Line a small baking sheet with parchment paper. Set aside.
Place the white chocolate and ½ teaspoon of coconut oil in a microwave-safe bowl and heat, stirring every 30 seconds until melted. Stir in ¼ teaspoon peppermint extract.
12 ounces white chocolate, ¾ teaspoon coconut oil, ½ teaspoon peppermint extract
Pour ½ of the white chocolate mixture into the prepared baking dish, and smooth into an even layer with a spatula.
Place in the refrigerator for 10-15 minutes or until almost completely set.
Place the semi-sweet chocolate and remaining ¼ teaspoon coconut oil in a heat-proof bowl, and heat, stirring every 30 seconds until melted. Stir in ¼ teaspoon of peppermint extract.
6 ounces semisweet chocolate
Pour the semi-sweet chocolate over the white chocolate and smooth into an even thin layer.
Refrigerate for another 10-15 minutes or until almost set.
While the chocolate is setting up, crush the candy canes by placing them in a Ziplock bag and using a rolling pin to break them up.
3 candy canes
Re-melt the remaining white chocolate if needed. Pour over the semi-sweet chocolate and smooth into an even layer. Top with a generous sprinkle of the crushed candy canes.
Refrigerate for at least another 30 minutes or until the bark is completely set.
Once set, remove from the pan and peel off the parchment paper. Slice or break into pieces as small or as large as you'd like.
