Ingredients For the Fluff

8 ounces cream cheese, softened
1 cup heavy whipping cream
¼ cup powdered low-carb sweetener (such as erythritol or allulose)
2 tablespoons fresh Key lime juice
1 teaspoon finely grated Key lime zest
1 teaspoon vanilla extract

Optional Garnish

Sugar-free whipped cream
Extra lime zest
Thin lime slices
Fresh mint leaves

Step-by-Step Instructions

Step 1: Soften the Cream Cheese

Allow the cream cheese to sit at room temperature for about 30 minutes until soft and easy to mix.

Step 2: Whip the Cream

In a chilled mixing bowl, beat the heavy whipping cream until soft peaks form. Set aside.

Step 3: Prepare the Cream Cheese Mixture

In another large bowl, beat the softened cream cheese until completely smooth and creamy. Add the powdered sweetener, lime juice, lime zest, and vanilla extract. Beat until fully combined.

Step 4: Fold in the Whipped Cream

Using a spatula, gently fold the whipped cream into the cream cheese mixture in batches. Mix carefully until the mixture becomes light, fluffy, and smooth without deflating the whipped cream.

Step 5: Taste and Adjust

Taste the mixture and add a little more lime juice for extra tang or a touch more sweetener if you’d like it sweeter.

Step 6: Fill the Dessert Cups

Divide the fluffy mixture evenly among 4–6 small dessert cups or serving glasses. Smooth the tops with the back of a spoon.

Step 7: Chill

Cover and refrigerate the dessert cups for at least 2 hours to allow the flavors to blend and the texture to firm up.

Step 8: Garnish

Before serving, top each cup with a swirl of sugar-free whipped cream, fresh lime zest, a thin lime slice, or a small mint leaf for an elegant finish.

Step 9: Serve

Serve the dessert well chilled for the creamiest texture and brightest citrus flavor.

Tips, Notes & Q&A

Tips

Fresh Key lime juice provides the best flavor, but regular fresh lime juice also works well.
Chill the mixing bowl before whipping the cream for quicker, fluffier results.
Fold gently to keep the mixture light and airy.
Store covered in the refrigerator for up to 4 days.
For a firmer mousse-like texture, chill overnight before serving.
Q: Is this completely zero carb?
Not exactly. Ingredients like cream cheese and fresh lime juice naturally contain a small amount of carbohydrates, so the dessert is better described as very low-carb rather than truly zero carb.

Q: Can I use bottled lime juice?
Fresh lime juice is recommended for the brightest flavor, but bottled lime juice can be used if needed.

Q: Can I freeze these dessert cups?
Yes. Freeze for up to 1 month. Thaw in the refrigerator for about 30 minutes before serving for the best texture.
