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 butter over the surface of the dough. Sprinkle about 1/3 cup of the cinnamon sugar mixture on top of the butter.
Place a piece of floss in the center of the dough, lengthwise, creating a visual guide.
Start with one corner and along the 18-inch side, begin to roll the dough up. You can tug and pull as you go which will tighten the roll and make more swirls. Roll towards the center where the floss. Stop rolling when you get to the center. Then repeat with the other 18-inch side towards the center - meeting them both in middle.
Pull the floss out and use it to cut 9, 2-inch cinnamon rolls. Simply wrap each end of the floss around your index fingers, slide it under the dough, bring each end of the floss up, cross and tug. It will create a clean cut without smashing your cinnamon rolls. There should be two side-by side swirls connected at the bottom.
Place the rolls on a baking pan lined with parchment paper, about 2 inches apart. With lightly floured fingers, gently flatten the rolls while pinching the bottom into a point, forming a heart. Once all of your cinnamon rolls are shaped, cover them with a clean kitchen towel and let them rise until doubled in size, depending on how warm your kitchen is, it should take about 45 - 60 minutes.
