seams to seal. Fold in half and form a “U” shape. Twist 2 or 3 into a braid. Make sure to pinch the ends of braid together. Grease a 5-by-10-inch loaf pan, line with parchment, leaving 1-inch overhangs; then grease the parchment paper. Place the dough in the pan and brush with egg wash.”
Make the topping. In a small bowl combine the confectioners’ sugar, flour, butter, and the reserved filling. Sprinkle it over the bread. It’s ok, if the filling falls down the edges.
Preheat the oven to 350⁰F/175⁰C. Cover the bread with plastic wrap and let rise for about 30 minutes.
Please bread pan on a sheet and position it on the center rack in the oven. Bake for about 55 minutes. Reduce temperature to 325⁰F/160⁰C, and bake for another 15 minutes till golden brown.
Cool the bread in the pan on a wire rack before removing it.
