Marshmallow Yam Casserole

PS, I doubled the recipe, saved the marshmallows for the end, and put an extra 1/4 cup of brown sugar.  Enjoy!

3 c. canned sweet potatoes, drained and mashed
1/4 c. brown sugar
1/2 tsp. salt
1 tsp. cinnamon
1 tsp. nutmeg
1 tbsp. butter, melted
1/4 c. cream
1 1/2 c. miniature marshmallows

Blend yams with sugar, salt, cinnamon, nutmeg, butter, cream and half the marshmallows with yams. Turn into a greased baking dish 9x13. Top with remaining marshmallows. Bake at 350 degrees for 20 minutes until mixture is puffy and marshmallows delicately browned. Serves 6-8.
