The next day, begin making the apple cinnamon sauce for the filling. In a small sauce pan, add the butter, sugar, cinnamon, vanilla, cubed apples, apple sauce, and flour. Heat the apple cinnamon mixture, stirring often, until the apples, sugar, and flour have thickened and become fully incorporated. There will be softened cubes of apples in the sauce.
Lightly flour the counter and roll out the dough into a rectangular shape, measuring about 18 inches by 10 inches.
Roll the dough starting at the long side of the dough. As you are rolling, try to keep as much of the filling in between the layers of the rolls. If any filling seeps out, place it evenly on top of the rolls in the pan.
Then, cut the rolls using an unwaxed and unscented floss. I like silk floss. Start by cutting the rolls in half. Then, each half will be cut in half until you have 16 cut rolls.
Place the cut rolls in a 9×13 pan and top evenly with the remaining 1/2 cup of milk. Cover the allow to rise in a warm place for about an hour.
Preheat the oven to 350F. I like to place the rolls on the back of the stove top so that as the oven is preheating, the rolls are in a warm spot to rise.
Bake the rolls for 30 minutes or until the tops of the rolls are lightly brown and the middle rolls don’t appear soggy.
