These easy Lemon Bars with Zested Shortbread Crust are a perfect balance of tangy and sweet. The lemon curd-like filling is creamy and smooth, tasting like sunshine in every bite. The zested shortbread crust is simply irresistible.
Preheat the oven to 350 degrees and grease a 9 x 13-inch baking pan.
Cream the butter, sugar, zest, flour, and salt. Once fully mixed, press into a 13 x 9-inch pan. Bake for 15 to 20 minutes or until firm and lightly golden. Remove from the oven.
For the filling: In a medium bowl, whisk eggs until beaten. Then add the sugar, flour, lemon zest, juice, and baking powder. Mix thoroughly and pour over the partially baked crust.
Bake for 22-24 minutes or until the edges are lightly browned and the center is set and not wobbly. Let cool completely in the pan or refrigerate for a couple of hours.
To Serve: Sift powdered sugar over the top before cutting into squares.
Notes
Storing and Making Ahead: Refrigerate these lemon squares in an airtight container for up to 5 days.
Lemons: It's best to use fresh lemon juice in this recipe. A medium-sized lemon usually yields 3-4 tablespoons of fresh juice.
