Melting Chocolate Puddings from frozen

Hi Lindsey . I want to make the Melting Chocolate Puddings for Christmas but as my grandchildren and a teetotaller will be eating them , don't want to put the brandy in. Should I just leave this out and/or replace with other liquid to get the consistency right ? If so what liquid ? Also how do I cook them as I'll be freezing them ? Take them out the night before to defrost or cook straight from freezer - for how long etc ? Many thanks . Merry Christmas. Jenny
