Ingredients

Scale
  • 1 ½ cups (150g) graham cracker crumbs
  • 6 tablespoons (85g) unsalted butter, melted
  • ¼ cup (50g) granulated sugar
  • 1 ½ cups (225g) fresh or frozen blueberries
  • 3 large eggs, room temperature
  • 1 ¼ cups (250g) granulated sugar
  • ½ cup (120ml) freshly squeezed lemon juice (about 34 lemons)
  • 2 tablespoons lemon zest
  • ½ cup (60g) all-purpose flour
  • ¼ teaspoon salt
  • Powdered sugar (optional, for dusting)

Instructions

  1. Preheat oven to 350°F (175°C). In a medium bowl, mix graham cracker crumbs, melted butter, and sugar until mixture resembles wet sand. Press firmly into the bottom of a greased 9×9-inch or 8×8-inch baking pan. Bake for 10 minutes, then remove and cool slightly.
  2. While crust bakes, whisk eggs and granulated sugar in a large bowl until smooth and slightly frothy, about 2-3 minutes. Add lemon juice, lemon zest, flour, and salt; mix gently until combined.
  3. Fold blueberries gently into the filling mixture. If using frozen, fold in without thawing to avoid breaking berries.
  4. Pour filling over warm crust and spread evenly. Bake for 25-30 minutes until filling is set and edges start to turn golden but center still jiggles slightly.
  5. Cool bars at room temperature for about 1 hour, then refrigerate at least 2 hours to fully set.
  6. Slice bars with a sharp knife dipped in hot water and wiped dry between cuts. Dust with powdered sugar if desired before serving.

Notes

Press the crust firmly before baking to ensure crunchiness. Use room temperature eggs for a smooth filling. Avoid overmixing after adding flour to prevent cracks. Chill bars completely before slicing for clean cuts. Fresh lemon juice is preferred for best flavor. For gluten-free, substitute flour with almond or gluten-free flour. For dairy-free, use coconut oil instead of butter.
