Make sure that you are using rapid rise instant yeast and not active yeast (slow rise). This will make your cinnamon roll dough to sticky to roll.
Use plastic wrap to help shape and roll the cinnamon rolls. You can use just your hand but this will be a tough dough to roll due to its stickiness.
Feel free to dust off any excess cornstarch from the rolls using a bating brush or a silicone brush that you have available.
