Sweet Potato Casserole - cooking recipe

Ingredients

1 (1 lb.) can sweet potatoes, drained or 2 lb. cooked, fresh sweet potatoes (I use fresh)
1/2 c. sugar
4 Tbsp. soft butter
1 tsp. salt
1 tsp. vanilla
1 c. pecans, broken
1/2 stick butter, softened
1/2 c. brown sugar
3/4 c. crushed cornflakes

Preparation

Put potatoes, 1/2 cup sugar, 4 tablespoons butter, salt and vanilla in a mixer bowl.
Beat until mixture is very light and fluffy (this is the secret of the dish).
Pile mixture into a greased 2-quart casserole.
Mix together pecans, 1/2 stick butter, 1/2 cup brown sugar and cornflakes to make a crumbly topping. Spread over sweet potato mixture.
Bake at 350\u00b0 for about 45 minutes or until mixture is hot and topping browned.
