Preheat oven to 375 degrees.
Slice cooled, baked potatoes in half, lengthwise. Scoop the flesh out of the skins, getting as much as you can, and place in a large bowl.
Add butter, sour cream, heavy cream, salt, pepper and eggs and mash until chunky-smooth.
Add bacon, 1/2 of the cheese, and green onions and mix well.
Pour mixture into a buttered casserole dish. Top with remaining cheese and bake for 35-40 minutes or until brown and bubbly.
