Line the bottom of the baking pan with parchment paper.
In a small saucepan, over medium heat, melt the semi-sweet chocolate until smooth, stirring frequently. If using a microwave, microwave at 20-30 second intervals, stirring in between. If chocolate is too thick, add 1-2 tsp of vegetable shortening to thin it out.
Pour melted chocolate onto the prepared baking pan, spreading it evenly. Place the pan in the freezer for 10 minutes.
Repeat the melting process with the white chocolate chips. Add peppermint extract and if chocolate is too thick, add 1-2 tsp of vegetable shortening to thin out the chocoalte.
Pour melted white chocolate onto the semi-sweet chocolate layer, spreading it evenly.
Sprinkle crushed candy canes generously over the white chocolate layer. Gently press down to make sure they adhere to the chocolate.
Place in the refrigerator to chill for about 30 minutes or place in the freezer for 15 minutes to speed up the process.
Once candy is set, remove parchment paper and break or cut into pieces.
Serve and enjoy!
