Preheat oven to 425°F. Mix 1 cup of the sour cream, 1 slice of the crumbled bacon (about 1 heaping tablespoon) and 1 tablespoon of the Seasoning in small bowl. Cover. Refrigerate until ready to serve.
Mix potatoes, milk, egg, remaining 1/2 cup sour cream, 3 slices crumbled bacon and 1 tablespoon Seasoning in large bowl until well blended. Shape the potato mixture, one tablespoon at a time, into balls. Press 1 cheese cube into the center of each potato ball, forming the potato mixture around the cheese to completely enclose it while shaping it into a “tot” shape.
Mix panko and melted butter in a shallow dish. Roll tots in panko mixture to coat. Place on foil-lined shallow baking pan.
Bake 20 to 25 minutes or until lightly browned and crisp, turning once. Serve with bacon sour cream mixture for dipping.
