3 c. sweet potatoes, mashed
1 stick butter
1 1/2 c. sugar
1 tsp. vanilla
1/2 c. milk
3 eggs

Melt butter and add rest of ingredients to cooked potatoes. Beat on low speed of mixer until creamy. Put into well-greased (I use Pam) casserole dish.

Topping:

Spread topping mixture on top of potatoes and bake at 350°F for 20 to 30 minutes.
