  • Make crust: An adult should grate butter on a cheese grater with large holes. In a separate large bowl, whisk together flour, confectioners' sugar, and salt. Add butter; stir with a wooden spoon until combined and mixture looks crumbly.

  • Transfer mixture to baking dish; press evenly onto bottom with your hands. Chill crust in freezer 15 minutes. Bake until slightly golden, 16 to 18 minutes.

  • Meanwhile, make filling: In a large (1 quart) liquid measuring cup, whisk together eggs, sugar, flour, and salt until smooth. Stir in lemon juice and milk.

  • An adult should remove crust from the oven and pour filling mixture over hot crust. Reduce oven temperature to 325 degrees and bake until filling is set and edges are slightly golden brown, about 18 minutes. An adult should remove dish from the oven. Let cool completely on a wire rack.

  • Grip paper; lift out dessert, and set on cutting board. With a sieve, dust with confectioners' sugar. Cut into squares.

Variations

The filling for these lemon squares is very tangy; if you want a less tart version, use 1/2 cup lemon juice and 1/2 cup milk.

Incredibly delicious and simple recipe. I had issue bringing the dough together using only the wooden spoon so I’d recommend using a dough blender; if you have one, to avoid over working the dough.

Do NOT pour the lemon filling over the hot crust or it will fall apart. Wait 2 minutes and pour carefully using the back of a spoon to make it spread as it flows. Otherwise, very yummy.

Overall I loved the recipe made it exactly as marthas, they came out perfect, they taste lemony and tarty. the thing is i can also taste them a little eggy (not much) but I can't figuer out what went wrong :(

I admit I was a little wary about the amount of lemon juice in this recipe, but I was determined to give it a try anyways. I loved the extra tartness! They are just what a lemon bar should be. Very yummy.... I will be making these again.

I have tried plenty of lemon square recipes and this one is by far my favourite. I have been making it for years! I normally add lemon zest to the crust and the filling too. It is a very strong lemon bar but a little more zest never hurts.

Don't overbake the crust or it will float when the filling is added. Add 2 T lemon zest to the filling. For a fun treat substitute lime juice and add 2T lime zest to the filling.
