Kathi's Sweet Potato Souffle'

My sister Kathi makes this every year for Thanksgiving. I don't really like sweet potatoes or yams but this dish is really delicious.

3 cups yams, baked or canned
2 eggs
1/2 cup sugar
1 tsp. vanilla
1/2 cup butter, melted

Beat all together with mixer, put in a casserole dish.

Top with:
1/2 cup brown sugar
2 Tbsp. flour
3 Tbsp. butter

Mix together, sprinkle on top of yams, then sprinkle with 1/2 cup of chopped pecans. Bake at 350* for 30 minutes.
