Follow these simple steps to prepare your No Bake Lemon Blueberry Dessert:

1. Prepare the Crust: In a medium bowl, mix the crushed graham crackers, melted butter, and granulated sugar until well combined. Press the mixture firmly into the bottom of a 9-inch pie or tart pan to form the crust.

2. Make the Filling: In a large bowl, beat together the softened cream cheese and powdered sugar until smooth and creamy.

3. Add Flavors: Stir in the fresh lemon juice and lemon zest, mixing until well incorporated.

4. Fold the Whipped Cream: Carefully fold in the whipped cream, combining gently to maintain the lightness of the mixture.

5. Layer the Blueberries: Add a layer of fresh blueberries into the lemon filling, gently mixing to distribute them evenly.

6. Fill the Crust: Pour the lemon-blueberry filling over the prepared crust, smoothing the top with a spatula.

7. Chill: Cover the dessert with plastic wrap and place it in the refrigerator for at least 4 hours or overnight, allowing the flavors to meld and the filling to set.

8. Prepare Optional Topping: If desired, prepare a blueberry topping by simmering additional blueberries with cornstarch and a little sugar until the mixture thickens, then allow it to cool.

9. Serve: Once set, remove the dessert from the fridge. If using, top with the prepared blueberry mixture just before serving.

10. Slice and Enjoy: Cut into slices and serve chilled. Enjoy the refreshing taste of summer!
