In a large mixing bowl, beat the softened cream cheese using a hand mixer or stand mixer until it becomes smooth and fluffy, creating a creamy base for the fluff.

Add the Greek yogurt, sugar-free cheesecake pudding mix, almond milk, protein powder, sweetener (if using), and vanilla extract to the bowl. Beat the mixture on medium speed for 2 to 3 minutes until it is light, smooth, and creamy.

Allow the mixture to sit undisturbed for 5 minutes so the pudding mix can thicken, enhancing the texture of the fluff.

Spoon the cheesecake fluff into individual bowls or cups, then chill them in the refrigerator for at least 30 minutes. Chilling improves the texture and firmness, making it easier to enjoy.

Serve the fluff plain or topped with your choice of light whipped topping, fresh berries, or a sprinkle of crushed graham crackers for added flavor and crunch.
