In a large bowl, cream together the butter and sugar until light and fluffy.

Add the eggs one at a time, beating well after each addition.

Stir in the drained crushed pineapple and cubed white bread.

Mix until all ingredients are well combined.

Grease a 1 1/2 quart casserole dish.

Pour the pineapple bread mixture into the prepared casserole dish.

Bake for 25 minutes, or until golden brown and set.

Let cool slightly before serving.
