Coconut Grapefruit Cookie Dough Bars

Though my kids did not really like them a lot, I guess it's grapefruit content, grown ups found them lovely:) These frosted cookies are rich, with thick layer of cream on top, but that is why they are cut into small wedges. I think that combination of coconut cookie and slightly tart and very fragrant grapefruit icing makes them really interesting and tasty.
Those, who don't appreciate a lot of cream could use slightly larger baking dish, so that the cream layer would be thinner. In such case, baking time would be shorter.

1,5 cup AP flour
