Using a citrus juicer, juice the two lemons and set the juice aside.
Beat the softened cream cheese on medium-high with an electric hand mixer or stand mixer until creamy, smooth, and lump-free.
Add the heavy whipping cream and powdered sweetener to the cream cheese and mix at medium-high speed until creamy, fluffy, and soft peaks begin to form.
Add the fresh-squeezed lemon juice and salt, and continue to whip on medium speed to achieve a fluffy mousse texture. Do not overwhip.
Divide the mousse evenly into dessert glasses or bowls and garnish with optional lemon zest, berries, and sugar-free whipped cream. Serve.
Notes
Storage—Any leftover mousse can be stored in a sealed container in the fridge for up to 4 days. Do not freeze, as freezing and thawing will change the texture of the mousse.Notes—If you use an 8-inch or 9-inch pan, you can also use the keto lemon mousse as a pie filling.*All Nutritional Data Are Estimates Only Based on the Products I Used.Yield- 6 Servings, Serving Size: 2.5 ounces, Net Carbs per Serving: 4g, Amounts Per Serving
