01 - Line a baking sheet with parchment paper to prevent sticking and ensure easy removal of the finished bark.
02 - Place semisweet chocolate chips in a microwave-safe bowl. Microwave in 30-second intervals, stirring thoroughly after each interval, until completely smooth and fully melted.
03 - Pour the melted semisweet chocolate onto the prepared baking sheet. Spread evenly using a rubber spatula to form a rectangle approximately 1/4 inch thick.
04 - In separate microwave-safe bowls, melt the white chocolate chips and colored candy melts. Microwave each in 20-second intervals, stirring between intervals, until smooth and fully melted.
05 - Drop spoonfuls of the melted white chocolate and colorful candy melts randomly over the dark chocolate base. Use a toothpick or skewer to gently swirl the colors together, creating a marbled pattern without over-mixing.
06 - Immediately sprinkle the candy-coated chocolates, candy eyes, and Halloween sprinkles evenly over the warm chocolate. Press lightly to ensure toppings adhere to the surface.
07 - Allow the bark to set at room temperature for approximately 30 minutes, or refrigerate for 10–15 minutes until completely firm and no longer shiny.
08 - Once fully set, break the bark into irregular, rustic-sized pieces. Arrange on a serving platter or store in an airtight container.
