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. Heat 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 - In separate microwave-safe bowls, melt the white chocolate chips and colored candy melts. Heat 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 effect without over-mixing.
06 - Immediately scatter mini candy-coated chocolates, candy eyes, and Halloween sprinkles evenly over the warm bark. Press gently to ensure toppings adhere to the chocolate.
07 - Allow the bark to set at room temperature for 1-2 hours, or refrigerate for 10-15 minutes until firm and completely hardened.
08 - Once fully set, break the bark into irregular, bite-sized pieces by hand. Serve immediately or store in an airtight container.
