07 - Scoop tablespoon-sized balls of dough and place onto prepared baking sheets, spacing them about 2 inches apart.
08 - Sprinkle additional crushed peppermint on top of dough balls if desired.

10 - Allow cookies to cool on the baking sheet for 5 minutes before transferring to a wire cooling rack to cool completely.
