Pop your rolls into the oven and bake according to the tube's instructions, or your favorite homemade recipe if you're starting from scratch. If your tube only gives you 5 rolls, tuck a ramekin into the empty spot in your baking dish so every roll bakes up round and even. Let the rolls cool completely before you touch the icing step.
Warm icing runs everywhere, so pour it into a bowl and beat in the powdered sugar with your hand mixer. You want it thick enough to hold a piped line but still soft enough to squeeze through a bag. This little tweak is honestly the cinnamon roll recipe secret ingredient step that makes the mummy design actually work.
Fill your piping bag fitted with a basketweave tip, or just snip the corner off a zip-top bag if you don't have one. Pipe messy, crisscrossing lines across each roll, leaving some cinnamon roll peeking through so it still reads as a "wrapped" mummy instead of a solid blob of icing.
While the icing is still sticky, press two candy eyeballs onto each roll so they stay put as everything firms up. Give the rolls a few minutes to set before serving, or dig in right away if you can't wait. Either way, they're ready to spook and impress
