Preheat oven to 375 degrees. Cut out a piece of parchment paper to line your 14-inch cast iron skillet. Spray the bottom of the skillet lightly with oil and place the parchment paper over the oil, pressing down to secure it to the bottom of the skillet.
Pour your sticky pecan topping into the skillet, spreading it evenly all over the bottom, and set aside.
Once the dough has finished rising, lightly flour the countertop and roll the dough out into a 10"x16" rectangle. Scoop the cinnamon filling into the center of the rectangle and evenly spread it all over the top of the dough. Leave a 1/2" seam bare of the filling on the long side of the dough furthest from you.
Start rolling the dough on the long side closest to you (the side on which you took the cinnamon filling all the way to the edge) and roll it all the way up to the edge you left bare.
Using a serrated bread knife, cut off the smaller ends of the log to even it up, and then cut it into 11 equal pieces. (12 pieces if you are using a 9x13 baking pan)
Place each roll in the skillet over the sticky pecan topping. Start with three in the middle of the pan, and then go around the outside with the remaining rolls. It's okay for them to have space between them, they will grow together as they rise and bake. Cover them with plastic wrap and allow them to rise for another 25-35 minutes.
After they are done rising, place them on the middle rack of the oven and bake for 30 minutes, or until golden brown, or until the internal temperature reaches 185 degrees.
Before they are done baking, line another baking tray with parchment paper or a large cutting board. (Something with edges is excellent, though, so the caramel doesn't ooze everywhere!)
Once the rolls are done baking, remove them from the oven and let them cool for 5 minutes. After 5 minutes, use hot pads and quickly flip the pan over onto a large cutting board or baking sheet. If you used a 9x13 baking pan, place the baking sheet with the parchment paper over the top of the pan, and then, flipping it over together, turn the rolls out onto the sheet to finish cooling. You must get them out of the skillet/baking pan before they are fully cool, or the caramelized sugar will harden, sticking them to the skillet/pan.
Serve warm with a cup of coffee and enjoy!
