Prepare the Angel Food Cake: Preheat your oven and prepare the angel food cake according to the package instructions. Allow it to cool completely before slicing.
Mix the Cheesecake Filling: In a medium bowl, whisk together the instant cheesecake pudding mix and milk until the mixture thickens, which should take a couple of minutes.
Layer the Cake: Once the cake is cool, slice it into layers. Take a serving dish and begin layering the cake slices with the cheesecake mixture. Alternate between cake and filling layers, finishing with the cheesecake on top.
Chill: Cover the dish with plastic wrap and refrigerate for at least 2 hours, allowing the flavors to meld together beautifully.
Serve and Enjoy: Once chilled, slice and serve. Enjoy your slice of heaven!
