Sweet gooey Pineapple Bars are rich, delicious, and full of tropical flavor. Using a box of cake mix for the crust makes this a quick and easy recipe. I have a few recipes on my site that use a boxed cake mix as an ingredient. Doctored cake mixes can be unbelievably good.
Prepare a 13×9-inch baking dish by spraying it with non-stick spray or lining it with parchment paper. Stir together cake mix, softened butter, and egg using a fork or pastry cutter. The dough may be a little crumbly, but it should press together to form a dough.

Spread the mixture evenly into the bottom of a prepared 13×9-inch baking dish. Press the dough into the bottom of the pan to form an even crust.

In a medium bowl, combine the sweetened condensed milk, crushed pineapple, pineapple juice, and lemon juice. Pour the pineapple mixture over the top of the cake mix.

Bake for 23 to 27 minutes. The bars may not seem quite done when you pull them from the oven. It’s fine, they should still be a little jiggly in the center when you remove them from the oven. They will continue to firm up and set as they cool. Cool completely before cutting into bars. Sprinkle with powdered sugar before serving, if desired. This is a great make-ahead dessert as the bars can be stored covered in the refrigerator for 4-5 days.
