For a more intense lemon flavor, increase the lemon zest and juice to your liking. Be careful not to add too much juice, or the custard may not set properly. Make sure your butter is very cold for the crust. This will help create a flaky, tender shortbread. Allow the lemon squares to cool completely before cutting. This will prevent them from crumbling and ensure a clean cut. Store leftover lemon squares in an airtight container in the refrigerator for up to 3 days.

StepPreheat oven to 350 degrees F (175 degrees C). Grease a 9x13-inch baking dish with cooking spray. (5 minutes)
02
StepIn a food processor, combine 2 cups flour, cold butter, and 1/2 cup confectioners' sugar. Pulse until the mixture resembles coarse crumbs. Press evenly into the prepared baking dish. (10 minutes)
03

04
StepIn a large bowl, whisk together granulated sugar, eggs, 1/4 cup flour, lemon juice, baking powder, and lemon zest until smooth and well combined. Pour the lemon mixture over the cooled crust. (5 minutes)
