Prepare the Cream Cheese Mixture:
In a large mixing bowl, beat the softened cream cheese, powdered sugar, and vanilla extract together until smooth and creamy.
Add the Cherry Pie Filling:
Gently fold in the cherry pie filling, making sure it’s evenly incorporated.
Fold in the Whipped Topping:
Add the whipped topping to the bowl and gently fold it into the mixture. Be careful not to overmix to maintain the fluffiness.
Add the Marshmallows:
Stir in the mini marshmallows for added texture and sweetness.
Chill:
Cover the bowl and refrigerate for at least 1 hour to allow the flavors to meld together.
Serve:
Spoon the cherry cheesecake fluff into serving bowls or glasses. Garnish with graham cracker crumbs for a cheesecake-inspired crunch, if desired.
