This mousse is wonderfully airy and tangy, balancing the bright citrus punch of fresh lemon with rich creaminess from whipped heavy cream or cream cheese. It’s naturally low in carbs, using keto-friendly sweeteners like erythritol or monk fruit to keep it guilt-free. The texture is fluffy yet smooth, making it a delightful way to finish any meal or enjoy as a refreshing snack. Because it’s no-bake and requires just a handful of ingredients, it’s super quick to prepare—ideal for keto dieters craving a light dessert without added sugars.

Keto Lemon Mousse Recipe

Ingredients:

• 1 cup heavy whipping cream

• 3 tbsp powdered erythritol or your preferred keto sweetener

• 2 tbsp fresh lemon juice (about 1 lemon)

• 1 tsp lemon zest

• 3 oz cream cheese, softened (optional for extra creaminess and texture)

• 1 tsp vanilla extract

Instructions:

1. In a large mixing bowl, whip the heavy cream with powdered erythritol and vanilla extract until soft peaks form.

2. If using, beat the softened cream cheese separately until smooth. Gently fold the cream cheese into the whipped cream for a richer texture.

3. Add lemon juice and zest to the whipped mixture, folding gently to combine evenly without deflating the cream.

4. Spoon the mousse into serving dishes or glasses. Chill in the refrigerator for at least 1 hour to let it set and flavors meld.

5. Serve cold, garnished with extra lemon zest or a few fresh berries if desired.

Tips & Variations

• For a lighter mousse, omit cream cheese and use just whipped cream.

• Adjust sweetness or lemon juice to taste—more lemon for tangier mousse, more sweetener for a sweeter dessert.

• Garnish with fresh mint leaves or a thin lemon slice for a fancy touch.

• Make it dairy-free by substituting coconut cream for heavy cream and omitting cream cheese.
