Creating Blueberry Cream Cheese Bars involves several straightforward steps. Follow these instructions to ensure perfect results every time:

1. Preheat the Oven: Preheat your oven to 325°F (163°C). Line an 8×8-inch baking dish with parchment paper for easy removal later.

2. Make the Crust: In a bowl, combine flour, granulated sugar, softened butter, and salt. Mix until crumbly and press it firmly into the bottom of the prepared baking dish to form an even layer.

3. Bake the Crust: Place the crust in the preheated oven and bake for 15 minutes, until it’s lightly golden. Remove and let it cool.

4. Prepare the Cream Cheese Filling: In a mixing bowl, beat softened cream cheese, granulated sugar, and vanilla extract until smooth and creamy.

5. Add Eggs: Add the eggs, one at a time, to the cream cheese mixture, beating well after each addition.

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

7. Combine Mixtures: Pour the cream cheese filling over the cooled crust, spreading it evenly with a spatula.

8. Bake Again: Return the baking dish to the oven and bake for an additional 30-35 minutes, or until the filling is set and slightly puffed up.

9. Cool Completely: Once baked, remove from the oven and let it cool in the pan. For best results, let the bars cool in the fridge for at least one hour before slicing.

10. Slice and Enjoy: Once chilled, lift the bars out of the baking dish using the parchment paper. Cut into squares and serve.
