Divide the batter evenly between two 8-inch cake pans. Bake for 35 to 50 minutes, or until a toothpick inserted into the cake comes out clean. Take the cakes out of the oven and allow them to cool for 10 minutes.

In a mixing bowl using an electric mixer, cream the butter and cream cheese together for 3 minutes on medium speed. Add the vanilla and salt, and then mix for 1 minute on medium speed. Slowly add the powdered sugar into the mixture on low speed. When all of the sugar is incorporated, increase the speed to medium and then mix for 3 minutes. Add whipping cream 1 teaspoon at a time if you wish to thin the frosting consistency, or add powdered sugar 1/4 cup at a time to thicken the frosting consistency.

Put the first cake layer onto your serving platter. Fill a large Ziploc bag with some of the frosting. Snip the tip of the bag off, and then pipe a continuous ring of frosting around the perimeter of the bottom cake layer. Spoon the pineapple rum filling inside of the ring of frosting, making sure to spread it out evenly with the back of the spoon. Place the top cake layer on top of the pineapple filling. Frost the entire cake with the remaining cream cheese frosting.
