Preheat your oven to 350F.
Line 2-3 baking sheets with parchment paper and set aside.
Set up your decoration station: pour the powdered sugar and the candy cane powder into two separate small bowls. Place bowls near your prepared baking sheets.
Remove the cookie dough from the freezer. Using a cookie/ice cream scoop, scoop dough and release directly into the little bowl(s) filled with powdered sugar and/or candy cane powder.
Coat the the dough drops liberally with powder until completely covered, then roll the decorated dough between your hands to form balls, like you would make a meatball.
Place decorated dough balls on the prepared baking sheets. I was able to fit 8 -10 cookies per sheet.
Bake cookies at 350F for 10 minutes, or until the tops have crackled open, the cookies have poofed up, and the edges of the cookies are firm to the touch.
Remove cookies from oven. Immediately sprinkle the hot cookies with crushed candy cane pieces, if desired. Let cookies rest 1-2 minutes, then carefully transfer to a cooling rack.
Peppermint Chocolate Crinkle Cookies will continue to harden as they cool. Let cool completely before serving.
