Divide dough into two 28-30-ounce portions. If you don’t have a scale, you can eyeball it. Round each portion to an oval shaped piece of dough by pulling and tucking it under. This will make it easier to roll out into a rectangle.
Flour your work surface and roll dough out to a rectangular shape, about 10 inches by 18 inches.
Spread half of the filling onto the dough, leaving a one inch border at the top edge. Leaving this border will help seal the dough shut when rolled up.
Start with the long side closest to you, and working from left to right begin to roll dough up. You can tug and pull as you go, tightening the roll. This can get messy - if peaches are sliding out, tuck them back in as best as you can. You can also place any extra peaches on top of the rolls.
Once rolled up, pinch the seam shut.
Using a piece of floss or sharp knife, make a light indentation where your cuts will be. One rollout will give you 9 large rolls. This will be your guide to know where to cut and to help make them all the same size.
Cut the peach rolls and repeat with the second piece of dough.
Place peach cinnamon rolls on a greased baking sheet about 1-2 inches apart. Cover with plastic wrap and let proof for about 45-60 minutes, or until they double in size.
