Step 1

Cook and peel sweet potatoes and mash with potato masher.

Step 2

Add butter and cream to potatoes just like if mashing regular potatoes. Stir in brown sugar, egg, vanilla, cinnamon and nutmeg. Spray a casserole dish with cooking spray.

Step 3

Put mashed sweet potatoes in dish and sprinkle nuts over the top. Bake in preheated 350 degree oven for 35 to 40 minutes.

Step 4

Remove from oven and add enough marshmallows to cover top of baking dish. Can use the miniature or big marshmallows. Put back in oven until marshmallows start to melt and brown on top. (I just stick mine under the broiler for a few minutes.)
