Best Pecan Yams

4 cups cooked and mashed yams/sweet potatoes
1 cup sugar
1/2 cup butter, melted
2 eggs
1 teaspoon vanilla

Topping:
1 cup brown sugar
1/3 cup flour
1/3 cup butter, melted
1 cup chopped pecans (I don't ever add these)

Combine yams, sugar, 1/2 cup melted butter, eggs and vanilla.  Mix well and spread into a greased 9 x 13 glass dish.  Combine brown sugar and flour, mix well.  Stir in 1/2 cup melted butter and nuts.  Crumble over the top.  Bake for 30-45 minutes at 350 degrees or until set.

Delicious!
