01 - Line a baking sheet with parchment paper to prevent sticking and ensure easy removal.
02 - Place semisweet chocolate chips in a microwave-safe bowl. Microwave in 30-second intervals, stirring thoroughly after each interval, until completely smooth and melted.
03 - Pour the melted semisweet chocolate onto the prepared baking sheet. Spread evenly using a spatula to form a rectangle approximately 1/4 inch thick.
04 - Melt white chocolate chips and assorted candy melts in separate microwave-safe bowls. Heat in 20-second intervals, stirring between each, until smooth and pourable.
05 - Drop spoonfuls of melted white chocolate and colorful candy melts over the dark chocolate base. Use a toothpick or skewer to gently swirl the colors together, creating a marbled pattern throughout the bark.
06 - Immediately sprinkle candy-coated chocolates, candy eyes, and Halloween sprinkles over the warm chocolate. Press gently to ensure toppings adhere to the surface.
07 - Allow the bark to set at room temperature for 1-2 hours, or refrigerate for 10-15 minutes until completely firm and solid.
08 - Once fully set, break the bark into irregular, rustic-sized pieces. Arrange on a serving platter and enjoy.
