Pineapple Chewy Bars

Preparation
Preheat oven to 350 degrees F and grease a 9×13 baking dish.
In a large bowl, mix together the sugar, eggs, and 20oz can of pineapple with juice. Once combined, add the flour, baking soda, and salt.
Transfer batter to the prepared baking dish and bake for 43-45 minutes.
As cake bakes, prepare the frosting: add all frosting ingredients to a small saucepan. While continuously stirring, cook over medium heat for 8-10 minutes or until thickened.
Once cooled, use a fork to poke holes all over the top of the cake, then pour frosting over the top. Chill until ready to serve.
