"These good old-fashioned lemon bars pack a punch of robust lemon flavor, without being either too tart or too sweet. They come together in minutes by hand and are so satisfying. A soft, flaky, buttery shortbread crust is the base for the golden yellow lemon filling that tops it. As they bake, the filling sets up into a gorgeous shade of yellow, and is dense yet light, smooth, and creamy. They're my favorite recipe for lemons bars me and remind me of the lemon bars my mom and grandma used to make...."
