Step 1: Prepare the Pan
Preheat oven to 350°F (175°C).
Line an 8x8 or 9x9-inch baking pan with parchment paper, leaving overhang for easy removal.
Step 2: Make the Buttery Crust
In a bowl, combine flour, powdered sugar, and salt.
Cut in cold butter using a pastry cutter or fingertips until mixture resembles coarse crumbs.
Press firmly and evenly into the bottom of the prepared pan.
Bake for 15–18 minutes, until lightly golden.
Do not overbake—the crust should just begin to turn golden.
Step 3: Prepare the Filling
In a bowl, whisk eggs and sugar until smooth.
Add flour and whisk until fully combined.
Stir in lemon juice and zest.
Gently fold in raspberries (lightly mash a few for a natural swirl effect).
Step 4: Bake the Bars
Pour filling over the warm crust.
Return to oven and bake for 20–25 minutes, until center is set and no longer jiggles.
Remove and cool completely at room temperature.
Step 5: Chill & Slice
Refrigerate for at least 2 hours before slicing.
Lift from pan using parchment overhang.
Dust with powdered sugar before serving.
For clean slices, use a sharp knife and wipe between cuts.
