Roll out the dough to a rectangle measuring 18” x 10”.
Using an offset spatula spread the apple mixture over the dough, leaving about 1” without filling along one 18” side.
Tightly roll up the dough from the long side where the filling goes to the end. Pinch the dough to seal.
Cut the roll in half so you have 2 9” rolls.
Working with one roll at a time, cut each roll down the middle lengthwise.
Lay the 2 pieces side by side with the filling facing up. Twist the pieces together and place on a parchment lined baking sheet, approximately 12” x 16”.
Repeat with the second roll.
Preheat oven to 350 degrees Fahrenheit.
Cover the twist loosely with plastic wrap and then a dish towel. Lest it rise for about 30 minutes, or until the twists are slightly puffed and spring back when pressed with your finger that has been dipped in flour.
After the second rising, brush the twists with the egg wash and cover with the crumb topping.
Bake for 30-35 minutes or until the interior temperature measures 190°. The twists should be golden brown. Be careful not to overbake or the twist wil be dry.
Remove from the oven and place the baking sheet on a rack to cool.
After about 15 minutes, carefully remove the twists from the pan and place them directly on the rack to cool.
