    Recipe Ingredients

    Unsalted butter

    All purpose flour

    Granulated sugar

    Fine sea salt

    Lemons - zest and juice

    Eggs

    Heavy Cream

    Confectioners' sugar

    step by step making the lavender shortbread crust

    Recipe Instructions

    Before beginning the recipe, preheat the oven to 350F and line an 8x8 (or 9x9) square pan with parchment paper.

    1. Combine the flour, sugar, salt and lavender in the bowl of a food processor. You can also do this by hand if you prefer.
    2. Pulse in the cold butter until large clumps form. Alternatively you can cut the butter into the dry mixture with a pastry cutter or two forks.
    3. Press the dough into the prepared pan. Use an offset spatula or the bottom of a measuring cup to smooth and even out the dough in the pan. Refrigerate for 30 minutes.
    4. Bake the crust until light golden brown. Reduce the oven temperature to 325F.
    5. In a large bowl, combine the sugar and lemon zest. Use your fingers to work the zest into the sugar. This releases the oils in the zest into the sugar and really amps up the lemon flavor. The mixture should be damp and very fragrant.
    6. Whisk in the flour and salt.

    1. Whisk in the eggs.
    2. Whisk in the lemon juice and cream.
    3. Pour the lemon mixture over the warm crust.
    4. Bake for 25-30 minutes until the mixture is just set and the filling jiggles just slightly.
    5. Let the bars cool for an hour at room temperature before transferring to the refrigerator to cool for an additional hour. While I have to admit that many times I’ve dug into these lavender bars with a fork while still hot because they are THAT good, they are best served cut into squares or wedges chilled or room temperature and finished with a dusting of confectioner’s sugar.

    Baking Tips

    • Use fresh lemon juice only. Bottled juices or concentrates can have preservatives and additives that change the flavor and would be noticeable in these bars.
    • Don't over bake. You want the filling to remain more of a set custard and not overly solid. Over baking can cause the filling to be rubbery.
    • These bars are the easiest to slice when they are cold. At the very least, they should be completely cool before cutting into them. Use a sharp, not serrated knife to slice into the bars downwards, then carefully pull the knife up. Wipe the knife off on a damp towel between slices for the neatest cuts.
    • The crust can be warm but not hot when pouring over the lemon filling. Lukewarm is best, as a hot crust can absorb the lemon filling, creating a soggy crust.

    Storage and Freezing

    Store any leftover lemon bars in the refrigerator in an airtight container for up to 5 days.

    These bars (without confectioners' sugar on top) can also be frozen for up to 3 months. After chilling the bars, cut into individual bars and place on a baking sheet. Freeze for one hour, then wrap each one with plastic wrap and place in a zip top freezer bag. Defrost the bars in the refrigerator and dust with confectioners' sugar before serving.

    Recipe FAQs

    Why do my bars have a crust on top after baking?

    Oftentimes lemon bars will have a thin, bubbly crust on top. This is due to air from the eggs rising to the surface creating air bubbles, and is completely normal.

    After dusting the bars with confectioners' sugar, the bubbles won't be noticeable.

    How do I know when the bars are done cooking?

    The edges of the bars will start to turn light golden brown while the center looks just set and no longer jiggles.

    My bars turned out gooey and soggy. What went wrong?

    Be sure that the crust has been fully baked before adding the lemon filling. Otherwise the crust can absorb the filling, creating a soggy mess.

    Undercooking can also cause the bars to be gooey and soggy.

    What kind of pan do I need to make lemon bars?

    Either and 8x8 or 9x9 pan will work. Glass pans are preferable as they cook the crust better and prevent the bars from having a metallic taste. Metal pans are fine (I used one in the process photos above, just be sure to line the pan with parchment paper first.

    Equipment

    • Food processor
    • 8x8 square pan

    Ingredients
     

    Shortbread Crust

    • 1 ¼ cups all purpose-flour
    • ¼ cup granulated sugar
    • ¼ teaspoon fine sea salt
    • ½ teaspoon culinary lavender
    • ½ cup unsalted butter, cut into cubes, cold

    Lemon Curd Filling

    • 1 ⅓ cup granulated sugar
    • 1 tablespoon lemon zest
    • 3 tablespoon all purpose flour
    • pinch of fine sea salt
    • 4 large eggs
    • ⅔ cup lemon juice, freshly squeezed
    • ⅓ cup heavy cream
    • confectioners sugar for dusting

    Instructions
     

    For the Shortbread Crust:

    • Preheat oven to 350 degrees F. Line a 8x8 square pan with two sheets of parchment paper, making sure the parchment extends over the sides of the pan to form a "sling". Secure the sides with binder clips if you would like.
    • In a food processor, pulse together the flour, sugar, salt and lavender until well blended. You want the lavender to be dispersed and chopped up a bit.
      1 ¼ cups all purpose-flour, ¼ cup granulated sugar, ¼ teaspoon fine sea salt, ½ teaspoon culinary lavender
    • Add in the cubes of butter and pulse until the mixture is sandy and starts to form clumps.
      ½ cup unsalted butter, cut into cubes, cold
    • Gently press shortbread mixture into an even layer over the bottom of the prepared pan. Refrigerate for a minimum 30 minutes.
    • Bake crust for 25-30 minutes or until the crust starts to turn a golden brown.
    • Remove shortbread from the oven, let it cool slightly and reduce the temperature to 325 degrees F.

    For the lemon filling:

    • In a medium bowl, blend together the sugar and lemon zest with your fingers to release the oils from the zest. The mixture should be damp and very fragrant.
      1 ⅓ cup granulated sugar, 1 tablespoon lemon zest
    • Whisk in the flour and salt until blended.
      3 tablespoon all purpose flour, pinch of fine sea salt
    • Add the eggs and whisk briskly so that the sugar doesn't "cook" the eggs and form clumps.
      4 large eggs
    • Add the lemon juice and cream and whisk to fully incorporate.
      ⅔ cup lemon juice, freshly squeezed, ⅓ cup heavy cream
    • Pour the filling over the warm shortbread and bake for an additional 25-30 minutes, until filling looks set and doesn't jiggle.
    • Let the bars cool to room temperature, about 1 hour. Place in the refrigerator to cool for an additional hour. The longer they cool, the easier and prettier they are to slice.
    • Transfer bars to a cutting board and cut into squares or wedges. Using a sieve, sprinkle with confectioner's sugar and serve.

      This was an amazing recipe - I made without lavender for Atlanta (Southern) elderly clients as well as my family and everyone adored them!

      These were the best lemon bars I've made. I used one less egg and added lavender to the filling - delicious!
