Lemon bars are a popular dessert made with a buttery shortbread crust and a tangy lemon filling. The filling typically consists of fresh lemon juice, sugar, eggs, and flour, which creates a smooth and zesty flavor. Once baked, they are often dusted with powdered sugar for added sweetness. These treats are usually cut into squares or rectangles, making them easy to serve and enjoy. Lemon bars are a favorite at picnics, potlucks, and family gatherings due to their refreshing taste and simple preparation. They can be served chilled or at room temperature, appealing to many dessert lovers.
