4cupsof sweet potatoescooked and mashed (JC's note: I prefer to use Bruce's canned yams)
1 1/3stick of butterunsalted, melted
Preheat oven to 375F.
Combine sweet potatoes (yams), sugar, beaten eggs, salt, vanilla extract, and melted butter; beat until well-incorporated, roughly 2-3 minutes.
Combine brown sugar, pecans, flour, butter, and vanilla extract until uniformly mixed. In a buttered baking dish, pour in sweet potato mixture and spread the topping evenly across the potatoes. Bake for 30 minutes, or until the sweet potatoes are hot and the topping is browned.
