I am making a pina colada cake with a coconut cream filling...what kind of frosting would you suggest. I was thinking maybe buttercream but replacing the flavorings with maybe rum extract and pineapple or something...Help please i am clue less

yes, buttercream with pineapple flavoring OR just plain old, whipped cream icing to take out any richness! You can add pineapple flavoring to that also. ALSO poke holes in cake when done and put sugar rum syrup inside,,not too much..but some to add flavor to your cake! Yummy
