Step 1

Preheat the oven to 350° and wrap sweet potatoes in aluminum foil. Bake until tender, approximately 1 hour. Butter a 3 quart baking dish. Set aside.

Step 2

Remove potatoes from the oven and once cool enough to handle, unwrap and scoop out the flesh and place in a large bowl.

Step 3

Add sugar, butter, vanilla extract and eggs to the bowl and use a potato masher or electric mixer to mash thoroughly. Spoon mixture into prepared baking dish.

Step 4

In a medium bowl, stir all the crust topping ingredients together and spread evenly over the sweet potato mixture.

Step 5

Bake uncovered for 30 minutes and let sit for 20 minutes before serving.
