Here's one way.  This deletes the _PARENT object:

    use Data::Dumper;

    my $stash = $context->stash->clone();
    delete($stash->{_PARENT});
    my $d = Data::Dumper->new([$stash], [qw(*Stash)]);
    $d->Indent(1);
    print $d->Dump;

You could put this in a plugin, or make it a code ref in your call
to process, eg:

    use Template;
    use Data::Dumper;

    my $tt = Template->new();
    $tt->process(\*DATA, {
            dumpStash => sub {
                my $stash = $tt->context->stash->clone();
                delete($stash->{_PARENT});
                my $d = Data::Dumper->new([$stash], [qw(*Stash)]);
                $d->Indent(1);
                return $d->Dump;
            },
        }) || die $tt->error();

    __DATA__
    [% dumpStash %]
