If you have a lemon lover in your life, you are going to want to add these lemon bars to your baking list pronto! A lemon curd filling tops a perfectly baked shortbread crust, making the most delicious lemony dessert you will ever taste!
Preheat oven to 350 degrees F. Line a 9×13 pan with parchment and set aside. In a large bowl, combine the egg, butter and sugar. Mix until creamy.
Add flour and salt and stir until combined. Using your fingers (flour them, if needed), press the dough evenly into the bottom of the prepared pan. Bake in the preheated oven for 15 minutes.
MAKE THE FILLING
In a medium bowl, combine the sugar, flour, eggs, lemon juice and lemon zest. Whisk until lumps are gone. Pour over the crust and bake for an additional 20-25 minutes, or until the outer edges are lightly golden.
Once the bars have cooled, dust with powdered sugar and cut into squares. Store covered in the refrigerator.
