Cut the angel food cake into cubes and set aside.
In a mixing bowl, whisk together the instant vanilla pudding mix, milk, and sour cream or plain Greek yogurt until smooth. If desired, add almond extract for an extra layer of flavor.
In a trifle bowl or a large glass dish, create a layer using half of the angel food cake cubes.
Spoon half of the cherry pie filling over the cake cubes, spreading it evenly.
Pour and spread half of the prepared vanilla pudding over the cherry layer.
Repeat the layers using the remaining angel food cake cubes, cherry pie filling, and vanilla pudding.
Top the trifle with whipped topping, creating a fluffy and smooth layer.
If desired, garnish with toasted sliced almonds for an added crunch.
Refrigerate the trifle for at least 4 hours, allowing the flavors to meld together.
Once chilled, serve and watch it disappear in no time!
