These lemon squares with a shortbread crust are a sweet, tart, delicious treat, made with seven easy ingredients. The lemon filling is smooth and thick and sits on a flaky, buttery shortbread crust.
In a food processor pulse flour, icing sugar, cold butter (cubed), and vanilla until the mixture has a crumbly, cookie-like texture. Alternatively, use a mixing bowl, pastry cutter, and your hands to form the same crumbly texture.
Press the shortbread mixture firmly into a 8'' x 8'' baking dish.
Bake at 350 for 20 minutes, or until the edges begin to turn golden.
While the shortcrust is baking, combine the sugar, beaten eggs, lemon zest, lemon juice, and flour. Whisk until smooth and well-combined.
Pour over hot shortbread.
Return to the oven and bake for 350 for 25-30 minutes. Until the center no longer jiggles.
Let cool completely, before refrigerating or serving.
Before serving, dust with icing sugar.
