Ingredients
  

Crust Ingredients

  • 1.5 cups All-Purpose Flour Provides structure and a tender crumb.
  • 0.5 cups Granulated Sugar Adds sweetness to the crust.
  • 0.5 cups Unsalted Butter Softened for richness and moisture.
  • 1 pinch Salt Enhances flavors.

Filling Ingredients

  • 4 large Eggs Main binding agent for the filling.
  • 1 cup Granulated Sugar Sweetens the lime juice.
  • 0.5 cups Fresh Key Lime Juice Gives the bars their signature flavor.
  • 2 pieces Limes (zest) Adds intense citrus aroma and flavor.
  • 0.25 cups All-Purpose Flour Helps stabilize the filling.

Instructions
 

  • Preheat your oven to 350°F (175°C).
  • In a medium bowl, combine 1 ½ cups of all-purpose flour, ½ cup of granulated sugar, and a pinch of salt. Whisk until fully incorporated.
  • Add ½ cup of softened unsalted butter to the dry mixture. Blend until the mixture resembles coarse crumbs.
  • Press the mixture into the bottom of a greased 9x9 inch baking pan evenly.
  • Bake the crust for 20 minutes or until lightly golden.
  • In a large mixing bowl, whisk together 4 large eggs until well beaten. Gradually add in 1 cup of granulated sugar, whisking until combined.
  • Add ½ cup of fresh key lime juice and the zest from 2 limes to the egg mixture. Whisk until well combined.
  • Sprinkle ¼ cup of all-purpose flour into the mixture and gently fold it in.
  • Pour the filling over the pre-baked crust and spread it evenly.
  • Return the pan to the oven and bake for an additional 20-25 minutes, or until the filling is set and slightly jiggly in the center.
  • Allow the pan to cool at room temperature for about an hour, then transfer to the refrigerator to chill for at least two hours.
  • Cut the bars into squares and dust with powdered sugar if desired. Serve chilled.

Notes
