Dip and swirl apples in melted caramel mixture, using a spoon to spread evenly.
Place on waxed paper until caramel sets or refrigerate 15 minutes for quicker results.
Indulgent caramel nut apples: Place chopped, salted skinless peanuts or toasted walnuts on waxed paper. Press bottom of caramel-dipped apple into nuts. Drizzle melted milk or semi-sweet chocolate over apples.
