Ingredients

Scale

Crust

  • 1 cup unsalted butter, softened
  • 2 cups all-purpose flour
  • ½ cup powdered sugar
  • ½ teaspoon vanilla extract

Filling

  • 2 cups sugar
  • 1 teaspoon dried culinary lavender
  • 4 large eggs
  • 6 tablespoons freshly squeezed lemon juice
  • 4 tablespoons flour
  • 2 tablespoons freshly grated lemon zest
  • 1 teaspoon vanilla extract
  • ¼ teaspoon lavender extract
  • ½ teaspoon salt

Instructions

  1. Preheat Oven: Preheat your oven to 350 degrees F (175 degrees C) to prepare for baking the crust and filling.
  2. Prepare and Bake Crust: In the bowl of your electric mixer, beat together softened butter, all-purpose flour, powdered sugar, and vanilla extract until the mixture becomes crumbly. Press this crumbly crust evenly into the bottom of a 9×13 inch baking dish. Bake it for 20 minutes until it is slightly set and firm enough to hold the filling.
  3. Flavor Sugar with Lavender: While the crust is baking, combine the sugar and dried culinary lavender in a bowl. Whisk them together thoroughly to infuse the sugar with floral notes. This step can be done a few days ahead to deepen the lavender flavor.
  4. Mix Filling: In the mixer bowl, beat the eggs and freshly squeezed lemon juice until blended. Gradually add the lavender-infused sugar, flour, lemon zest, vanilla extract, lavender extract, and salt. Continue beating until the filling is fully combined and smooth.
  5. Assemble and Bake Filling: Pour the lavender lemon filling mixture evenly over the pre-baked crust layer in the baking dish. Bake for an additional 25 to 30 minutes until the top is slightly cracked and set but the inside remains somewhat soft and curd-like.
  6. Cool and Serve: Remove from the oven and lightly sprinkle the top with powdered sugar. Allow the bars to cool completely before slicing. These bars are delicious chilled from the fridge, which firms up the texture, but may also be served at room temperature if preferred.

Notes

  • If you prefer not to use dried culinary lavender flowers, increase the lavender extract in the filling to ½ teaspoon for strong floral flavor.
  • Alternatively, if you skip the lavender extract, increase dried lavender to 1½ teaspoons total and let the lavender sugar mixture sit for 1-2 days to enhance flavor.
  • Storing the bars in the refrigerator makes slicing easier and keeps them fresh longer.
  • Ensure to use culinary-grade dried lavender to avoid bitterness or unpleasant flavors.
