Preheat the oven to 350 degrees F (175 degrees C). Coat a 9x13 inch glass baking dish with cooking spray.
Combine pineapple, eggs, condensed milk, and sugar in a large bowl; mix well. Gently fold in bread cubes until well moistened; pour into the prepared baking dish.
Bake in the preheated oven until lightly golden on top, 25 to 30 minutes.
