This recipe produces delicious lemon bars, but baking time may vary depending on your oven. It's better to slightly overbake than underbake. After baking, sprinkle powdered sugar on top.

Unlike a standard single-layer butter cake that relies solely on leavening agents for its structure, these citrus squares depend on the precise coagulation of whole eggs to transform a fluid juice-and-sugar mixture into a cohesive, sliceable curd. The heavy proportion of acid from the fresh lemon juice lowers the overall pH of the filling, which actually weakens the protein network of the eggs during baking, requiring careful temperature management to achieve the correct set. Controlling this thermal reaction ensures the final texture remains creamy rather than watery or rubbery.
Proper refrigeration for at least four hours firms the fats within both the crust and the filling, yielding clean, sharp corners upon slicing. Precision in these foundational thermal steps guarantees professional results from your home kitchen.
