Caramel Apple Dessert

My kids all love apples and this fun dessert had them all cheering! You don't even have to tell anyone that this recipe is lower in fat and calories. Recipe from Kraft...

45 Reduced Fat Nilla Wafers, finely crushed (about 1-1/2 cups)
1/4 cup soft margarine, melted (I used butter)
1 pkg. (8 oz.) Fat-Free Cream Cheese, softened
1 Tbsp. Splenda No Calorie Sweetener, Granulated
3-1/4 cups cold fat-free milk, divided
1 tub (8 oz.) Cool Whip Sugar Free Whipped Topping, thawed, divided
2 pkg. (1 oz. each) Jell-o Vanilla Flavor Fat-Free Sugar-Free Instant Pudding
1/2 cup sugar-free caramel ice cream topping, divided
1 each red and green apple, chopped
1/4 cup peanuts, chopped (I omitted)

MIX wafer crumbs and margarine; press onto bottom of 13x9-inch pan. Beat cream cheese, Splenda and 1/4 cup milk with mixer until well blended. Stir in 1 cup Cool Whip; spread over crust.

BEAT pudding mixes and remaining milk with whisk 2 min. Stir in 1/4 cup caramel topping. Spoon over cream cheese layer; top with remaining Cool Whip.

REFRIGERATE 8 hours or until firm. Top with apples, nuts (if desired) and remaining caramel topping just before serving. Makes 16 servings.

***Alli's substitutions: The only thing I substituted was the butter for margarine and regular caramel for sugar-free caramel topping because I couldn't find sugar-free. The next day, I found sugar-free caramel at Target! Here are some suggestions, if needed: 

• Substitute graham crackers Nilla Wafers (in equal amounts)
• butter for margarine
• 1 1/2 small packets sugar sweetener -or- 1 Tbs. white sugar for the Splenda granulated
• regular caramel ice cream topping for the sugar-free caramel topping
