Preheat the oven to 175 F. Line a baking sheet with parchment paper. A 9x13 size (quarter sheet) small baking sheet is the perfect size, if yours is larger just melt the chocolate bars in the middle of the baking sheet.
Crush the Oreos and candy canes.
Add the chocolate bars to the baking sheet. Bake for 5-6 minutes until the chocolate is JUST soft, it burns and gets grainy quickly.
Remove the softened chocolate bars from the oven. Make swirls in the chocolate to blend the colors together.
Sprinkle the crushed Oreos and crushed candy canes over the chocolate as desired, going as light or heavy as you want.
Place the baking sheet in the fridge for 1-2 hours or until set. Enjoy!
You can double the recipe and use a large baking sheet. This is a perfect size for gifting.
The bark lasts about 2 weeks, you can store it in the fridge or freeze it for up to 2 months.
