For the Shortbread:
1 1/2 sticks salted butter, room temperature
1 1/2 cups all-purpose flour
1/3 cup powdered sugar
For the Topping:
2 eggs, room temperature
1 1/4 cups granulated sugar
1/4 cup all-purpose flour
Juice of 3–4 key limes or regular limes (about 1/4 cup), strained
2 teaspoons cornstarch
1 teaspoon vanilla extract
1/4 teaspoon baking powder
1/8 teaspoon salt
1 teaspoon key lime zest
Powdered sugar and/or extra lime zest for garnish
Preheat the oven to 350°F (175°C). In a mixing bowl, combine the room-temperature butter, all-purpose flour, and powdered sugar. Mix until a crumbly dough forms.
Press the dough evenly into an 8”x8” baking dish lined with parchment paper, ensuring it covers the base and extends about 1/2” up the sides.
Bake the shortbread crust for 15-20 minutes or until lightly golden. Remove from the oven and keep it warm.
Creating the Lime Topping:
In another bowl, beat the eggs until foamy. Add the strained lime juice, cornstarch, vanilla extract, baking powder, and salt. Mix until the mixture is smooth and free of lumps.
Stir in the key lime zest to enhance the citrus aroma and flavor.
Layering and Baking:
Pour the lime filling over the warm shortbread crust, ensuring an even layer.
Return the baking dish to the oven and bake for 25-28 minutes or until the center is set and no longer jiggly.
Chilling and Garnishing:
Allow the bars to cool slightly before refrigerating them for at least 1 hour to set.
Once set, remove the bars from the refrigerator and dust the top with powdered sugar. For an extra burst of color and flavor, sprinkle additional lime zest over the powdered sugar.
Cut the chilled Key Lime Shortbread Bars into 16-25 squares, depending on your desired serving size.
Serve the bars chilled, and enjoy the delightful combination of buttery shortbread and zesty lime.
These Key Lime Shortbread Bars offer a refreshing twist on the classic lemon bar, making them a standout dessert for any occasion.
