Prepare the Graham Cracker Crust: Combine graham cracker crumbs, melted butter, and sugar in a mixing bowl. Press into a tart pan and refrigerate for at least one hour to set.

Make the Filling: In a stand mixer, beat cold heavy whipping cream with vanilla extract until stiff peaks form. Blend softened cream cheese, powdered sugar, lemon zest, and juice until smooth, then fold in whipped cream.

Assemble the Tart: Spread the filling over the chilled crust and arrange fresh fruit on top.

Chill Before Serving: Refrigerate the assembled tart for an additional hour to firm up the filling.
