Sweet, crunchy, and the ultimate Thanksgiving side dish, this Sweet Potato Casserole with Walnuts is a must make recipe!
In a medium bowl, add the topping ingredients. With a fork, mix all the ingredients together until a crumble forms. Set the bowl aside.
When the potatoes are cool enough to handle, peel the potatoes, and place them in a large mixing bowl.
Add the sugar, eggs, milk, butter, and vanilla to the bowl and mash all the ingredients together.
Crumble the brown sugar topping over the sweet potato mixture.
