Creating Tangy Raspberry Lemon Bars is a simple process if you follow these steps:

1. Preheat the Oven: Preheat your oven to 350°F (175°C). Grease an 8×8 inch baking dish.

2. Make the Crust: In a mixing bowl, combine flour, powdered sugar, softened butter, and salt. Mix until well combined, forming a crumbly dough. Press this mixture into the bottom of the prepared baking dish evenly.

3. Bake the Crust: Bake the crust in the preheated oven for 15-20 minutes until lightly golden. Remove from oven and let it cool slightly.

4. Prepare the Filling: In another bowl, whisk together eggs, granulated sugar, lemon juice, lemon zest, and salt until smooth. In a separate small bowl, toss raspberries with 2 tablespoons of flour to coat them.

5. Combine Layers: Pour the lemon filling over the cooled crust. Evenly distribute the floured raspberries on top of the lemon filling.

6. Bake: Return the dish to the oven and bake for another 25-30 minutes or until the filling is set but still slightly jiggly in the center.

7. Cool and Set: Remove from the oven and allow it to cool to room temperature. Once cooled, place in the refrigerator for at least 1-2 hours to set completely.

8. Slice: Once fully chilled and set, use a sharp knife to cut into squares or bars.

9. Dust with Powdered Sugar: Before serving, dust the tops with powdered sugar for an elegant finish.
