These bright bars are the perfect afternoon pick-me-up.
For the crust:
1 cup butter, softened
½ cup powdered sugar
¼ teaspoon kosher salt
2 cups all-purpose flour
For the filling:
1½ cups sugar
¾ cup Meyer lemon juice (from about 4-5 lemons)
2 tablespoons Meyer lemon zest (from about 4-5 lemons)
Pinch kosher salt
½ teaspoon baking powder
¼ cup all-purpose flour
1. Liberally grease a 9×13 inch baking pan with a little bit of the softened butter. Preheat the oven to 350°.
2. To prepare the crust: In a large mixing bowl or stand mixer, mix the softened butter, powdered sugar and kosher salt on high until well combined. Add the flour and mix on low speed until dough begins to just stick together and clump up. Press the dough mixture evenly into the bottom of the prepared baking pan with your hands. Bake for 20-25 minutes, or until just starting to brown.
3. Meanwhile, make the topping: In the same mixing bowl, mix together the 5 eggs, sugar, lemon juice, lemon zest, a pinch of kosher salt and baking powder on medium-high speed until well combined and pale in color. Add the flour and mix until smooth.
4. After the crust has baked, remove from the oven and turn the temperature down to 325°. After the crust has cooled in the pan slightly, pour the topping in and bake 15-20 minutes, or until set. Remove from the oven and allow to cool in the pan for at least 20 minutes. Cut into squares and top with powdered sugar, berries, lemon zest, and/or mint leaves, if desired.
