Preheat the waffle maker. Set on a lower temperature.
When ready, spray the waffle maker with nonstick cooking spray (top & bottom).
Place 2-3 cinnamon rolls onto the grates keeping them close together.
Close lid and gently press down while it cooks (don't press too hard.)
Cooking times will vary depending on your waffle maker but it generally takes about 1 1/2 to 2 minutes.
After they are finished, spread on the icing that comes with the cinnamon rolls.

Notes
Don't let your waffle maker get too hot or else you will have a burnt outside while the inside of the cinnamon roll is still raw.
Even if your waffle maker is "nonstick" you will still want to spray the grates with nonstick cooking spray.
This works with any type of refrigerated cinnamon rolls. If you purchase "jumbo" cinnamon rolls, you may only to be able to do one or two at a time. Just don't overfill the waffle maker.
