Grease two eight-inch loaf pans and line them with parchment paper.
Gently punch the dough, then divide it into two equal parts.
Roll each part over a lightly floured work surface into a 12x16-inch rectangle (or 12x18-inch if using 9-inch pans).
Top the dough with the longer side facing you with the apples, leaving one -nch gap at the center, sides, and bottom.
Roll the dough, starting from the long side, into a log.
Fold the dough into a U shape.
Twist the two sides of the dough around each other.
Gently lift the dough and place it in the prepared pan. Repeat with the second part.
Brush with the egg wash, and top with the streusel.
Set aside for the second rise, about 90 minutes.
About 30 minutes before baking, preheat the oven to 350F (180C).
Bake for 30-33 minutes on the middle rack until the temperature on the middle reaches 180F.
Remove from the oven and allow to cool for 20-30 minutes before slicing.
