Not giving your cinnamon rolls enough space in the oven

Cinnamon rolls are particularly elastic and stretchy. The dough will expand and cover more space than you think as it bakes. If you want perfectly baked cinnamon rolls, allow enough room for the rolls to expand during baking. When cinnamon rolls erupt like miniature volcanoes, it's a sign that you need more room. The resulting volcano texture will be dense and underbaked in the center and overbaked on the outer rings.

If you use a pull-apart cinnamon roll recipe, you should leave at least an inch of space on all sides of the rolls. On a baking sheet, stand-alone cinnamon rolls can take up to 2 inches of space on all sides. The resulting cinnamon rolls will be perfect, evenly cooked, and, most importantly, delicious.
