Start by preheating your oven to 350°F (175°C). Grease your baking dish with a little butter or non-stick spray. This ensures your delicious bake does not stick to the sides.

In a large bowl, mix the softened butter and granulated sugar together. Use a mixer or whisk until the mixture looks light and fluffy. This creates a sweet, creamy base for the bake.

Add the eggs to the butter mixture one at a time. Beat well after each egg is added to keep the texture smooth. The eggs help the bake rise and stay light.

Pour the entire can of crushed pineapple into the bowl. Do not drain the juice because it adds moisture and flavor. Stir gently with a spatula to combine everything evenly.

Cut your white bread slices into small, half-inch cubes. You can leave the crusts on for a bit of extra texture. The bread will soak up all the sweet pineapple juices.

Fold the bread cubes into the pineapple mixture carefully. Stir until all the bread pieces are fully coated. Add a pinch of salt and the ground cinnamon for a warm flavor.

Pour the mixture into your prepared 9x9 inch baking dish. Spread it out evenly so it cooks at the same rate. Place it in the center rack of your preheated oven.

Bake the dish for 40 to 45 minutes. The top should be a beautiful golden brown color. The center should be set but still moist and slightly bouncy to the touch.

Remove the dish from the oven and let it sit for five minutes. This helps the flavors settle and makes it easier to scoop. Serve it warm for the best taste.
