It’s often flavored with vanilla or lemon zest and can be topped with low-carb berries or nuts for extra texture.

Key Ingredients Explained
- Cream Cheese: The base of the fluff, providing the tangy, rich flavor that mimics cheesecake.
- Heavy Whipping Cream: Adds volume and creaminess when whipped, creating the light texture.
- Keto Sweetener: Erythritol or monk fruit sweeteners keep it sugar-free without bitterness.
- Vanilla Extract: Enhances flavor with a warm, sweet aroma.
- Optional Lemon Zest or Juice: Adds a bright, refreshing tang that complements the creaminess.
How to Make Keto Cheesecake Fluff
Ingredients:
- 8 oz (225g) cream cheese, softened
- 1 cup (240ml) heavy whipping cream, cold
- 1/3 cup powdered erythritol or preferred keto sweetener
- 1 teaspoon vanilla extract
- Optional: 1 teaspoon lemon zest or 1 tablespoon lemon juice for a citrusy twist
Instructions:
- Beat the Cream Cheese: In a large mixing bowl, use a hand mixer to beat the softened cream cheese until smooth and creamy, about 2-3 minutes.
- Add Sweetener and Flavor: Add the powdered erythritol and vanilla extract (and lemon zest or juice if using). Beat again until fully combined and smooth.
- Whip the Heavy Cream: In a separate chilled bowl, whip the cold heavy cream until stiff peaks form. This usually takes about 3-4 minutes with an electric mixer.
- Fold Together: Gently fold the whipped cream into the cream cheese mixture using a spatula. Fold carefully to keep the airiness intact, creating a light, fluffy texture.
- Chill and Serve: Transfer the fluff into serving bowls or jars and chill in the refrigerator for at least 30 minutes to let the flavors meld and texture firm up.
Serving Suggestions
- Top with fresh keto-friendly berries like raspberries, blackberries, or strawberries.
- Sprinkle with chopped nuts such as pecans or walnuts for crunch.
- Layer with keto-friendly chocolate shavings or cocoa powder for a mocha twist.
- Use as a filling for low-carb crepes or fat bombs.
