Bake 4 sweet potatoes in oven until soft (375 degrees, about an hour or more) (or use approximately 2 cups of canned)
Or boil for 12 minutes, with just enough water to cover

Mash potatoes with mixer,

Mix in 1 Cup sugar

1/2 Cup flour

1 large can evaporated milk

1  sticks of margarine or butter, melted

2 beaten eggs

Put in large 9 x 13 baking dish, and top with crushed ( not pulverized) corn flakes and bake at 350 degrees for about 30- to 40 minutes, then top with small marshmallows and bake until marshmallows are golden brown.



Can be made a day ahead, just mix all, put in pan, refrigerate and then bake shortly before eating.
