# Step-by-step guide:
01 - Preheat oven to 350°F. Lightly grease a 2-quart baking dish.
02 - Place sweet potatoes in a large pot, cover with water, bring to a boil, and simmer for 15 to 20 minutes until tender. Drain thoroughly.
03 - Mash sweet potatoes until smooth. Incorporate butter, milk, brown sugar, eggs, vanilla, cinnamon, nutmeg, and salt until creamy and well blended.
04 - Spoon the sweet potato mixture evenly into the prepared baking dish and smooth the surface.
05 - Evenly sprinkle mini marshmallows over the sweet potato layer if using marshmallow topping.
06 - Combine pecans, brown sugar, flour, and melted butter in a bowl until crumbly. Spread this mixture evenly over the sweet potatoes if opting for streusel.
07 - Bake uncovered for 25 to 30 minutes until the topping is golden and the filling is heated through.
08 - If using marshmallows, bake until they are puffed and golden brown, monitoring closely in the final minutes.
09 - Allow to cool for 5 to 10 minutes before serving to let flavors meld.
