Step-by-Step: Keto Cheesecake Fluff

Step 1: Prepare Your Ingredients
Start by taking your cream cheese out of the refrigerator to soften. This will make it easier to whip and incorporate into the fluff.
Step 2: Mix the Cream Cheese
In a mixing bowl, add the softened cream cheese. Use a hand mixer or stand mixer to beat it until it’s smooth and creamy, about 2 minutes.
Step 3: Add Sweetener, Lemon Juice, and Vanilla
To the cream cheese, add the powdered sweetener, lemon juice, and vanilla extract. Mix again until fully combined and smooth.
Step 4: Whip the Heavy Cream
In a separate bowl, pour in the double cream/heavy cream. Using a mixer, whip the cream until stiff peaks form. This will take about 3-5 minutes, so keep an eye on it to avoid over-whipping.
Step 5: Combine Cream Cheese and Whipped Cream
Gently fold the whipped cream into the cream cheese mixture using a spatula. Be careful not to deflate the whipped cream; you want to keep it light and fluffy.
Step 6: Add Lemon Zest
Fold in the lemon zest to the mixture, which will give your Keto Cheesecake Fluff a delightful citrus flavor.
Step 7: Serve and Add Berries (Optional)
Spoon the fluff into serving dishes or ramekins. If desired, top with fresh raspberries or other berries for a pop of color and added flavor.
Step 8: Chill and Enjoy
Refrigerate the Keto Cheesecake Fluff for at least 30 minutes to allow the flavors to meld and the texture to set. Serve chilled and enjoy every bite!

Flavor Logic
The combination of cream cheese and heavy cream is a classic base for cheesecake, providing the rich, creamy texture that fans of cheesecake adore. The Keto Cheesecake Fluff takes this beloved flavor and lightens it up, making it perfect for those watching their carbohydrate intake. The addition of lemon juice and zest introduces a zesty brightness that cuts through the richness, making every spoonful refreshing and satisfying. The sweetness from the powdered sweetener balances the tartness of the lemon, creating a harmonious flavor profile.
Storing Tips & Timelines
To keep your Keto Cheesecake Fluff fresh, store it in an airtight container in the refrigerator. It can last up to 3-4 days. However, for the best flavor and texture, it’s recommended to consume it within the first 2 days. If you decide to add fresh berries, wait until just before serving to add them, as they can release moisture and affect the fluff’s texture.
Quick Questions
Can I use regular sugar instead of powdered sweetener?
While you can use regular sugar, it will not keep the recipe keto-friendly. Powdered sweeteners are preferred for their low-carb content and to maintain the fluff’s texture.
Can I make this ahead of time?
Yes! This dessert can be made a day in advance. Just store it in the refrigerator until you’re ready to serve.
Is this dessert suitable for a keto diet?
Absolutely! With low-carb ingredients, this Keto Cheesecake Fluff is a perfect dessert option for those following a keto lifestyle.
Can I freeze Keto Cheesecake Fluff?
It’s best enjoyed fresh, but if you need to freeze it, place it in an airtight container. It can be frozen for up to a month, but the texture may change once thawed.
