Creating Blueberry Cream Cheese Bars is a straightforward process as long as you follow these simple steps:

1. Preheat the Oven: Begin by preheating your oven to 350°F (175°C). Prepare an 8×8-inch baking dish by greasing it lightly or lining it with parchment paper.

2. Make the Crust: In a medium bowl, combine 1 ½ cups of all-purpose flour, ½ cup of powdered sugar, and ½ teaspoon of salt. Add in ¾ cup of softened butter and mix until the mixture resembles coarse crumbs. Press this mixture evenly into the bottom of the prepared baking dish and bake for 15 minutes.

3. Prepare the Cream Cheese Layer: While the crust is baking, in another bowl, beat together 8 oz of softened cream cheese and 1 cup of granulated sugar until smooth. Add in 2 large eggs, 1 teaspoon of vanilla extract, and 2 tablespoons of flour. Mix until well combined.

4. Layer the Cream Cheese Mixture: Once the crust is done baking, remove it from the oven and pour the cream cheese mixture over the crust. Spread it evenly with a spatula.

5. Prepare the Blueberry Topping: In a separate bowl, toss 2 cups of fresh blueberries with 1 tablespoon of cornstarch and 2 tablespoons of granulated sugar. Sprinkle the blueberry mixture evenly over the cream cheese layer.

6. Bake the Bars: Return the baking dish to the oven and bake for an additional 30 to 35 minutes, or until the center is set and the top is lightly golden.

7. Cool and Slice: Remove the dish from the oven and allow it to cool for at least 1 hour at room temperature. Once cooled, slice into squares for serving.

8. Chill (Optional): For better texture and flavor, you can refrigerate the bars for a few hours before serving, but this is optional.
