Tropical Escape Soft Pineapple Crumble Bars

"The bars are soft, sweet, and the pineapple makes me feel like I’m on a tropical vacation. They're made in one bowl, without a mixer, and even though they’re a layered bar, they’re not fussy because the crust and topping are made from the same mixture to save time. There's an abundance of pineapple chunks in every bite, which are surrounded by a custardy, creamy filling. The bars are tender, delicate, and the firmer crust, in contrast with the soft, custardy interior, and the crumble topping make for so many great textures in each bite. If you keep them covered and as time passes, the topping becomes softer, less pebbley, and looks less like a true crumble topping due to the overall moisture level in the bars from the juicy pineapple. The bars are a perfect springtime or summery dessert and would be a great Easter or Mother's Day treat...."
