Turn the proofed dough out onto a clean, lightly floured surface. Fold it over itself a few times to release any big air bubbles, then, using a rolling pin, roll the dough into a large rectangle about 11" by 14".
With the long side facing you, spread the filling evenly over the surface of the dough, avoiding the inch of dough that is farthest away from you. This will make it easier to seal the roll to keep it nice and tight.
Roll the dough away from you as tightly as you can. You will end up with a 14" log.
Cut the dough evenly into 8 pieces. I like to use a piece of dental floss for this, to avoid squishing the dough. Just slide the dental floss under the log, and cross it over the top to cut the rolls. To make sure all the rolls are of equal size, start by cutting the entire log in half, then cut the halves in half, then the quarters in half.
Place the rolls spiral-side up in a greased baking dish. I'm using a 9x13, but a slightly smaller dish would give you softer sides, as the cinnamon rolls would squish together more when they rise & bake.
Cover with plastic, and allow the rolls to rise for 45-60 minutes or until nicely puffed.
Preheat the oven to 350F, then bake the cinnamon rolls on the middle rack for 25 minutes. They should be lightly golden, but not too dark.
