Begin by placing the apple pie filling in a bowl. Use scissors to cut the apple pieces into smaller chunks. Then, sprinkle the cinnamon and nutmeg into the filling and set it aside.
In a separate large bowl, combine the instant vanilla pudding mix, cold milk, and powdered sugar. Mix them well until everything is blended together.
Now, add the heavy cream and vanilla extract to the pudding mixture. With a hand mixer, beat this mixture until it becomes creamy and thick, which should take about 3 to 4 minutes.
Next, grab a 9×13-inch baking dish and lay down a single layer of cinnamon graham crackers.
Spoon half of the apple pie filling over the graham crackers, then pour in half of the vanilla pudding mixture.
Repeat the layers: add another layer of graham crackers, the remaining apple pie filling, and finish with the rest of the pudding.
Top it all with one final layer of graham crackers.
To get that delightful caramel drizzle, heat the caramel topping in the microwave until it’s warm and pourable.
Pour the warm caramel over the top layer of graham crackers, making sure to spread it out evenly.
Finally, refrigerate your masterpiece for at least 4 to 6 hours, or ideally overnight, allowing those beautiful flavors to meld together and set.
Before serving, drizzle on some additional caramel sauce if you’d like to go the extra mile.
