Preheat oven to 350 degrees F. Place parchment paper on a baking sheet.
Open cinnamon roll can and place cinnamon rolls on baking sheet. Bake for 12 minutes.
Remove and let cool.
Ice with black cookie icing making a spider web. Place eyes on top of cinnamon roll.
Notes
Let the cinnamon rolls cool completely before decorating so the icing doesn't melt.
For extra contrast, spread the white icing from the can on first, then pipe the black web on top.
