Place a loaf pan into the freezer to chill.
In a large mixing bowl, use an electric mixer to beat the cold heavy cream until stiff peaks form.
Gently fold in the condensed milk, vanilla extract, and pinch of sea salt.
Stir in ¾ cup of the chopped peanut butter cups.
Remove the loaf pan from the freezer and pour half of the moose track ice cream mixture into the loaf pan.
Drizzle ¼ cup of chocolate sauce over the top of the ice cream. Repeat with the remaining ingredients and then use a butter knife to swirl the chocolate sauce into the ice cream.
Dot the top of the ice cream with the remaining peanut butter cups.
Place in the freezer and chill for 6-8 hours in a level spot until the ice cream is set. Serve as is or scoop into an ice cream cone, enjoy!
