Overfilling your cinnamon rolls
Cinnamon rolls are notoriously easy to overfill. To avoid leaking butter and brown sugar onto your baking sheet (which could burn and set off your kitchen smoke alarm), watch how much cinnamon sugar filling you add to the rolls. As a general rule, you should always leave at least an inch of space between your filling and the sides of the rolled dough. Only a light sprinkle of the cinnamon sugar filling is required in the dough.
Another tip for avoiding overfilling your cinnamon rolls is to roll them as tightly as possible. This will keep the sugar from falling into the dough and onto the baking sheet through the cracks. Pinch along the seam of the dough after rolling it to keep the rolls from unraveling when cutting.
