Beat the Cream Cheese: In a large mixing bowl, beat the softened cream cheese until smooth. This can be done using a hand mixer or a stand mixer.
Add Sweetener and Flavors: Add the ground erythritol, lemon juice, lemon rind (zest), and vanilla extract to the cream cheese. Whisk until the mixture is smooth and well combined.
Step 2: Whip the Cream
Whip the Cream: In a separate bowl, whisk the cream until firm peaks form. This can be done with a hand mixer or a stand mixer. Be careful not to overwhip, as this can turn the cream into butter.
Step 3: Combine Mixtures
Fold in the Whipped Cream: Gently fold the whipped cream into the cream cheese mixture. Use a spatula to mix until the two mixtures are well combined, but be careful to maintain the light and airy texture.
Step 4: Chill the Mousse
Chill: Transfer the mousse to serving dishes or a large bowl. Cover and chill in the refrigerator for at least 1 hour before serving. This allows the flavors to meld and the mousse to set properly.
