Jason's Mashed Sweet Potatoes with Pecan Streusel Topping

We are having a little homecoming party for my parents this weekend and making roast turkey and some other "fall" dishes.  This is one of Jason's specialties that he has agreed to make for the occasion! 

Ingredients

• 4 1/2 cups cooked and mashed sweet potatoes
• 1/2 cup butter, melted
• 1/3 cup milk
• 1 cup white sugar
• 1/2 teaspoon vanilla extract
• 2 eggs, beaten
• 1 cup light brown sugar
• 1/2 cup all-purpose flour
• 1/3 cup butter
• 1 cup chopped pecans

Directions

1. Preheat oven to 350 degrees F (175 degrees C). Grease a 9x13 inch baking dish.
2. In a large bowl, mix together mashed sweet potatoes, 1/2 cup butter, milk, sugar, vanilla extract, and eggs. Spread sweet potato mixture into the prepared baking dish. In a small bowl, mix together brown sugar and flour. Cut in 1/3 cup butter until mixture is crumbly, then stir in pecans. Sprinkle pecan mixture over the sweet potatoes.
3. Bake for 25 minutes in the preheated oven, or until golden brown.
