Apple Snickers Salad

My mother made this once after trying it at a potluck. I re-discovered it at a local deli. It's super easy and the right combination of healthy and sinful.
This is how I made it - feel free to add more or less of any ingredient.

4 granny smith apples, chopped
1 11.29 bag of fun size snickers (remove from wrappers and cut into thirds).
8 oz mini marshmallows
16 oz cool whip
1 1/2 cups chopped walnuts
butterscotch or caramel ice cream syrup

In a large bowl, combine apples, snicker, marshmallows and walnuts. Mix in cool whip. Drizzle syrup over the top (I used about 1/2 of a standard smuckers jar).

You can chill ahead of time but becareful because the cool whip can get gooey if not properly covered.
