Maple Sweet Potato Casserole

Preheat the oven to 350 degrees.

Poke some holes in the sweet potatoes with a fork, then put into the preheated oven, and bake till tender (approximately 40-60 minutes depending on the size of the potato). Remove potatoes from oven and cool. After the potatoes have cooled enough to handle, peel the skins and put the potatoes through a ricer to mash. Add the remaining ingredients (except marshmallows) to the potatoes and mix to blend ingredients. Spoon the potato mixture into a buttered oven safe dish and bake for 20 minutes. Take dish out of oven and top potatoes with marshmallows. Then return to oven and bake for about 8 minutes or till marshmallows are puffy and golden brown.
