Line a cookie sheet with parchment paper and set aside.

Place semi-sweet chocolate chips in a medium-sized microwave-safe bowl. Heat for one minute, then stir. Heat for an additional 30 seconds and stir again. Continue to microwave and stir at 30-minute intervals until fully melted and smooth. Pour onto prepared baking sheet and use a spatula to create a thin, even layer. Place in refrigerator and harden for about 20 minutes.

Place white chocolate chips and peppermint extract into the double boiler. Keep on low heat, until white chocolate is almost melted. Stir 1/2 cup of crushed candy cane into melted white chocolate. Remove from heat and pour an even layer over the hardened semi-sweet chocolate. Sprinkle with remaining 1/2 cup crushed candy canes. Place in refrigerator to set for about 45 minutes.

Once completely hardened, remove from cookie sheet and break into pieces. Enjoy!
