In a large bowl or the bowl of a stand mixer, combine the sweetened condensed milk and whipping cream and whip on medium speed until it thickens to a fluffy, cloud-like mixture. Fold in the crushed candy canes and sandwich cookies until well combined. Spread the mixture out into a 9×4″ loaf pan or freezer-safe dish and cover with aluminum foil to protect. Allow to freeze until solid, about 6 hours or overnight. Enjoy!
