Creating Blueberry Cream Cheese Bars is straightforward when you follow these simple steps:

1. Preheat the Oven: Preheat your oven to 350°F (175°C). Line an 8×8 inch baking dish with parchment paper for easy removal.

2. Make the Crust: In a medium bowl, mix together the flour, granulated sugar, softened butter, and salt. Press this mixture evenly into the bottom of the prepared baking dish to form the crust.

3. Bake the Crust: Place the crust in the preheated oven and bake for 10-12 minutes or until lightly golden.

4. Prepare the Filling: In a large bowl, beat the softened cream cheese with powdered sugar until creamy. Add the egg, lemon juice, and vanilla extract, mixing until smooth.

5. Incorporate Blueberries: Gently fold in the blueberries, taking care not to break them.

6. Spread Filling: Pour the cream cheese mixture over the baked crust, spreading it evenly.

7. Bake Again: Return the dish to the oven and bake for an additional 25-30 minutes or until the filling is set and lightly puffed.

8. Cool: Once baked, remove from the oven and allow to cool in the dish for about 10 minutes. Then, transfer to a wire rack and let cool completely.

9. Slice: After cooling, slice into squares or bars as desired.

10. Chill (Optional): For a refreshing taste, chill in the refrigerator for about 1 hour before serving.

These steps will guide you effortlessly in creating these delicious Blueberry Cream Cheese Bars.
