Pair cookies so that they are closely matching in size; turn one cookie from each pair upside down
Place a scoop of ice cream (about ⅓ cup) on top of an upside down cookie; press matching cookie down to form an ice cream sandwich; repeat with a few ice cream sandwiches and then place in in the freezer (in a ziplock bag or tupperware) while making remaining ice cream sandwiches; repeat until finished
Store ice cream sandwiches in a ziplock bag or airtight container in freezer up to one month; keep frozen until serving
