Making Blueberry Cream Cheese Bars is straightforward when you follow these simple steps:

1. Preheat Oven: Start by preheating your oven to 350°F (175°C). Grease a 9×9-inch baking dish or line it with parchment paper for easy removal.
2. Prepare the Crust: In a medium bowl, whisk together the flour, granulated sugar, baking powder, and salt. Stir in the melted butter until crumbly. Press this mixture evenly into the bottom of the prepared baking dish.
3. Bake the Crust: Place the crust in the preheated oven and bake for 10 minutes, until slightly golden.
4. Make the Filling: While the crust is baking, in a large bowl, beat the softened cream cheese and powdered sugar until smooth. Add the eggs one at a time, mixing well after each addition. Stir in the vanilla extract.
5. Add the Blueberries: Gently fold in the blueberries into the cream cheese mixture. Be careful to not crush them.
6. Combine Layers: Pour the blueberry cream cheese mixture over the baked crust, spreading it evenly with a spatula.
7. Bake Again: Return the dish to the oven and bake for an additional 30-35 minutes, or until the center is set and the edges are lightly browned.
8. Cool: Remove from the oven and let the bars cool in the baking dish. Once at room temperature, transfer to the refrigerator and allow them to chill for at least one hour.
9. Cut and Serve: Once chilled, cut into squares to serve.

These simple steps will guide you through the process, ensuring your bars turn out perfectly delicious every time!
