Caramel Apple Salad

This is reeeeeeeally good. It came from my mother-in-law, but I have made it several times recently for various holiday parties and it is a huge hit. It is healthy too.... right??? Apples?? RIGHT?

Caramel Apple Salad
Serves: about 14?

1. In a large bowl, melt 1 stick of butter or margarine. Then whisk or beat in 1 cup confectioners sugar. Then stir in 1.5 cups (12 oz) cool whip.

2. Stir in all this yummy stuff:
+3ish granny smith apples (depending on size, skin on, cut up in small bite sized pieces)
+1 cup dry roasted peanuts
+2 king size snickers bars cut up in little pieces
+1 can of WELL DRAINED crushed pineapple

3. Keep chilled! This is not a make ahead recipe. You really only want to assemble it a couple hours max before serving because it can get a little watery. But I have prepped step two the day before and refrigerated. Then did step 1 and mixed it all together before the party.
