Step 1: Prepare the Crust

1. Mix Crust Ingredients: In a medium bowl, combine the graham cracker crumbs, melted butter, and granulated sugar. Mix until well combined.
2. Press into Pan: Press the mixture firmly into the bottom of a 9×9-inch baking dish to form an even layer. Set aside.

Step 2: Make the Creamy Layer

1. Whip Cream: In a large bowl, whip the heavy cream until soft peaks form. Set aside.
2. Mix Cream Cheese: In another bowl, beat the softened cream cheese until smooth. Gradually add the powdered sugar, lemon juice, lemon zest, and vanilla extract, mixing until well combined.
3. Fold in Whipped Cream: Gently fold the whipped cream into the cream cheese mixture until fully incorporated.

Step 3: Assemble the Dessert

1. Spread Creamy Layer: Pour the creamy layer over the prepared crust and spread it evenly. Smooth the top with a spatula.
2. Chill: Cover the dish with plastic wrap and refrigerate for at least 4 hours or until set.

Step 4: Prepare the Blueberry Topping

1. Combine Blueberries: In a small bowl, combine the fresh blueberries, granulated sugar, and lemon juice. Gently toss to coat the blueberries.
2. Let Sit: Allow the mixture to sit for about 15 minutes to release juices.

Step 5: Serve

1. Top with Blueberries: Once the creamy layer is set, remove the dessert from the refrigerator and top with the blueberry mixture.
2. Slice and Enjoy: Cut into squares and serve chilled.
