Line a 23 cm x 23 cm baking dish with parchment paper, allowing overhang on two sides for easy removal. Set aside.
02 -
In a large food processor, pulse Oreo cookies until finely ground. Transfer crumbs to a large mixing bowl.
03 -
Pour melted milk chocolate and kosher salt over the crushed Oreos. Mix thoroughly until the texture resembles wet sand.
04 -
Press half of the Oreo-chocolate mixture (approximately 1.5 cups or 225 g) firmly into the base of the prepared dish using a flat measuring cup or spatula to ensure an even layer. Refrigerate the remaining mixture.
05 -
Scoop the cookies & cream ice cream onto the Oreo base. With gloved hands or a stiff spatula, gently spread and press the ice cream evenly to each edge. Freeze for 1–2 hours, or until the ice cream is firm.
06 -
Evenly distribute and gently press the reserved Oreo mixture over the firm ice cream layer to form a cohesive top crust.
07 -
Return the dish to the freezer and chill for at least 8 hours or overnight, until completely set.

Using the parchment overhang, lift the chilled slab from the dish and transfer to a cutting board. Cut into 9 equal squares and serve immediately, or store as directed.
