For the caramel:
1 cup sugar
1 cube (1/2 cup) butter
1 cup corn syrup
1 can sweetened condensed milk
1 tsp vanilla
Combine all ingredients in a large glass bowl and microwave for 3 minutes. Stir. Continue this cycle (microwave for 2-3 minutes, then stop and stir) four to five times, until caramel turns a nice golden color. Stir in the vanilla.
Form mini apples by using a melon baller. Pat the cut apple dry with a paper towel. Use wooden shish Kebob skewers, cut in half, to skewer the apples. Dip in the warm caramel leaving part of the apple skin exposed. Optional: roll caramel in toppings, like sprinkles, nuts, or colored sugar.
Hint: it definitely is advisable to the put the dipped apples in small paper baking cupcake liners. (Keeps things neat)
