I make this one every Thanksgiving and Christmas. Boil and mash three large sweet potatoes with 3 tbs. butter, 1/3 cup carnation evaporated milk, 1/3 cup brown sugar and 1/4 cup white sugar, 1tsp. vanilla and 1 tsp cinnamon. Mix well and spread in a nine inch baking dish. Top with crunch made with one cup flour, 1/2 cup brown sugar, 3/4 cup butter and 1 cup ground pecans cut up fine. Bake for 15 minutes at 350.
