Heat your oven to 375 degrees. Wash and dry the potatoes, and then rub them with butter and sprinkle with salt. Place on a baking sheet and bake for one hour.

After one hour, remove the potatoes from the oven. They should be soft on the inside - if not you can let them cook a little longer. Slice the potatoes in half, and scoop out about ⅔ of the inside. You want a layer of potato to be left on the skin.

Combine the scooped out potato, 1 tablespoon butter, ½ cup sour cream, half the cheddar cheese, and cream cheese. Mash to combine.

Then add mix in salt and pepper and some extra sour cream. You want to add a little too much sour cream.

Scoop the mashed potatoes back into the potato skins. Top with the remaining cheese and butter.

Bake for another 25 minutes, and then serve right away. Sprinkle with bacon or crispy prosciutto if you want.
