Very Berry Pie

This recipe comes from Sunny. When I asked her if she had a favorite dessert recipe, her reply was, "Hmmm...no...YES! Very Berry Pie! It's almost homemade!" She also said, "You can substitute any berries you like. I like blackberries and raspberries. It's not really mine, since I got it from someone else, but I love it...so there!" It looks like a fast, yummy recipe -- good for when you feel like pie but don't feel like firing up the oven. Plus, it's fruity-fresh for spring.

1-3/4 cups whipped topping, divided
1 graham cracker crust (store-bought or homemade)
1 cup fresh raspberries
1 cup fresh blueberries
1 tablespoon sugar
1 cup cold milk
1 package instant white chocolate pudding mix (I'd try it with vanilla - MB)

Directions:
Spread 1/4 cup whipped topping into the crust.
Combine berries and sugar; spoon 1 cup over topping.
In a bowl, whisk the milk and pudding mix for 2 minutes; let stand for 2 minutes or until soft-set. Spoon over berries.
Spread with remaining whipped topping.
Top with remaining berries.
Refrigerate for 45 minutes or until set.
