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 enjoyed for their refreshing taste and are commonly served at gatherings, picnics, and parties. Lemon bars can be cut into squares or rectangles, making them easy to share. They are a delightful combination of sweet and sour, appealing to many dessert lovers.
