Instructions
 

Preparation

  • Preheat your oven to 350°F (175°C).
  • In a mixing bowl, combine 1 cup flour, softened butter, 1/4 cup sugar, and salt. Mix until it resembles a crumbly dough.
  • Press this mixture firmly into the bottom of an 8×8 inch baking dish to create the crust.
  • Bake for 15-20 minutes, or until lightly golden.

Filling

  • In another bowl, whisk together 2 large eggs, 1 cup sugar, lemon juice, lemon zest, 1/4 cup flour, and baking powder until smooth and well combined.
  • Pour the lemon filling over the baked crust.
  • Return to the oven and bake for an additional 20-25 minutes, until the filling is set.

Finishing Touches

  • Allow the bars to cool completely before dusting with powdered sugar and serving.

Notes

For the best results, ensure your butter is softened, not melted. You can substitute fresh lemon juice and zest with bottled versions, but fresh offers a better flavor. These bars can be served with whipped cream or ice cream.
