Lemon cheesecake mousse is a light and creamy dessert that combines the tangy flavor of lemon with the richness of cream cheese. This no-bake dessert is made by whipping together cream cheese, lemon juice, powdered sugar, and whipped cream until smooth and fluffy. It is then chilled to set and served with a dollop of whipped cream and a sprinkle of lemon zest for an extra burst of citrus flavor.
