Ingredients
- 8 ounces cream cheese, at room temperature, softened
- 1 cup heavy cream, cold
- 2/3 cup 5 Minute Lemon Curd ((sugar-free if keto))
- 1/3 cup Swerve confectioners
Instructions
Step 1: Whip the Cream
Pour the cold heavy cream into a large mixing bowl. Using a hand or stand mixer, whip the cream on medium-high speed until soft peaks form. Be careful not to over-whipโthe cream should be light, airy, and hold gentle peaks when the whisk is lifted. Set aside.
Step 2: Prepare the Cream Cheese Base
In a separate bowl, add the softened cream cheese. Using a hand mixer, beat the cream cheese until smooth and creamy. This will prevent any lumps in your final fluff.
Step 3: Add Lemon and Sweetener
Add the lemon curd and Swerve confectioners to the whipped cream cheese. Continue mixing until the ingredients are fully incorporated. Taste and adjust sweetness if needed.
Step 4: Fold in the Whipped Cream
Gently fold the whipped cream into the cream cheese mixture using a spatula. Use a light, circular motion to maintain the fluffy texture. Stop once the mixture is uniform and smooth.
Step 5: Chill Before Serving
Transfer the fluff to serving glasses or a bowl. Chill in the fridge for at least 10 minutes, or in the freezer for a quicker chill. This helps the flavors meld together and the texture set.
Step 6: Serve and Enjoy
Once chilled, serve your keto lemon cheesecake fluff as is, or top with fresh berries, zest, or a sprinkle of Swerve for extra flair.
๐ก Tips for the Best Fluff:
- Make sure the heavy cream is very cold before whippingโit whips better and holds its shape longer.
- Softened cream cheese is key; room temperature works best.
- Gently folding preserves the airy texture, so avoid overmixing.
- You can prepare this a few hours in advance; it keeps well in the fridge for up to 3 days.
