Beat together the mascarpone, cream, sugar, orange zest and juice until smooth. spoon into a piping bag with a plain or fluted nozzle (or into a plastic sandwich bag and trim the corner to use as a piping bag). Pipe a good blob onto the underside of half of the cookies and sandwich the remaining cookies on top. freeze for an hour or until the filling is firm. Serve straight from the freezer.
