ingredients for lavender lemon bars:

For the honey lemon custard:

  • 4 large egg yolks
  • 1 can (14 oz) sweet condensed milk
  • 3/4 cup fresh lemon juice (juice from 3 lemons)
  • 2 tablespoons of local raw honey, I used my favorite flower infused honey

For the lavender shortbread cookie crust:

  • 1/2 cup (100 grams) sugar
  • 2 cups (250 grams) all-purpose flour
  • 1/2 teaspoon salt
  • 1 cup (227 grams or 2 sticks) unsalted butter room temperature
  • 1 teaspoon vanilla extract
  • 1/2 tablespoon culinary grade dried lavender buds
  • juice + zest from one lemon

How to make lavender lemon bars:

Preheat your oven to 350 degrees F or 176 C and line a square baking sheet tin with parchment paper, leaving enough paper on the sides so that you can easily lift the tart after it’s baked and cooled. I used an 8×8 baking pan.

Shortbread Base:

  • In a mortar and pestle or food processor, combine the dried lavender, lemon zest, and sugar. Grind or process until the mixture becomes a finely textured lavender sugar.
  • In a stand mixer or a large mixing bowl, add the lavender sugar, additional lemon zest, lemon juice, butter, and salt. Mix for about five minutes, or until the butter becomes a deeper yellow color—this is a good sign that everything is well creamed together.
  • Next, add the vanilla and flour. Stir until fully combined, then use your hands to bring the mixture together into a dough.
  • Press the dough evenly into a parchment-lined baking pan. Use a fork to poke holes across the surface—this helps prevent the butter from bubbling while baking.
  • Place the pan in a preheated oven and bake for 20 minutes. The cookie will still be soft and fluffy when it comes out of the oven, but it will firm up as it cools.
  • While it’s baking, you can prepare your honey lemon custard.

Lemon honey custard:

  • In a large bowl, whisk together yolks, condensed milk, honey, and lemon juice until smooth. Pour over hot crust in pan; return to oven, and bake until filling is set, 25 to 30 minutes. Cool completely in the pan.
  • Move to refrigerator and let bars set.

notes:

You’ll have to allow this custard to sit in the fridge and set for at least an hour before digging in. They’re worth the wait.

Then cut and enjoy!
