Ingredients
| Ingredient | Quantity |
|---|---|
| Full-fat cream cheese, softened | 226 g (8 oz) |
| Heavy whipping cream, cold | 240 ml (1 cup) |
| Powdered keto sweetener (erythritol/allulose) | 80 ml (½ cup) |
| Vanilla extract | 1 teaspoon |
| Lemon juice | 1 tablespoon |
| Fresh berries (optional, for serving) | 60–100 g (½–1 cup) |
Instructions
Step 1
In a large mixing bowl, beat the softened cream cheese with the keto sweetener, vanilla extract, and lemon juice until smooth and creamy. Use an electric mixer for best results so there are no lumps — the mixture should become light and velvety as you whip it.
Step 2
In a separate chilled bowl, whip the heavy cream until stiff peaks form. This aerates the cream and gives your cheesecake fluff its signature light, airy texture. Make sure the cream is cold and whip until it holds shape firmly.
Step 3
Gently fold about half of the whipped cream into the cream cheese base using a rubber spatula. This initial fold lightens the mixture and makes it easier to combine the rest without deflating the air you just whipped in.
Step 4
Carefully fold in the remaining whipped cream until fully incorporated and no white streaks remain. Once combined, spoon or pipe the fluff into individual serving bowls and chill for at least 30 minutes to set and develop flavor. Serve topped with fresh berries if desired.

How to Serve
FAQs
What makes this dessert keto-friendly?
Keto Cheesecake Fluff uses low-carb sweeteners and high-fat dairy, keeping carbs minimal while delivering rich flavor.
Can I use another sweetener instead of erythritol?
Yes, allulose or powdered monk fruit works well — just ensure it’s powdered to keep texture smooth.
Do I have to chill it before eating?
Chilling enhances texture and flavor, so it’s best, though you can enjoy it immediately if you’re in a rush.
How long will leftovers keep?
Stored in an airtight container, the fluff stays fresh in the fridge for up to 5 days.
Can I make this ahead of time?
Absolutely — make the fluff a day ahead and garnish right before serving for best presentation.
Why is my fluff not airy?
It may be due to under-whipped cream or over-mixing after folding — ensure stiff peaks and gentle folding.
Can I freeze Keto Cheesecake Fluff?
Freezing isn’t recommended as it can affect texture; refrigerate instead for best results.
