4 Medium size sweet potatoes (about 4 cups mashed)
1/2 cup butter or margarine
2 teaspoons salt
1/2 cup orange juice
1/2 teaspoon cinnamon
1/2 - 1 bag mini marshmallows (you can use large marshmallows, but mini marshmallows work better)
Preheat the oven to 400 degrees Fahrenheit.
Discard the ends of the sweet potatoes. Wrap the rest of the sweet potatoes in aluminum foil. Place the sweet potatoes on a baking sheet and place the baking sheet in the oven. Bake for 60 to 70 minutes or until the sweet potatoes are soft to the touch. Then change the temperature down to 350 degrees Fahrenheit.
Peel the sweet potatoes and place them in a medium size casserole dish. Use a fork or spoon to mash the sweet potatoes. Then mix in the butter, salt, orange juice and cinnamon. Top with enough marshmallows to cover the sweet potatoes.
Bake the sweet potatoes in the oven for 10 minutes. Cool for 5 to 10 minutes and serve.
