Wash and dry potatoes; prick with a fork and bake until tender, about 60 to 75 minutes. Set aside until cool enough to handle; then, halve potatoes and use a melon baller to scoop out the pulp.
In a large bowl, mix potatoes with 1 stick of the butter, the sour cream, heavy cream, salt and pepper; mash together.

Butter a 9- x 13-inch dish with the remaining 2 Tbsp butter. Pour mixture into baking dish and top with remaining shredded cheese.
Reduce oven heat to 375ºF. Bake casserole until bubbling around edges, and the cheese is melted on top and lightly browned, about 35 to 40 minutes. Serve hot.
