In a small bowl, whisk the milk and pudding mix for 2 minutes. Let stand for 2 minutes or until soft-set.
In a large bowl, beat the yogurt, cream cheese, sour cream and vanilla until smooth. Fold in pudding mixture and 1 cup whipped topping.
Place a third of the cake cubes in a 4-qt. trifle bowl. Top with a third of the pudding mixture, a third of the berries and half of the remaining whipped topping. Repeat layers once. Top with remaining cake, pudding and berries. Serve immediately or refrigerate.
