Let’s dive into the process of creating these scrumptious bars. As always, I encourage a little improvisation, just like my mother taught me.

1. Preheat your oven to 350°F (175°C) and line an 8×8-inch baking dish with parchment paper, leaving some overhang on the sides to easily lift the bars out later.
2. In a medium bowl, combine the flour, granulated sugar, and a pinch of salt. Pour in the melted butter and stir until the mixture resembles coarse crumbs.
3. Press this mixture firmly into the bottom of the prepared baking dish, creating an even base layer. Bake for 10-12 minutes, or until lightly golden. Let cool slightly.
4. While the crust is cooling, beat the cream cheese in a large bowl until smooth. Add the egg, vanilla extract, and powdered sugar, mixing until fully incorporated and creamy.
5. Spread the cream cheese mixture over the cooled crust, smoothing it out with a spatula.
6. Evenly distribute the blueberries over the cream cheese layer, gently pressing them into the mixture.
7. Bake for an additional 25-30 minutes, or until the edges are set and the center still has a slight jiggle.
8. Allow the bars to cool to room temperature, then refrigerate for at least 2 hours before slicing into bars.

Remember, patience is key here—letting the bars chill completely ensures they set beautifully and are much easier to slice.
