Once the dough has risen fully, preheat the oven to 375 degrees Fahrenheit and line a large 9x13 baking dish with parchment paper, allowing excess to hang from the sides.
Add a bit of flour to a surface and place the dough onto it, lightly adding a bit of flour to the top. Using a rolling-pin, roll out the dough into a rectangular shape (approximately 9″x14 and 1/2-inch thick), trimming the edges if needed.
Then, generously spread the softened butter (using a spatula) atop dough, followed by the brown sugar-cinnamon mixture, ensuring that the top is coated evenly. Add the diced apples atop the dough evenly.
Now, using a pizza cutter (this is easier), cut about 5-6 cuts vertically and horizontally until you've made about 15-20 small rectangular pieces.
Carefully, stack each rectangular piece atop each other in groups (about 6-7 at a time) and place them in the prepared loaf pan standing upward and placing each group one behind the other tightly to form a "loaf-like" shape.
Bake the bread in the oven for approximately 45 minutes to an hour or until the center comes out "clean" when tested with a knife or cake tester.
Remove from the oven and let it cool completely.
