Line a baking sheet with parchment paper to prevent sticking and make cleanup easier.
Place the chopped chocolate in a heatproof bowl. Melt it gently using a double boiler or microwave in 30-second bursts, stirring in between, until smooth and glossy.
Pour the melted chocolate onto the prepared parchment-lined sheet. Use a spatula to spread it evenly into an approximate 1/4-inch thick layer, smoothing out any peaks or rough spots.
Sprinkle your spooky toppings—candies, edible glitter, or candy eyes—over the warm chocolate. Press them lightly so they adhere well.
Optionally, sprinkle a pinch of sea salt or chili flakes over the top for an extra flavor kick.
Allow the bark to set at room temperature for about 30 minutes, or place it in the fridge for 15-20 minutes until it’s firm to the touch.
Once fully hardened, break the chocolate into rustic, irregular pieces using your hands or a sharp knife.
Enjoy your spooky, shiny Halloween bark immediately or store it in an airtight container for up to a week.
