Instructions

  1. Step 1: Preheat the oven to 350°F. Boil 3 pounds peeled and cubed sweet potatoes in a large pot of water until tender, about 15 minutes, then drain and mash until smooth.
  2. Step 2: In a mixing bowl, combine the mashed sweet potatoes with 1/2 cup unsalted butter (softened), 1/2 cup brown sugar, 2 teaspoons ground cinnamon, 1 teaspoon vanilla extract, 2 large eggs, and 1/4 cup milk. Mix until well blended and creamy.
  3. Step 3: Transfer the sweet potato mixture to a greased 9x13-inch baking dish and smooth the top.
  4. Step 4: In a separate bowl, mix 1 cup chopped pecans, 1/2 cup all-purpose flour, 1/2 cup granulated sugar, 1/2 teaspoon ground cinnamon, and 1/4 teaspoon salt. Cut in 1/4 cup cold unsalted butter until crumbly.
  5. Step 5: Sprinkle the pecan crumble evenly over the sweet potato layer and bake uncovered for 35-40 minutes until the topping is golden brown and crisp.
