If you're not a peppermint fan just scale back or omit the peppermint extract and or candy cane.
To store the cookie dough roll out into a log, wrap well with plastic wrap then place in a sealable plastic bag and freeze.
pressing the cookie balls into the crushed candy cane is the easiest and neatest way to apply it.
You can totally add nuts to this recipe for some amazing crunch. I would suggest macadamia, pecans, or walnuts.
