Place sweet potatoes in a Dutch oven (or a deep stockpot) and cover with water. Bring to a boil, then reduce heat to a simmer for 15 minutes or until potatoes are very tender. Drain water and let potatoes cool slightly (tip: place cooked sweet potatoes in the refrigerator to speed things up).
In a large bowl, add potatoes, 3/4 cup brown sugar, butter, egg, maple syrup, salt, and vanilla. Mash all ingredients together with a potato masher until mostly smooth.
Pour sweet potato mixutre into prepared baking dish and smooth into an even layer.
Sprinkle chopped pecans and remaining 1/4 cup bown sugar on top of potato mixture.
Bake casserole, uncovered, for 25 minutes.
Remove casserole from oven, then sprinkle mini marshmallows evenly across the top.
Return the casserole to the oven for another 5-10 minutes or until top of marshmallows begin to turn golden brown.
