Preheat the oven to 350°F (175°C) and grease a baking dish with butter or nonstick spray.
Beat the butter and sugar together in a mixing bowl until the mixture becomes light and fluffy.
Add the eggs gradually, mixing well after each addition to ensure a smooth consistency.
Gently fold in the crushed pineapple with its juice, the drained pineapple tidbits, and the bread cubes until everything is evenly combined.
Transfer the mixture into the prepared baking dish and spread it out evenly. Sprinkle the top with brown sugar and cinnamon or pumpkin spice.
