Ingredients

Scale
  • 2 cups (250g) all-purpose flour
  • ½ cup (100g) granulated sugar
  • ¼ tsp salt
  • ¾ cup (170g) cold unsalted butter, cubed
  • ½ cup (120ml) fresh lemon juice (about 3 medium lemons)
  • 1 tbsp lemon zest
  • 1 cup (200g) granulated sugar
  • 4 large eggs, room temperature
  • ¼ cup (30g) all-purpose flour
  • 1 ½ cups (225g) fresh blueberries
  • Powdered sugar, for dusting (optional)

Instructions

  1. Preheat oven to 350°F (175°C). In a large bowl, whisk together 2 cups flour, ½ cup sugar, and ¼ tsp salt. Add ¾ cup cold, cubed butter and blend until mixture resembles coarse crumbs. Press firmly into bottom of 9×13 inch sheet pan. Bake 15–18 minutes until edges start to turn golden. Let cool slightly.
  2. In a medium bowl, whisk 1 cup sugar and ¼ cup flour. Add 4 eggs one at a time, whisking well after each. Stir in ½ cup lemon juice and 1 tbsp lemon zest until smooth and slightly thickened. Pour over pre-baked crust.
  3. Scatter 1 ½ cups blueberries evenly over lemon filling, gently pressing down so they stick but don’t sink.
  4. Bake for 25–30 minutes at 350°F (175°C) until filling is set but slightly jiggly in center. Avoid overbaking.
  5. Cool bars completely in pan on wire rack for at least 1 hour. Cover and chill in refrigerator for 2 hours or overnight for clean cuts.
  6. Using a sharp serrated knife, cut into squares, wiping knife clean between cuts. Dust with powdered sugar if desired and serve chilled or at room temperature.

Notes

Chill bars completely before slicing to get clean cuts. Use a serrated knife and wipe clean between cuts. Toss blueberries in flour before adding to prevent sinking. Tent crust with foil if browning too fast. Avoid overbaking to prevent rubbery lemon layer.
