Ingredients for Sugar-Free Cheesecake Mousse Fluff

Main Ingredients:

• 8 oz full-fat cream cheese, softened

• ½ cup heavy whipping cream (cold)

• ¼ cup powdered erythritol (or monk fruit/allulose)

• 1 tsp vanilla extract

• 1 tsp lemon juice

• Zest of ½ lemon (optional)

• Pinch of salt

Optional Add-Ins:

• 1–2 tbsp sugar-free peanut butter or almond butter

• 2 oz melted sugar-free dark or white chocolate

• ½ tsp matcha powder

• ¼ cup crushed berries or low-carb jam

Step-by-Step Instructions

Step 1: Soften Cream Cheese

Let cream cheese sit at room temperature for 30–60 minutes. This prevents lumps and gives your mousse a silky texture.

Step 2: Mix the Base

Beat cream cheese, sweetener, lemon juice, vanilla, lemon zest, and salt together until smooth and fluffy.

Step 3: Whip the Cream

In a separate bowl, whip cold heavy cream to soft peaks using a hand mixer. This gives the mousse its light texture.

Step 4: Fold Together

Gently fold the whipped cream into the cream cheese mixture in two stages. Use a spatula and light hand to maintain fluffiness.

Step 5: Flavor (Optional)

Swirl in melted chocolate, nut butter, or fruit puree if desired. Add visual appeal and extra flavor without added sugar.

Step 6: Chill

Spoon into ramekins or jars. Chill for at least 30 minutes. Flavors develop more as it rests.
