rum with yellow cake or pound cake and choco ganache or frosting is a good combo, especially if you bake it into the cake and mix it in the ganache/frosting.

use malibu rum if you want the coconut vibe and bake the cake with coconut milk instead of milk...it's soooo good.

ask your bakery to make you all some rum sheetcake if you don't want to bake yourself.

smoke some weed with all that and you're all set.
