In a medium bowl, combine the sliced strawberries with a tablespoon of powdered sugar. Mix gently and let sit for about 10-15 minutes to macerate, allowing the strawberries to release their juices.
In a large mixing bowl, beat the heavy whipping cream with the remaining powdered sugar and vanilla extract until soft peaks form.
In another bowl, combine the softened cream cheese, lemon juice, and lemon zest. Beat until smooth and creamy. Gently fold in one cup of the whipped cream until just combined.
To assemble the cake, start by spreading a thin layer of the cream cheese mixture at the bottom of an 8x8 inch dish.
Place a layer of graham crackers over the cream mixture, breaking them to fit if necessary.
Spread another layer of the cream cheese mixture on top of the crackers, followed by a layer of the macerated strawberries.
Repeat the layers (graham crackers, cream cheese mixture, strawberries) until all ingredients are used, finishing with a layer of the whipped cream on top.
Cover the dish with plastic wrap and refrigerate for at least 4 hours, preferably overnight, to let the flavors meld and the cake firm up.
Before serving, garnish with additional fresh strawberries and a sprinkle of lemon zest on top for a refreshing touch.
Notes
Serve chilled slices on dessert plates and garnish with mint leaves for an extra fresh look.
