Creating these delightful Blueberry Cream Cheese Bars is easy if you follow these steps carefully:

1. Preheat the Oven: Set your oven to 350°F (175°C) and line an 8×8-inch baking dish with parchment paper, allowing some overhang for easy removal later.

2. Make the Crust: In a medium bowl, combine flour, granulated sugar, melted butter, and salt. Mix until it forms a crumbly texture.

3. Press the Crust: Press the mixture evenly into the bottom of your prepared baking dish. Bake the crust for about 10-12 minutes or until lightly golden.

4. Prepare the Filling: While the crust is baking, beat the softened cream cheese and powdered sugar in a separate bowl until smooth and creamy.

5. Add Egg and Flavorings: Add the egg, vanilla extract, lemon juice, and lemon zest to the cream cheese mixture. Beat until fully incorporated and smooth.

6. Fold in Blueberries: Gently fold in the fresh blueberries, being careful not to break them.

7. Spread the Filling: Pour the cream cheese filling over the pre-baked crust, spreading it evenly.

8. Bake: Return the dish to the oven and bake for an additional 25-30 minutes, or until the edges look set and the center is slightly jiggly but not liquid.

9. Cool the Bars: Allow the bars to cool completely in the baking dish on a wire rack. Once cooled, refrigerate for 1 hour.

10. Slice and Serve: Use the parchment overhang to lift the bars out of the pan. Cut into squares and serve chilled or at room temperature.
