Place the crushed candy canes into a small bowl.

Scoop the dough into rounded tablespoonfuls (#60 scoop) and lightly dip the tops into the crushed candy canes. Do not coat the entire cookie as it will just melt and become messy.
Place the cookie balls about 2 inches apart on the prepared baking sheet.
Bake cookies for about 10 minutes, or until set but soft in the center. Do not overbake.
Remove from the oven and sprinkle extra candy cane pieces on each cookie.
Allow to cool on the baking sheet for 5 minutes before removing to a cooling rack to cool completely.
