INGREDIENTS
For the Shortbread Base:
- 1 cup (2 sticks) softened unsalted butter
- 1/2 cup powdered sugar
- 2 cups all-purpose flour
- 1/4 teaspoon salt
- lime zest
For the Key Lime Filling:
- 1 cup powdered sugar
- 4 large eggs
- 2/3 cup fresh lime juice (you can also use regular lime juice )
- 2 tablespoons 00 flour
- 1/2 teaspoon baking powder
- powdered sugar for dusting (optional)
- lime slices for decoration (optional) )
INSTRUCTIONS
1. Preheat the Oven:
Preheat the oven to 175°C (350°F). Grease a square tin (23 x 23 cm) with butter and line with baking paper, leaving an overhang on both sides to make it easier to unmold.
2. Make the Shortbread Base:
In a bowl, beat the softened butter with the granulated sugar until the mixture is light and fluffy.
Add flour, salt and lime zest. Mix until a homogeneous mixture is obtained.
Press the shortcrust pastry mixture evenly onto the bottom of the prepared tin.
Bake the shortcrust pastry in the preheated oven for about 15-20 minutes or until the edges are lightly golden brown. Remove from the oven and let cool slightly.
3. Prepare the Key Lime Filling:
In another bowl, mix together granulated sugar, eggs, lime juice, all-purpose flour and baking powder until well combined.
Pour the lime filling onto the finished shortcrust pastry base.
4. Bake the Bars:
Return the pan to the oven and bake for another 20 to 25 minutes, or until the edges are firm and the center jiggles slightly.
5. Cool and Serve:
Let the Key Lime Shortbread Bars cool in the pan on a wire rack.
Once cooled, refrigerate bars for at least 2 hours or until completely cold. This makes them easier to cut.
6. Slice and Garnish:
Use the excess piece of baking paper to remove the bars from the mold. Arrange them on a cutting board.
Cut the bars into squares or rectangles. Sprinkle with powdered sugar if desired.
For an extra hint of citrus flavor, garnish with thin lime slices (optional).
7. Enjoy:
Serve fresh Key Lime Shortbread Bars and enjoy the delicious combination of sweet shortbread cookies and tangy Key Lime sauce.
