Ingredients

Units Scale

For the Buttery Crust

  • 1 cup unsalted butter, softened
  • 1/2 cup powdered sugar
  • 2 cups all-purpose flour

For the Key Lime Filling

  • 1 can (14 oz) sweetened condensed milk
  • 1/2 cup fresh key lime juice
  • 1 tablespoon key lime zest

For Garnish (Optional)

  • Powdered sugar for dusting
  • Toasted shredded coconut
  • Lime zest curls or thin lime wheels
  • Fresh mint leaves

Instructions

  1. Prepare the Buttery Crust: Combine softened butter, powdered sugar, and all-purpose flour in a mixing bowl. Use a fork or mixer to blend until a crumbly dough forms. Press the mixture evenly into a greased baking dish to form a firm, even layer that will bake into a crunchy base.
  2. Bake the Crust: Bake the crust in a preheated oven at 350°F (175°C) for 15 to 20 minutes until the edges turn golden brown, developing a rich, crisp texture.
  3. Make the Key Lime Filling: While the crust bakes, whisk together sweetened condensed milk, fresh key lime juice, and key lime zest until smooth and well combined. The acidity will thicken the filling and enhance the citrus flavor.
  4. Add the Filling and Chill: Pour the lime filling over the warm crust, spreading it evenly. Refrigerate for at least 3 hours or until the filling is firm and cool enough to slice.
  5. Serve and Enjoy: Once chilled, dust with powdered sugar if desired. Cut into small squares or bars and serve as a refreshing, tangy treat.

Notes

  • Always use freshly squeezed key lime juice for the brightest flavor.
  • Softening butter to room temperature ensures an even, tender crust.
  • Chilling is essential to achieve a firm, sliceable filling.
  • Use a sharp knife dipped in warm water and dried between slices for clean cuts.
  • Adjust lime juice cautiously for more tartness to avoid preventing the filling from setting.
