Prep Time:
15 minutes
Chill Time:
1–2 hours
Total Time:
1 hour 15 minutes
Servings:
4–6
Ingredients
- 8 oz cream cheese, softened
- 1 cup heavy whipping cream, cold
- ½ cup plain Greek yogurt or sour cream
- 3–4 tablespoons powdered keto sweetener (such as Swerve Confectioners or monk fruit powdered)
- 2 tablespoons fresh lime juice
- 1 teaspoon lime zest
- 1 teaspoon vanilla extract
- A few drops green food coloring (optional)
- Crushed low-carb cookies or chopped nuts for topping (optional)
- Lime slices and extra zest for garnish
Instructions
- Beat the cream cheese. In a large bowl, beat the softened cream cheese with a hand mixer until completely smooth and creamy.
- Add the tangy base. Mix in the yogurt (or sour cream), powdered sweetener, lime juice, lime zest, and vanilla. Beat until uniform. Add a tiny drop of green food coloring if desired and blend.
- Whip the cream. In a separate bowl, whip the cold heavy cream until stiff peaks form.
- Fold gently. Stir one-third of the whipped cream into the cheesecake mixture to lighten it. Gently fold in the remaining whipped cream until no white streaks remain, taking care not to deflate.
- Spoon and top. Divide the fluff into serving glasses or a dish. If using a crunchy topping, layer it on the bottom or sprinkle on top now.
- Chill. Cover and refrigerate for at least 1–2 hours (overnight is best). Garnish with lime slices and extra zest before serving.
Notes
- For the smoothest texture, always use powdered sweetener; granulated will leave a gritty feel.
- Add more lime zest rather than extra juice for a stronger lime punch without thinning the fluff.
- For a crunchy topping, crush a few keto vanilla wafers, toast chopped pecans, or make a quick almond flour crumble.
- Store covered in the fridge for up to 4 days. Freeze for a scoopable frozen dessert.
