- cooking spray, for the baking dish
- 6 medium-sized sweet potatoes, peeled
- 1/2 cup butter, melted
- 1/2 cup sugar
- 1/3 cup milk
- 2 large eggs
- 1 teaspoon vanilla extract
- 1/2 cup firmly packed light brown sugar
- 1/2 cup finely chopped pecans
- 2 tablespoon all-purpose flour
- 2 tablespoon butter, softened
- Preheat the oven to 350 degrees and lightly grease an 11-by-7-inch baking dish with cooking spray.
- Put the sweet potatoes in a pot just large enough to fit and fill with water just to cover. Bring to a boil, and cook until tender, for 30-35 minutes. When cool enough to handle, peel the sweet potatoes, place in a bowl, and mash.
- Combine the mashed sweet potatoes, melted butter, and next 4 ingredients. Beat at medium speed with an electric mixer until smooth. Spoon into the baking dish.
- In a bowl, combine the brown sugar and remaining ingredients. Sprinkle over the sweet potato mixture. Bake for 30 minutes.
