Strawberry Heaven on Earth Cake

In a large mixing bowl, whisk together the instant vanilla pudding mix and cold milk for about 2 minutes, or until the pudding has thickened.
Stir in the sour cream until the mixture is smooth and well combined.
Assemble the Cake:

In a large trifle dish or 9×13-inch baking dish, layer the cubed angel food cake on the bottom.
Spoon half of the vanilla pudding mixture over the cake cubes and spread it evenly.
Add the Strawberry Layers:

Layer half of the fresh sliced strawberries over the pudding mixture.
Spoon half of the strawberry pie filling over the fresh strawberries.
Repeat the Layers:

Add another layer of angel food cake cubes on top of the pie filling.
Spread the remaining pudding mixture over the second layer of cake cubes.
Add the remaining fresh strawberries and top with the rest of the strawberry pie filling.
Top with Whipped Topping:

Spread the whipped topping (Cool Whip) evenly over the top layer.
Garnish with additional fresh strawberries or a drizzle of strawberry sauce, if desired.
Chill and Serve:

Refrigerate the cake for at least 4 hours, or preferably overnight, to allow the flavors to meld together and the cake to absorb the creamy filling.
