Lime Shortbread Bars Recipe

Adapted from Three Many Cooks


  • 1 cup all-purpose flour
  • 1/8 teaspoon salt
  • 1/2 cup powdered sugar
  • 1 stick unsalted butter, melted and cooled
  • 2 large eggs
  • 3/4 cup granulated sugar
  • 1 1/2 tablespoons all-purpose flour
  • 6 tablespoons lime juice (about 3 medium limes)
  • 2 teaspoons finely grated lime zest
  • Powdered sugar for dusting, if desired


  1. Heat oven to 325°F and arrange rack to lower-middle. Spray and 8 x 8-inch pan with cooking spray and line with a piece of foil long enough so two sides stick up about 2-inches above the sides of the pan and act as handles. Spray foil with cooking spray.
  2. Combine 1 cup flour, salt, and powdered sugar in a medium bowl; stir in butter until moistened throughout. Press dough into pan and even out using the bottom of a measuring cup dipped in flour. Bake until pale golden, about 20-25 minutes.
  3. Meanwhile, whisk eggs, sugar, 1 1/2 tablespoons flour, lime juice and lime zest in a medium bowl until smooth. Remove pan from oven and add lime mixture. Continue baking until just set, about 15-20 minutes. Let cool in pan for a few minutes then run a knife around outer edges of pan. Using foil, pull bars from pan and set on a wire rack to cool to room temperature. Cut into squares, dust with powdered sugar and serve.
