Charline's Sweet Potato Casserole is a very excellent recipe and this is now going to be a holiday standard. I like things sweet, but I cut the sugar in half and only used 1 stick of butter for the casserole and 1/2 stick for the topping. 

Ingredients of Charline's Sweet Potato Casserole

4 cups sweet potatoes, peeled and cubed

2 cups white sugar

4 eggs, beaten

3/4 cup margarine, melted

1 cup evaporated milk

1 teaspoon ground nutmeg

1 teaspoon ground cinnamon

2 cups miniature marshmallows

1 cup flaked coconut

1 1/2 cups crushed cornflakes cereal

1/2 cup packed brown sugar

1 cup chopped pecans

3/4 cup margarine, melted

Preparation of Charline's Sweet Potato Casserole

Preheat oven to 400 degrees F (200 degrees C). Prepare a 9x13 inch baking dish with butter.

In a large bowl, mash the sweet potatoes. Mix together with sugar, eggs, 3/4 cup margarine, evaporated milk, nutmeg, cinnamon, marshmallows and coconut. 

Scoop the mixture into the baking dish.

Bake 20 minutes in the preheated oven, or until sweet potatoes are tender.

In a small bowl, mix the crushed cornflakes, brown sugar, pecans and remaining 3/4 cup margarine. Spread the topping over the baked casserole.

Return the casserole to the 400 degrees F (200 degrees C) oven and bake an additional 10 minutes.
