Lemon bars are the bright, tangy answer to every chocolate-dominated dessert table. A thick layer of vibrant lemon curd — tangy, sweet, and intensely citrusy — sits atop a rich, buttery shortbread crust. Dusted with powdered sugar, they are as beautiful as they are delicious.
The shortbread base is sturdy enough to hold up to the lemon layer but tender enough to melt in your mouth. The lemon curd sets up just enough to slice cleanly while still having that luscious, silky quality that makes lemon desserts so irresistible.
These are the perfect dessert for spring gatherings, bridal showers, potlucks, or any time you need a dessert that is bright, refreshing, and not too heavy.

Use freshly squeezed lemon juice, never bottled, for the best flavor.
The filling will puff up during baking and flatten as it cools — this is normal.

Reheating
Lemon bars are served cold. No reheating needed.
Cooking Notes
Editor's Note
Give the unsalted butter softened and powdered sugar enough time to soften or concentrate without letting the seasoning fade. The flavor profile works best when the seasoning around the unsalted butter softened and powdered sugar feels clean rather than heavy. Avoid extending the oven time once the texture is right.
