Method: Chop up the Coffee Crisp bars. Whip cream until stiff peaks form. Fold in condensed milk until fully combined, then fold in coffee liquor. Fold in the ¾ of the Coffee Crisp pieces. Transfer to a 9"-x-5” pan and top with remaining Coffee Crisp pieces. Freeze until firm, at least 5 hours. Let soften 10 minutes before serving.
