Classic Lemon Bars

Featured in: Golden Desserts

These lemon bars feature a crisp, buttery shortbread crust paired with a bright, tangy lemon filling. The base is baked first until golden, then topped with a smooth mixture of fresh lemon juice, zest, eggs, and sugar before a final bake sets the filling. Once cooled and chilled, the bars are dusted with powdered sugar and cut into squares, making a perfect balance of citrus and sweetness with a tender, flaky crust. Ideal for teatime or simple dessert moments.
