Ingredients
For the Coconut Shortbread Crust
1 ½ cups all-purpose flour
½ cup sweetened shredded coconut
½ cup unsalted butter, softened
¼ cup granulated sugar
¼ teaspoon fine sea salt
For the Lime Filling
3 large eggs, room temperature
1 cup granulated sugar
⅓ cup freshly squeezed lime juice
1 tablespoon lime zest
2 tablespoons all-purpose flour
¼ teaspoon baking powder
Pinch of salt
For the Mint Glaze
1 cup powdered sugar
1–2 tablespoons fresh lime juice
1 tablespoon very finely chopped fresh mint
1 teaspoon milk (if needed for thinning)
Instructions
-
Preheat oven to 350°F (175°C). Line a 9×9-inch baking pan with parchment paper, leaving overhang for easy removal.
-
In a mixing bowl, cream butter and sugar until light and fluffy.
-
Add flour, shredded coconut, and salt. Mix until crumbly but combined.
-
Press the crust mixture firmly and evenly into the prepared pan.
-
Bake for 15–18 minutes, or until lightly golden and fragrant.
-
While the crust bakes, whisk eggs and sugar until smooth and slightly thickened.
-
Add fresh lime juice and lime zest. Whisk until combined.
-
Sift in flour, baking powder, and salt. Mix until smooth and lump-free.
-
Pour lime filling over the hot crust.
-
Return to oven and bake for 18–22 minutes, until the center is set but slightly jiggly.
-
Cool completely at room temperature, then refrigerate for at least 2 hours.
-
For the mint glaze, whisk powdered sugar, lime juice, and chopped mint until smooth. Add milk if needed for a spreadable consistency.
-
Spread glaze evenly over chilled bars. Allow to set for 20–30 minutes before slicing.
-
Lift from pan using parchment and cut into squares with a sharp knife
Notes
For clean slices, use a sharp knife dipped in hot water and wipe clean between cuts.
Always use fresh lime juice for the best citrus flavor.
Chill completely before glazing to prevent melting.
Bars store well and taste even better the next day.
Lightly toast the shredded coconut before adding to the crust for deeper flavor.
