Sweet Potato Puffs

1 1/2 pounds sweet potatoes, cooked and mashed

2 tablespoons margarine, melted

1/3 cup firmly packed brown sugar

1/2 teaspoon cinnamon

1 teaspoon vanilla

8 large marshmallows (I used 5 or 6 little ones squished together to equal one large)

2 cups cornflakes, crushed

Preheat about 4 inches of oil in pan on medium to medium high.  Combine sweet potatoes, margarine, brown sugar, cinnamon, and vanilla; chill.  Form balls around marshmallows with potato mixture and roll in cornflakes.  Fry in skillet about 15 to 30 seconds or until brown.
