Volcano Potatoes

3 cups mashed potatoes
1/2 cup milk
1/2 cup whipping cream, beaten until stiff peaks form
1/2 cup shredded cheese

Preheat oven to 350 degrees F. Butter an 8-inch round baking dish.

Mix together mashed potatoes and milk to make fluffy. Pile into prepared baking dish, mounding to shape like a volcano, with a crater in center top. Fold together whipped cream and shredded cheese. Pour mixture over potatoes. Bake at 350 degrees F for about 20 minutes or until lightly browned.
