# What You Need:
→ Shortbread Crust
01 - 1 cup unsalted butter, softened
02 - 1/2 cup granulated sugar
03 - 2 cups all-purpose flour
04 - 1/4 teaspoon fine sea salt
→ Lemon Curd Layer
05 - 1 cup granulated sugar
06 - 3 large eggs
07 - 2/3 cup freshly squeezed lemon juice
08 - 2 tablespoons lemon zest
09 - 1/4 cup all-purpose flour
→ Blueberry Topping
10 - 1 cup fresh blueberries
11 - 2 tablespoons granulated sugar (optional)
12 - Powdered sugar (optional, for dusting)
# Directions:
01 - Preheat the oven to 350°F. Line an 8x8-inch baking pan with parchment paper, allowing an overhang for easy removal.
02 - Cream the softened butter with 1/2 cup sugar until light and fluffy. Incorporate the flour and salt until just combined. Press the dough evenly into the prepared pan.
03 - Bake the crust for 18 to 20 minutes, until edges are lightly golden. Remove from oven but keep oven on.
04 - Whisk together sugar and eggs until smooth. Stir in lemon juice and zest, then whisk in flour until fully incorporated and lump-free.
05 - Pour lemon curd mixture over the warm crust. Evenly distribute blueberries on top. Sprinkle 2 tablespoons sugar over berries if extra sweetness is desired.
06 - Return the pan to the oven and bake for 18 to 20 minutes, or until the lemon curd is set yet slightly wobbly in the center.
07 - Cool completely on a wire rack. For clean slicing, refrigerate for at least 2 hours before cutting.
08 - Dust with powdered sugar if desired and cut into 16 squares for serving.
