For the Shortbread Base:

  • 2 cups all-purpose flour
  • 1/4 teaspoon salt

For the Key Lime Filling:

  • 4 large eggs
  • 1 1/2 cups granulated sugar
  • 1/2 cup key lime juice (freshly squeezed if possible) 🍈
  • 1/4 cup all-purpose flour
  • 1/2 teaspoon baking powder
  • Zest of 2 key limes

For Dusting (Optional):

  • Powdered sugar for dusting


  1. Preheat Oven: Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish and line it with parchment paper for easy removal.
  2. Prepare Shortbread Base:
  • In a large bowl, cream together the softened butter and granulated sugar until light and fluffy.
  • Add the flour and salt, mixing until just combined. The mixture should resemble coarse crumbs.
  • Press the shortbread mixture evenly into the bottom of the prepared baking dish.
  1. Bake Shortbread Base:
  • Bake the shortbread base in the preheated oven for 15-18 minutes or until the edges are lightly golden. Remove from the oven and allow it to cool slightly.
  1. Prepare Key Lime Filling:
  • In a separate bowl, whisk together the eggs and granulated sugar until well combined.
  • Add the key lime juice, flour, baking powder, and key lime zest. Whisk until smooth.
  1. Pour Filling Over Shortbread:
  • Pour the key lime filling over the partially baked shortbread base, spreading it evenly.
  1. Bake to Perfection:
  • Return the baking dish to the oven and bake for an additional 20-25 minutes or until the center is set and the top is lightly golden.
  1. Cool and Chill:
  • Allow the Key Lime Shortbread Bars to cool in the baking dish. Once cooled, refrigerate for at least 2 hours to enhance the flavor and make the bars easier to cut.
  1. Dust with Powdered Sugar (Optional):
  • If desired, dust the top of the chilled bars with powdered sugar just before serving for a touch of elegance.
  1. Slice and Serve:
  • Using the parchment paper, lift the chilled bars out of the baking dish and onto a cutting board. Cut into squares or bars.
  1. Serve and Enjoy:
    • Serve the Key Lime Shortbread Bars chilled. These bars are perfect for a refreshing dessert on a warm day.
