Preheat the Oven:
Preheat your oven to 350°F (175°C). Grease a 9x13-inch baking pan and set aside.
Prepare the Crust:
In a large mixing bowl, cream together the softened butter and sugar until light and fluffy.
Gradually add the flour and salt, mixing until just combined.
Press the mixture evenly into the bottom of the prepared baking pan to form the crust.
Bake the Crust:
Bake the crust in the preheated oven for about 20 minutes or until it turns golden brown.
Make the Lemon Filling:
While the crust is baking, prepare the lemon filling.
In a separate bowl, whisk together the eggs, granulated sugar, flour, lemon zest, lemon juice, and baking powder until well combined.
Assemble and Bake:
Pour the lemon filling over the baked crust, spreading it evenly.
Return the pan to the oven and bake for an additional 25-30 minutes or until the filling is set and the edges are lightly golden.
Cool and Serve:
Allow the lemon bars to cool completely in the pan on a wire rack.
Once cooled, refrigerate for at least 2 hours to make cutting easier.
Garnish and Enjoy:
Dust the top with powdered sugar before serving, if desired.
Cut into squares and serve these luscious lemon bars for a delightful citrusy treat.
