Freeze the milk in the freezer. Use a ziplock bag to flatten the milk for quicker freezing.

Crush the Oreo cookies into chunks. Reserve 1-2 cookies for decoration.

Take out the frozen milk and gently twist or break it into flakes. If too hard, let it thaw slightly before breaking.

Place the milk flakes into a serving bowl.

Layer the crushed Oreos on top of the milk flakes and drizzle condensed milk over them.
