                While the cake is baking, place crushed pineapple with juice and granulated sugar into a small saucepan over medium heat. Stir constantly and bring to a boil, allowing the sugar to dissolve fully, approximately 2 to 3 minutes. Remove from heat and set aside.

                Once the cake has finished baking, leaving it hot in the pan, use a fork to poke holes evenly across the surface. Pour the warm pineapple mixture over the entire cake, spreading it evenly.

                In a large bowl, beat cream cheese and salted butter together using an electric mixer on medium speed until smooth, about 2 minutes.
