Rum Cupcake?

So today I was at a friends and she was helping me with the blog. Well she is having a house warming party and we started talking about cupcake flavors, we all started taking about rum cupcakes.. Then I thought coconut run!  do pineapple cake with coconut rum frosting, or coconut rum cake with pineapple frost. I think pineapple as the cake then the rum frosting.. it will be over 21 cupcake!  So we are thinking of trying these a great way to end the summer!

Here is photo of idea what I can do :)
