Prepare vanilla pudding according to package directions using 2 cups of milk.

Gently fold 4 ounces of Cool Whip into the prepared pudding.

Refrigerate the pudding mixture.

In a separate bowl, mix cream cheese, powdered sugar, and sour cream until smooth.

Refrigerate the cream cheese mixture.

Cut the pound cake into bite-sized pieces.

In a large glass bowl, create layers with the cake pieces, pudding mixture, fresh fruit (strawberries, blueberries, raspberries), and cream cheese mixture.

Repeat layers as needed, depending on the size of the bowl.

Chill the assembled trifle for at least 3 hours before serving.
