Preheat your oven to 350 degrees Fahrenheit.
Roll your cookie dough into 1" balls and place about 2-3 inches apart on parchment paper-lined baking sheet. Bake according to package directions (about 12 minutes).
Let cool on a rack for a few minutes (they'll cool pretty fast). Meanwhile, place your frosting in a piping bag with Wilton tip #47 (or similarly wide and flat shaped tip). You can easily use a Ziploc bag if you don't have a piping bag. Frost in back-and-forth sheets to create the mummy look. Give the mummies some googly eyes. Eat up!
