It's not Thanksgiving without my rummy sweet potatoes! I've been making them for years. They are not health food but once a year won't killya.

RUMMY SWEET POTATOES
Peel 3 or 4 large sweet potatoes and cut them into chunks. Boil until they're soft enough to cut with a fork. Drain them, put them in a large bowl, and mash. Alternately, you can bake them. I like to use the hand mixer to mash them because it only takes a minute to get them completely smooth. Meanwhile preheat the oven to 350 F (175 C).
Mix in the following (one at a time):
1/2 cup sugar
2 eggs, beaten
1/3 cup milk
1 Tbsp vanilla
1/2 cup melted butter
1/3 cup dark rum (for a variation I like to use Captain Morgan spiced rum)
Pour into 9x9 baking dish.
In another bowl, mix the streusel topping:
2 cups brown sugar
2/3 cup flour
2/3 cup melted butter
1 cup finely chopped pecans or hazelnuts (optional, it's fine without nuts)
Carefully spread the topping over the sweet potato mixture, covering as much of it as possible. Bake uncovered 30-45 minutes or until streusel topping is lightly browned. Let stand at least 20 minutes before serving; it can stand for hours if necessary, and is actually better that way. It's perfectly good at room temperature so it's great for bringing to parties.
