Once the dough rises, the next step is to flatten out the dough in a large rectangle (24in x 15in), top it with the cinnamony filling, roll it up into a large cinnamon roll log, and then cut it into the actual cinnamon rolls for baking. So here we go.
Prepare a large, flat surface by lightly dusting it with flour (to avoid sticking).
Place the dough in the middle of your prepared surface. I like to form the ball into a rough rectangle before I start rolling it out.
Using a roller lightly dusted with flour, roll the dough out until it is approximately 2 feet and 1¼ feet (or 24 X 15 inches).
Spread the softened butter across the entire dough surface.
In a small bowl, mix the brown sugar and cinnamon together.
Spread the brown sugar and cinnamon mix over the butter, completely covering the dough. Keep in mind that the center of the cinnamon roll will be the edge where you start rolling, so if you like the center of your cinnamon rolls to be extra cinnamony, make sure your first fold includes a good portion of the cinnamon mix.
Roll the long end of the rectangle into a large log (like rolling up a sleeping bag sideways).
It may help to get the rolling going if you use a scraper or spatula to run underneath the dough.
Cut the cinnamon roll log into 12 equal slices. It should be about 2 inches per cinammon roll.
Place the rolls in a 9x13 dish, prepared with cooking spray.
Cover the dish and allow the cinnamon rolls to rise for about 30 minutes. Some recipes say to allow it to double, but once they look a little fluffier, they are good to bake.
Preheat the oven to 375°F.
Prior to baking, even pour the warm milk over the cinnamon rolls.
Bake for 22-25 minutes, until they are a light golden brown color.
