These Zesty Lemon Squares are a delightful treat with a buttery crust and a tangy lemon filling, perfect for any occasion.
Preheat your oven to 350°F (175°C).
Preheating ensures even baking from the start.
In a mixing bowl, combine the flour, butter, and powdered sugar for the base.
Use cold butter to achieve a crumbly texture.
Press the mixture evenly into a 13 x 9-inch baking pan.
Ensure an even layer for consistent baking.
Bake the crust for 20-25 minutes or until lightly golden.
Keep an eye on the crust to prevent over-browning.
In another bowl, whisk together the eggs, sugar, lemon juice, flour, baking powder, and lemon rind for the filling.
Whisk until the mixture is smooth and well combined.
Pour the filling over the cooled crust.
Ensure the crust is completely cooled to avoid mixing layers.
Bake again at 350°F for 25 minutes or until the filling is set.
The filling should be firm but slightly jiggly in the center.
Let the lemon squares cool completely, then sprinkle with powdered sugar.
Use a sifter for an even dusting of powdered sugar.
Cut into squares and serve.
Use a sharp knife for clean edges.
