Freeze a pack of milk in the freezer. If one pack is too much, pour some milk into a ziplock bag, spread it flat, and freeze.

Place Oreo cookies in a plastic bag and crush them with a rolling pin. Leave one or two cookies aside for decoration.

Take out the frozen milk and twist it slightly by hand. If it's too hard, let it thaw slightly before use.

Place the frozen milk into a serving bowl.

Layer the crushed Oreo cookies on top of the frozen milk and drizzle condensed milk to taste. Decorate with the reserved Oreo cookies.
