Ingredients
For the Blueberry Mousse
- 1 cup fresh blueberries
- 8 ounces (225g) cream cheese, softened
- 1 cup heavy whipping cream
- ⅓ cup powdered erythritol or preferred keto sweetener
- 1 teaspoon vanilla extract
- 1 teaspoon fresh lemon juice
- ½ teaspoon lemon zest
- Pinch of salt
Optional Garnish
- Fresh blueberries
- Whipped cream
- Lemon zest
- Fresh mint leaves
- Sugar-free white chocolate shavings
Instructions
Step 1: Prepare the Blueberries
Wash and dry the blueberries thoroughly.
Place them in a small saucepan with the lemon juice over medium heat for about 5 minutes, stirring occasionally until the berries soften and release their juices.
Allow the mixture to cool completely.
Blend until smooth, then strain through a fine-mesh sieve if you prefer an extra-smooth mousse.
Step 2: Prepare the Cream Cheese Mixture
In a large mixing bowl, beat the softened cream cheese until completely smooth.
Add the powdered keto sweetener, vanilla extract, lemon zest, and a pinch of salt.
Mix until light and creamy.
Step 3: Add the Blueberry Puree
Pour the cooled blueberry puree into the cream cheese mixture.
Beat until the mixture is evenly colored and smooth.
Scrape down the sides of the bowl as needed.
Step 4: Whip the Cream
In a separate chilled bowl, whip the heavy cream until stiff peaks form.
Avoid overwhipping, which can make the cream grainy.
Step 5: Fold Everything Together
Using a rubber spatula, gently fold the whipped cream into the blueberry mixture.
Fold slowly to preserve the light, airy texture.
Continue until no white streaks remain.
Step 6: Chill
Divide the mousse evenly among six serving glasses or dessert bowls.
Cover each serving with plastic wrap.
Refrigerate for at least 2 hours to allow the mousse to firm up and develop its flavor.
Step 7: Garnish and Serve
Before serving, top each mousse with whipped cream, fresh blueberries, lemon zest, and mint leaves if desired.
Serve chilled for the best flavor and texture.
Tips for Perfect Keto Mousse
- Use room-temperature cream cheese to prevent lumps.
- Chill the mixing bowl before whipping the cream for faster results.
- Fold the whipped cream gently to keep the mousse light and fluffy.
- Taste the mixture before chilling and adjust the sweetener if needed.
- Fresh blueberries provide the best flavor, but frozen blueberries can also be used after thawing and draining.

Try these delicious variations:
- Add a tablespoon of unsweetened cocoa powder for a chocolate-blueberry mousse.
- Mix in crushed keto cookies for extra texture.

- Top with chopped pecans, walnuts, or almonds for a satisfying crunch.
Storage Instructions
Store the mousse covered in the refrigerator for up to 4 days.
Do not leave it at room temperature for more than 2 hours.
For longer storage, freeze individual portions for up to 1 month. Thaw overnight in the refrigerator before serving.
