In a mixing bowl, combine the graham cracker crumbs and melted butter. Stir until fully mixed and crumbled.
In another bowl, beat the softened cream cheese until smooth. Gradually add in the powdered sugar and vanilla extract, mixing until creamy.
In a separate bowl, whip the heavy cream until soft peaks form. Gently fold the whipped cream into the cream cheese mixture until combined.
In a small bowl, mash half of the raspberries and mix in the lemon juice and lemon zest to create a purée.
In serving glasses or parfait cups, layer the ingredients: start with a layer of graham cracker crumbs, followed by a layer of the cream cheese mixture, then a layer of the raspberry purée.
Repeat the layers until the glasses are filled, finishing with a layer of the cream cheese mixture on top.
Garnish with the remaining fresh raspberries and a sprinkle of lemon zest.
Notes
Serve the parfaits chilled, with a mint leaf on top for added color and freshness.
