Melt chocolate chips over low heat using a double-boiler. To make a double-boiler with a pot and a metal bowl, fill a medium pot with approx 1 inch of water and set the metal bowl over the pot. The bottom of the bowl shouldn’t touch the water. Stir the chocolate chips intermittently as they melt.
Add broken pretzels and candycane to the bowl of melted chocolate and stir.
Pour onto a baking tray covered in parchment paper. Sprinkle more crushed candy cane on top of the chocolate mixture.
Refrigerate for 30min or until chocolate is hard.
Break bark into pieces and enjoy. I find it’s best to keep the bark refrigerated.
