Initial Mixture Preparation: In a substantial mixing bowl, begin by combining the cream cheese, cheesecake pudding mix, vanilla extract, and whole milk. Utilize an electric mixer or a hand whisk to blend these ingredients until they achieve a uniform consistency. This initial step is critical as it forms the creamy base of the dessert.
Incorporation of Whipped Topping: Carefully fold the frozen whipped topping into the cream cheese mixture using a spatula. Execute this step with gentle motions to ensure the mixture remains light and airy, which is pivotal for achieving the desired fluff texture.
Addition of Flavor Components: Proceed to gently fold in the mini marshmallows and cherry pie filling into the creamy base. Ensure an even distribution of the marshmallows and cherries throughout the mixture, maintaining a delicate hand to preserve the fluff’s airy quality.
Refrigeration: Transfer the completed mixture to a suitable serving dish and refrigerate. This cooling period allows the flavors to meld and the dessert to achieve a slightly firmer consistency, enhancing both its taste and ease of serving. The dessert should be chilled until it is ready to be served, ideally for at least one hour.
