Prepare the Pudding: In a large bowl, whisk together the instant vanilla pudding mix and milk until thickened, about 2 minutes. Let it sit for a few minutes to fully set.

1. Mix in the Whipped Topping: Gently fold the whipped topping into the pudding mixture until smooth and well combined.
2. Assemble the Dessert: In a 9×13-inch baking dish, layer the graham crackers at the bottom of the dish to form a solid base.
3. Add the Pudding Layer: Spread half of the pudding mixture over the graham crackers, smoothing it out into an even layer.
4. Add Another Layer of Graham Crackers: Place another layer of graham crackers on top of the pudding layer.
5. Top with Remaining Pudding: Spread the remaining pudding mixture evenly over the second layer of graham crackers.
6. Add the Cherry Topping: Spread the cherry pie filling evenly over the top of the pudding layer.
7. Chill the Dessert: Cover with plastic wrap and refrigerate for at least 4 hours, or overnight for best results.
8. Serve and Enjoy: Once chilled, slice and serve. Enjoy the creamy, fruity layers of this easy no-bake treat!
