Creating these Irresistible Raspberry Lemon Bars is straightforward if you follow these simple steps:

1. Preheat Oven: Preheat your oven to 350°F (175°C). Line an 8×8-inch baking dish with parchment paper, allowing some overhang for easy removal.
2. Make the Crust: In a medium bowl, mix together the flour and powdered sugar. Add the softened butter and blend until crumbly. Press the mixture into the bottom of the prepared baking dish to form an even layer.
3. Bake the Crust: Place the baking dish in the preheated oven and bake for 15 minutes, or until lightly golden.
4. Prepare the Filling: In a separate bowl, whisk together the granulated sugar, eggs, lemon juice, lemon zest, baking powder, and a pinch of salt until smooth and well combined.
5. Add Raspberries: Gently fold in the fresh raspberries, being careful not to break them.
6. Combine and Bake: Pour the filling over the pre-baked crust. Return the dish to the oven and bake for an additional 25-30 minutes, or until the filling is set and slightly firm to the touch.
7. Cool and Serve: Remove from the oven and let cool completely in the pan. Once cooled, lift the bars out using the parchment paper overhang and cut into squares. Dust with additional powdered sugar before serving if desired.

These steps will guide you in creating these incredible raspberry lemon bars effortlessly.
