Whisk together cream, milk, sugar, vanilla, and salt. Pour into your ice cream maker and freeze according to the manufacturer's instructions.
While it churns, chop the candy bars into uniform ¼ inch pieces.
Scoop about a third of the ice cream into an 8″ pan or loaf pan, then scatter about a ½ cup of the candy bar pieces over the ice cream. Drizzle with caramel sauce and hot fudge. Repeat this step twice more.
Place in the freezer and allow the ice cream to harden for at least 2-3 hours before serving.
