In a large mixing bowl, combine the cherry pie filling and drained pineapple chunks.
Gently fold in the sweetened condensed milk until well combined.
Add the chopped walnuts to the mixture, ensuring they are evenly distributed.
Carefully fold in the mini marshmallows until they are evenly distributed throughout the mixture.
Finally, gently fold in the thawed Cool Whip until all ingredients are well combined, and the mixture has a smooth and creamy consistency.
Transfer the Cherry Delight mixture into a large serving dish or individual dessert bowls.
Cover the dish with plastic wrap and refrigerate for at least 2 hours, allowing the flavors to meld and the dessert to chill.
Once chilled, serve the Heavenly Cherry Delight straight from the refrigerator and enjoy the luscious combination of cherries, pineapple, walnuts, marshmallows, and the creamy sweetness of condensed milk and Cool Whip.
This delightful and easy-to-make dessert is perfect for a couple to enjoy throughout the week. The combination of textures and flavors will make every bite a heavenly experience.
