Peel sweet potatoes while hot. Mash well. Add well beaten bananas, hot cream, butter, and salt. Place in baking dish. Bake at 350 degrees F for 30 minutes. Cover with marshmallows and return to oven until they are brown, about 5 minutes more.

Prepare potatoes according to package directions. Beat in cheese, sour cream, yolks, chives and celery salt. Beat whites until stiff peaks form; fold whites and parsley into potatoes.
