Preheat oven to 375 degrees F. Spray a 9x13 oven-safe baking dish with non-stick spray.
In a large bowl, combine sweet potatoes, sugars, salt, butter, vanilla, and eggs with a whisk or hand mixer until the sweet potato mixture is creamy and fluffy, about 3-5 minutes.
Pour sweet potato mixture into prepared baking dish.
Mix crust ingredients together in a medium sized bowl, then sprinkle generously and evenly over sweet potatoes in the baking dish.
Bake in oven for 50-55 minutes. Let cool for at least 30 minutes before serving, the crust should be brown and crunchy.
