Smear softened butter all over the bottom of a baking dish. Slice potatoes as uniformly as possible.
Place enough potatoes in the pan to cover the bottom. Add some of the bacon, ham and corn on top of the potatoes. Repeat this until you’ve created a few layers and have used all the potatoes, ham, corn and bacon.
