Making these Tangy Raspberry Lemon Bars is as easy as following these clear steps:

1. Preheat the Oven: Start by preheating your oven to 350°F (175°C). Grease a 9×13-inch baking dish for the bars.
2. Prepare the Crust: In a large mixing bowl, cream together the softened butter and granulated sugar until light and fluffy.
3. Add Dry Ingredients: Gradually mix in the flour and salt, followed by the vanilla extract. The mixture will be crumbly.
4. Press into the Pan: Evenly press the crust mixture into the bottom of the prepared baking dish. Bake for about 15-20 minutes or until lightly golden.
5. Make the Filling: In another bowl, whisk together the granulated sugar, eggs, lemon juice, lemon zest, and flour until smooth.
6. Add Raspberries: Gently fold in the raspberries, being careful not to crush them too much.
7. Combine Filling and Crust: Pour the filling over the pre-baked crust.
8. Bake Again: Return the dish to the oven and bake for 30-35 minutes, or until the filling is set and the edges are lightly golden.
9. Cool: Remove from the oven and allow to cool in the dish for about an hour. Then, transfer to the refrigerator to cool completely for at least another hour.
10. Dust and Serve: Once fully cooled, dust the top with powdered sugar before slicing into bars.

These straightforward steps will ensure you create the most delicious Tangy Raspberry Lemon Bars that are sure to impress everyone!
