In a medium bowl, combine the pudding mix and milk - whisk to combine well. Allow to set for about 5 minutes.
Add in the Cool Whip and fold to combine.
Lay out the trifle containers and use half of the Angel Food cake to create the first layer in the trifle containers.
Add a spoonful of the pudding mixture over the Angel Food cake.
Sprinkle with a few pieces of the strawberries, blueberries and raspberries.
Repeat another layer with the Angel Food cake, followed by the remaining pudding mixture.
Sprinkle each trifle with the remaining fruit pieces.
Allow the trifles to chill in the fridge for about 2 hours for the best results.
