Meyer Lemon Lavender Bars

• 8 ounce unsalted butter, softened
• 1/2 cup lavender sugar
• 2 cup flour
• 1/2 teaspoon kosher salt

• 6 large eggs at room temperature
• 1 cup meyer lemon juice
• zest from two meyer lemons
• 1/2 teaspoon lemon oil (optional)

1. To make the crust, in the bowl of a stand mixer, cream the butter and lavender sugar on medium speed until light and fluffy, about two to three minutes.
2. Add the flour and salt and mix until the dough begins to come together.
3. Transfer the dough to a 9x13 baking dish and using your fingertips, press the dough into an even layer that covers the entire pan.
4. Chill the dough for at least thirty minutes.
5. Meanwhile, preheat the oven to 350 F.
6. Bake the chilled crust for twenty minutes.
7. While the crust is baking, prepare the filling.
8. Whisk together the granulated sugar, eggs, lemon juice, lemon zest and lemon oil, if using, until combined.
9. Whisk in the flour until the mixture is smooth.
10. After twenty minutes, remove the crust from the oven and turn the heat down to 325 F.
11. Pour the filling over the crust and return the pan to the oven and bake until the filling is set, 30-35 minutes.
12. Dust the top of the lemon bars with confectioner's sugar while they are still warm.
13. Cool on a wire rack before cutting.
