1-Getting Started: Begin by preheating your oven to 325 degrees F and preparing an 8-inch by 8-inch pan by lining it with parchment paper or greasing it well. This sets the stage for a smooth baking experience, ideal for home cooks looking to impress.

2-Making the Crust: Cream the butter and powdered sugar together until light and fluffy using a mixer.

Add the flour and salt, and mix just until combined, then press the crust mixture into the bottom of the prepared pan.

Bake the crust at 350 degrees F for 20 minutes or until barely golden to create a solid base for your filling.

3-Preparing the Filling: While the crust bakes, mix the sugar, flour, baking powder, eggs, and lime juice together in the same bowl without cleaning it. For an extra touch, you can add a drop of green food coloring for a pale green hue. This step highlights the importance of using room-temperature ingredients to improve texture and blending.

4-Baking and Finishing: Pour the filling over the partially baked crust and return the pan to the oven.

Bake for another 20-25 minutes, until a toothpick inserted in the center comes out clean and there’s a slight jiggle in the center.

Allow the bars to cool completely, as they will continue to set, then cut into squares and dust with powdered sugar before serving.
