Preheat oven to 375°F. Bake sweet potatoes on a foil-lined baking sheet for 1 hr or until tender. Let stand until cool enough to handle.

Peel sweet potatoes and mash into large bowl. Stir in 1 tablespoon of butter, milk, eggs, vanilla, 1 teaspoon cinnamon and salt. Spoon into a lightly greased 11x7 baking dish.

In a medium glass bowl, stir in one tablespoon butter, honey, oats, pecans and remaining teaspoon of cinnamon. Sprinkle over casserole. Bake for 30 minutes, until golden brown and heated through.
