Spread the sweet potato mixture evenly into a greased baking dish. Using a spatula, aim for a uniform layer, which allows it to bake consistently and achieve that delightful texture.
Combine brown sugar, all-purpose flour, softened butter, and chopped pecans in a separate bowl to create the topping. Mix until crumbly, and feel free to adjust the pecans to your liking for extra crunch.
Sprinkle the pecan topping evenly over the sweet potato base. This will create a lovely contrast in texture when baked, with the topping becoming beautifully golden and crisp.
