Keto Nutrition Breakdown
-
Net Carbs: ~3g per serving
-
Fat: High in healthy fats from cream cheese and heavy cream

Bonus: Lemons are rich in vitamin C, potassium, and B6, making this mousse not just tasty—but nutritious too!
Tips for Success
-
Avoid Overwhipping – Stop whipping cream once soft peaks form to prevent it from turning grainy.
-
Adjust Lemon Strength – Prefer a bolder lemon punch? Use up to ¾ cup of lemon curd. For a gentler flavor, stick to ½ cup.
-
Use Mascarpone for a Twist – Swap cream cheese for mascarpone for a silkier, slightly sweeter version with fewer carbs.
-
No Swerve? – Powdered erythritol works just as well.
