Line your baking sheet with parchment paper or a silicone mat, ensuring a smooth, flat surface for your chocolate.
Place the dark chocolate in a double boiler or microwave-safe bowl and melt in short bursts, stirring until smooth and glossy. The chocolate should be fully melted and fragrant.
Pour the melted chocolate onto the prepared baking sheet, using a spatula to spread it evenly into a thin layer, about 1/4 inch thick. You’ll hear a gentle sizzle as the chocolate settles.
Sprinkle the candied nuts, dried fruit, and crushed cookies evenly over the warm chocolate, pressing them lightly into the surface so they adhere well.
Add a few sprinkles or edible glitter on top for a festive shimmer, and finish with a tiny pinch of sea salt flakes to enhance all the flavors.
Let the bark cool at room temperature until completely set and firm, about 2 hours. For quicker results, refrigerate it for about 30 minutes until solid.
Once hardened, break the bark into irregular shards using a knife or break-apart tool, revealing a glossy, textured surface with colorful toppings.
Enjoy your homemade Halloween chocolate bark, perfect for sharing or gifting at your spooky celebration!
