This "some assembly required" recipe can be made to fit your mood and timeframes.
Arrange cookies on a platter. Remove ice cream from the freezer at least 5 to 10 minutes before serving so that ice cream is easily scooped. Place ice cream in a ice bucket with ice in the bottom to keep it cool. Serve family style at the table so that guests can make their on "sandwiches". To assemble, use a cookie for the bottom, scoop the desired amount of ice cream as the filling then place a cookie on top.
If you are short on time, buy your favorite cookies and vanilla ice cream. If you have extra time, make a batch of your own favorite cookies.
