Prepare Big Green Egg or other smoker for indirect cooking at 400⁰.
Place Sweet Potatoes on Big Green Egg and cook for 1:30 hours or until soft. Skewer should go into the potato with no resistance. Remove the sweet potatoes from the smoker and adjust vents so temperature drops to 350⁰.
Peel sweet potatoes and place in a large bowl. Add remaining ingredients and stir to combine. Spoon into cast iron skillet.
In a separate bowl add the pecans, brown sugar, flour, and melted butter. Stir to combine and sprinkle over potato mixture.
Place iron skillet on smoker and cook for 1 hour or until topping browns. Remove from smoker and serve.
