Hi Nancy :-) I think that this must be the recipe that you are looking for.

Heath Bar Pie

1 graham cracker pie crust
1/3 cup caramel ice cream topping
1 1/2 cups milk
1 (4 serving size) box vanilla instant pudding
1 (8 ounce) container whipped topping
6 Heath candy bars (1 to 1 1/2 ounce each), chopped

Spread caramel topping into pie crust.

Beat milk and pudding mix for 2 minutes, let stand for 5 minutes.

Stir in whipped topping and chopped candy bars. Spoon into crust. Freeze for 4 hours or til set.

Before serving, let stand for 15 minutes so that pie can easily be cut. Store any leftovers in refrigerator.
Makes 1 (9 inch) pie
