In a loaf pan, drop alternate scoops of ice cream in a random pattern to cover the bottom of the pan. Place a sheet of parchment over the ice cream and, using another loaf pan or your hands, press the scoops into a flat layer. Remove the parchment.

Scoop another alternating layer of ice cream onto the top of the flattened layer and flatten again. Repeat the process to make a third and final layer.

Place the loaf pan into the freezer to harden.

Before serving, remove ice cream from the freezer and let it soften for a few minutes. Drag an ice cream scoop across the loaf pan lengthwise to marble the ice cream into the scoop. Place scoops in a dish or onto ice cream cones.
