Step 1

Preheat oven to 350°F. Line a 9x9 or an 8x8 pan with foil and spray with nonstick cooking spray.

Step 2

Make the crust by creaming the butter with a hand or a stand mixer (fitted with the paddle attachment) until smooth. Add powdered sugar, flour, and salt and mix slowly until the mixture is crumbly but sticks together when you press it between your fingers. Press the crust into the bottom of the prepared pan. Bake for about 13 minutes, or until it just starts to get a light golden brown around the edges.

Step 3

While the crust is baking, whisk the eggs until beaten. Whisk in the sugar, lemon zest, salt, and lemon juice. Pour over hot crust, then continue to bake for 15-18 minutes, or until the mixture is no longer liquid in the center and it’s lightly golden brown on top.

Step 4

Cool completely before removing from pan. Remove foil, then dust with powdered sugar. Slice and serve, dusting with more powdered sugar as desired.
