Yes, but it will be denser. Air is lost as it melts slightly as it freezes. Freeze it inside a piping bag fitted with a star piping tip or in a container. Defrost for about 20 to 30 minutes to make it easier to pipe or scoop. Alternatively, scoop or pipe the dole whip into individual portions into a disposable cup. Freeze on a sheet pan until ready to serve. Cover the cups if not serving within one day.
