Making Lemon Bars can be straightforward if you follow these simple steps:

1. Preheat Oven: Preheat your oven to 350°F (175°C). Grease a 9×9 inch square baking dish or line it with parchment paper.
2. Prepare Crust: In a medium bowl, combine melted butter, 1 cup flour, and 1/2 cup sugar. Mix until crumbly, then press into the bottom of the prepared dish. Bake for 15 minutes.
3. Make Filling: In a separate bowl, whisk together the eggs, 1 cup sugar, 2 tablespoons flour, baking powder, lemon juice, and lemon zest until well blended.
4. Combine & Pour: Once the crust is slightly golden, remove it from the oven. Pour the lemon filling over the hot crust.
5. Bake Again: Return to the oven and bake for 20-25 minutes or until the filling is set and no longer jiggles.
6. Cool: Remove from the oven and let cool at room temperature before refrigerating for at least 1 hour.
7. Slice: Once completely cool, dust with powdered sugar. Slice into squares or bars to serve.
