These bars captured spring in every bite! Buttery shortbread base with bright lemon curd and delicate lavender - floral without being overpowering.
Preheat the oven to 350°F (175°C). Line an 8x8-inch baking pan with parchment, leaving an overhang for easy removal.
In a large bowl, cream together 1 cup unsalted butter and 0.5 cup powdered sugar until light and fluffy. Add 1.5 cups all-purpose flour, 0.5 tsp salt, and 1 tsp vanilla extract. Mix until a crumbly dough just comes together.
Press the dough evenly into the bottom of the prepared pan. Bake for 18–20 minutes, until the edges are pale golden. Let cool slightly while you prepare the filling.
For the lemon lavender curd, lightly whisk 3 eggs in a medium bowl. Add 1 cup granulated sugar, 1/3 cup fresh lemon juice, 1 tbsp lemon zest, and 1.5 tsp dried culinary lavender (rub between your fingers to release flavor). Whisk until smooth.
Pour the lemon lavender filling over the warm shortbread base. Return to oven and bake another 22–25 minutes, until just set and lightly golden at the edges.
Cool completely in the pan, then refrigerate for at least 1 hour to firm up. Dust generously with 2 tbsp powdered sugar before cutting into bars.
Tradition tip: In springtime, lavender and lemon symbolize renewal—these bars are perfect for a seasonal dessert platter or Mother’s Day tea.
