Follow these simple steps to create your own batch of Lemon Bars:

1. Preheat your oven to 350°F (175°C). Grease an 8×8-inch baking dish or line it with parchment paper for easy removal.
2. In a medium bowl, mix together 1 cup flour, softened butter, and 1/4 cup sugar until the mixture resembles coarse crumbs. Press the mixture into the prepared baking dish to form the crust.
3. Bake the crust in the preheated oven for 15-20 minutes, or until lightly golden. Let it cool slightly while you prepare the lemon filling.
4. In another bowl, whisk together 1 cup sugar, eggs, 1/4 cup flour, lemon juice, lemon zest, baking powder, and salt until smooth and well combined.
5. Pour the lemon mixture over the warm crust and return the dish to the oven. Bake for an additional 20-25 minutes, or until the filling is set and slightly golden on top.
6. Allow the bars to cool completely in the pan. Once cooled, dust the top with powdered sugar before slicing into squares.

A tip from my kitchen: use a microplane to zest the lemons finely, ensuring every bite is infused with that zesty aroma.
