Pour the cold heavy cream into a bowl and beat with an electric mixer until stiff peaks form, about 2 to 3 minutes. Set aside in the refrigerator.

In a separate large bowl, beat the softened cream cheese with powdered sugar, lemon juice, lemon zest, and vanilla extract until completely smooth and slightly fluffy. Scrape the bowl once to remove any hidden streaks.

Stir about one third of the whipped cream into the lemon base to loosen it. Add the remaining whipped cream and fold with a rubber spatula until no white streaks remain. Do not stir vigorously.

Spoon or pipe the mousse into small dessert glasses or jars. Refrigerate for at least 2 hours so the flavors meld and the texture firms.

Top with fresh berries, a pinch of lemon zest, graham cracker crumbs, or mint leaves just before serving.
