🍋 Cooking Time & Serving

• Total Time: 10 minutes (+ chilling)

• Servings: 4

🧾 Ingredients

• 1 cup heavy whipping cream

• 4 oz cream cheese, softened

• 1/4 cup powdered erythritol (or preferred keto-friendly sweetener)

• 2 tbsp fresh lemon juice (about half a lemon)

• 1 tsp lemon zest

• 1/2 tsp vanilla extract

👩‍🍳 How to Make Keto Lemon Mousse

Step 1: Whip the Cream
In a large bowl, use a hand or stand mixer to whip the heavy cream until stiff peaks form. Set aside.

Step 2: Beat the Cream Cheese
In another bowl, beat the softened cream cheese until smooth and creamy. Add powdered sweetener, lemon juice, lemon zest, vanilla extract, and a pinch of salt. Beat again until fully combined and smooth.

Step 3: Fold Together
Gently fold the whipped cream into the lemon-cream cheese mixture using a spatula. Fold until fully incorporated and smooth — try not to deflate the whipped cream too much.

Step 4: Chill (Optional)
Spoon the mousse into small serving glasses or bowls. Chill for at least 1 hour before serving for best texture and flavor. You can also enjoy it immediately if you prefer a softer mousse.

Step 5: Garnish & Serve
Top with extra lemon zest, a small dollop of whipped cream, or a few fresh berries if desired (keep in mind carb content). Serve chilled and enjoy!

📝 Notes

• Sweetener Options: Powdered erythritol works best for a smooth texture, but you can also use monk fruit or allulose. Avoid granular sweeteners as they may make the mousse gritty.

• Make It Ahead: This mousse holds up well in the fridge for up to 3 days. Great for meal prep!

• Additions: Want extra lemon kick? Add 1/4 tsp lemon extract along with the juice and zest.

• Serving Ideas: Serve in ramekins, small jars, or as a topping for keto pancakes or waffles.
