Whisk heavy cream, sweetened condensed milk, and salt together in a bowl
Mix in the crushed cookies pieces into the ice cream base
Pour the ice cream base onto a metal sheet pan or rimmed baking sheet. The mixture should just cover the bottom of the pan
Place the sheet, laying flat, into the freezer until the mixture is completely frozen
Once frozen, remove the sheet pan from the freezer and place on a flat surface. The sheet should be horizontal, longer side facing toward you
Using a metal spatula, work the edge under the ice cream, carefully pushing forward and rolling the ice cream into itself to form a roll.
Use tongs to transfer the rolled ice cream into a serving dish
Repeat process for the remaining ice cream on the pan
Sprinkle additional crushed cookies on top
