Start by placing 12 oz of white chocolate in a microwave-safe bowl. Heat in the microwave in 30-second increments, stirring after each interval until smooth and fully melted, about 1-2 minutes.

While the chocolate is melting, line a baking sheet with parchment paper to prevent sticking. Set it aside.

Carefully pour the melted white chocolate onto the lined baking sheet and spread it evenly into a rectangle about 1/4 inch thick.

While the chocolate is still warm, evenly sprinkle crushed Halloween Oreos, Reese’s Pieces, festive sprinkles, and eyeball candies on top.

Place the baking sheet in the refrigerator and chill for 1 hour, until the surface is firm to the touch.

Once chilled, gently lift the edges of the parchment paper to detach the bark, then break it into irregular pieces.
