Line a 9x13-inch baking sheet with parchment paper and set it aside.

Place the cookies & cream chocolate into a microwave-safe bowl. Microwave in 30-second intervals, stirring well between each, until the chocolate is fully melted and smooth.

Pour the melted chocolate onto the prepared baking sheet and spread it into an even layer using a spatula.

Immediately sprinkle the crushed Oreo cookies evenly over the chocolate. Add the gummy worms on top, gently pressing them into the chocolate so they stick. Add larger Oreo pieces if you’d like a little extra crunch.

Let the bark set at room temperature for about 20 minutes, or until fully hardened.

Once the bark is set, break or cut it into pieces and serve.
