Pour the sweet potato mixture into the prepared baking dish.

In another bowl, add the pecans, the cinnamon, the remaining 4 tablespoons of butter, and the remaining brown sugar and stir to combine.

Step 10

Sprinkle the pecan mixture over the center of the sweet potato mixture.

Step 11

Bake the sweet potato mixture until it is bubbly and warmed through, about 30-35 minutes.
