How to Make It
Line a loaf pan with parchment, leaving an overhang. Press 1½ pints softened vanilla ice cream into the pan, top with 20 chopped mini peanut butter cups, another 1½ pints vanilla ice cream, and ¾ cup broken pretzels. Freeze until firm, at least 1 hour and up to 2 days.
To serve, remove from pan and slice.
