Ingredients
Crust
- 1 cup butter (softened)
- 2 cups all-purpose flour
- 1/2 cup powdered sugar (confectioner's sugar)
- 1/2 teaspoon salt
Filling
- 3 cups granulated sugar
- 1/2 cup + 2 tablespoons all-purpose flour
- 8 large eggs (beaten)
- 1 1/3 cup calamansi juice (freshly squeezed)
- Powdered sugar for dusting
Instructions
- Preheat oven and prepare pan: Preheat your oven to 350°F (175°C). Lightly grease a rectangular baking pan or line it with parchment paper, leaving an overhang to easily lift the bars out later.
- Make shortbread crust: In a mixing bowl, combine softened butter, flour, powdered sugar, and salt. Use your hands to mix until just combined, forming a dough. Transfer the dough to the prepared pan and press gently into the bottom to form an even crust. Smooth the surface using the back of a spoon or the bottom of a glass.
- Prebake the crust: Bake the crust in the preheated oven for 15 to 20 minutes, or until it is firm and lightly golden. Remove from the oven and allow it to cool slightly while preparing the filling.
- Whisk together filling ingredients: In another bowl, whisk together granulated sugar and flour. Add the beaten eggs and freshly squeezed calamansi juice, and whisk until the mixture is smooth and well blended.
- Bake until just set: Pour the calamansi filling evenly over the warm crust. Return the pan to the oven and bake for 20 to 25 minutes, or until the filling is just set and slightly firm to the touch.
- Cool and dust with powdered sugar: Remove the pan from the oven and let it cool completely. Once cooled, use a fine mesh sieve to dust the top generously with powdered sugar. Slice into 8 servings and enjoy.
Notes
- Use fresh calamansi juice for the best flavor; bottled juice can alter the taste.
- Allow bars to cool completely before slicing to ensure clean cuts.
- The crust can be prepped a day in advance and refrigerated before baking.
- Adjust powdered sugar dusting according to your preferred sweetness and presentation.
