Creating Lemon Blueberry Cheesecake Bars is straightforward if you follow these simple steps:

1. Preheat oven: Preheat your oven to 325°F (165°C). Line an 8×8 inch baking dish with parchment paper, leaving some overhang on the sides for easy removal later.
2. Prepare the crust: In a bowl, combine the flour, granulated sugar, and melted butter. Mix until crumbly. Press this mixture firmly into the bottom of the prepared baking dish.
3. Bake the crust: Place the crust in the preheated oven and bake for 10 minutes. Remove from oven and let it cool slightly.
4. Make the filling: In a mixing bowl, beat the cream cheese until smooth. Gradually add the powdered sugar, mixing until well combined.
5. Add eggs and flavor: Beat in the eggs, lemon juice, lemon zest, and vanilla extract until the mixture is smooth and creamy. Ensure there are no lumps.
6. Incorporate blueberries: Gently fold the blueberries into the cheese mixture, being careful not to break them apart.
7. Combine layers: Pour the cheesecake filling over the cooled crust, spreading it evenly.
8. Bake: Return to the oven and bake for an additional 30-35 minutes or until the filling is set in the center and the edges are lightly browned.
9. Cool completely: Once done, take out the baking dish and allow it to cool at room temperature for about an hour. Afterward, place it in the refrigerator for at least 2 hours, or until completely chilled.
10. Serve: Once the cheesecake bars are cool, use the parchment overhang to lift them out of the dish. Cut into squares and serve.

Following these steps will guide you in creating these incredible cheesecake bars effortlessly.
