Follow these simple steps to create your own Marshmallow Whip Cheesecake Heaven:

1. Prepare Your Mixing Bowls: Gather all your ingredients and a large mixing bowl for the filling. Make sure the cream cheese is softened for easy blending.
2. Beat the Cream Cheese: Using an electric mixer, beat the softened cream cheese in the large mixing bowl until smooth and creamy.
3. Add Sugar and Vanilla: Gradually mix in the powdered sugar and vanilla extract. Continue mixing until the mixture is smooth and creamy.
4. Incorporate the Marshmallow Fluff: Carefully fold in the marshmallow fluff until well combined. This will add fantastic sweetness and fluffiness to your cheesecake filling.
5. Whip the Cream: In a separate bowl, whip the heavy cream until soft peaks form. Be careful not to over-whip, as you want it to remain light and airy.
6. Combine Mixtures: Gently fold the whipped cream into the marshmallow cream cheese mixture. Use a spatula for the best results, being cautious not to deflate the whipped cream.
7. Sour Cream Addition: Finally, fold in the sour cream, which adds a nice tang to balance the sweetness.
8. Fill the Crust: Pour the cheesecake mixture into the pre-made graham cracker crust, smoothing the top with a spatula.
9. Chill: Cover the cheesecake with plastic wrap and refrigerate for 4-6 hours or overnight. This will allow it to set properly.
10. Serve: Once chilled, slice and serve topped with your choice of additional toppings for an extra touch of flavor.

With these straightforward instructions, you’ll create an amazing cheesecake that’s beautifully light and luscious. Enjoy the baking process; it’s an adventure all on its own!
