Instructions

1. In the bowl of a stand mixer with the paddle attachment or a large mixing bowl with a wooden spoon, combine the milk, butter, yeast, sugar, salt, cinnamon, eggs and 3 cups of the flour. Mix until it forms a thick batter.
2. If working on a stand mixer, switch to the dough hook. With the mixer running, add the remaining flour. The dough should gather on the hook and clears the sides of the bowl. Sprinkle a little more flour if necessary. If working by hand mix as much flour as you can with the spoon, then finish kneading in the rest of the flour by hand. Knead the dough for 5 minutes.
3. Turn the dough out onto a floured surface and knead to a smooth ball. The dough should be soft and silky.
4. Place the dough into a lightly oiled bowl, turning once to coat the dough. Cover the bowl and set it aside to let it rise in a warm spot until doubled in size, about 1 1/2 hours.
5. Toss the apple cubes with the granulated sugar and set aside to macerate for at least 1 hour (do this while the dough rises)

Assembly

1. Combine the brown sugar, cinnamon and salt in a small bowl. Drain the apples, reserving the juice. Dump the apples onto a paper towel or clean kitchen towel to blot them dry. Generously butter two 8"x 4" loaf pans.
2. Turn the dough out onto a lightly floured surface. Roll to a 16"x 16" square. Brush the surface of the dough with egg wash. Sprinkle the apple cubes over the lower half of the dough. Fold the top half of the dough over the apples. Gently roll over the dough with a rolling pin or pat with your hands to embed the apples in the dough. You should now have a 8" x 16" rectangle of dough with the long side facing you.
3. Divide the dough in 1/2 so you have two 8" x 8" squares of dough. Brush one piece of dough with egg wash and sprinkle half of the cinnamon sugar over the dough. Tightly roll the dough into a log, pinching the seam together. Place the dough, seam side down, into one of the prepared pans. Repeat with the remaining dough and filling. Cover the pans with oiled plastic wrap and rise until almost doubled in volume, about 1 hour (see note to work ahead).
4. Preheat the oven to 350F.
5. To check if the dough is ready, poke the dough. If the dough springs right back it's not ready. If the dimple slowly fills in the dough is ready for the oven.
6. Bake until the bread is golden brown and the internal temperature is 195F-200F, about 45 minutes. Cool the bread in the pan for 10 minutes then turn out onto a cooling rack.
7. Combine the confectioner's sugar with enough of the reserved the apple juice to make an icing with the consistency of pancake batter.
8. When the bread is still slightly warm, drizzle half the glaze over each loaf. Spread the glaze to cover the top of the bread. The glaze will set while the bread finishes cooling.
