In a large mixing bowl, beat together softened cream cheese and powdered sugar until smooth and creamy. Fold in 1 cup of whipped topping gently.
In a separate bowl, whisk together instant lemon pudding mix and cold milk until thickened.
Assemble the lasagna by spreading the lemon cream layer over the graham cracker crust, followed by the lemon pudding mixture, fresh blueberries, and remaining whipped topping.
Cover and chill in the refrigerator for at least 4 hours before serving.
