Of all the recipes I’ve tested, lemon squares are probably the thing I’ve made the most often.
I’ve tried all sorts of recipes for lemon bars from famous pastry chefs, along with different crust/filling combinations from each to achieve the perfect square. But there was only ever one I kept coming back to, from the queen herself, Martha Stewart.

In the Martha Stewart Cookies book, she describes these bars well: “Pucker up: This version of the bake-sale favorite is the most lemony one we’ve tried. A generous crown of powdered sugar…makes them easier to stack for storage.”
What I like most about it is the unique butter grating method to create that barely cooked short-crust. It pairs well with the intense lemony filling only achieved by juicing the lemons yourself.
I will use a disclaimer when using a Martha Stewart recipe, test it before you serve it. Her empire has grown so much that her online content doesn’t match her books. Ingredients and procedure will differ between her articles and her cookbooks for the same recipe. I’ve particularly found this is the case when it comes to flour. Often there is way too much flour, so I’ve become accustomed to adding it slowly, because likely you won’t need it all.
That said, next to the lemon squares recipe in her cookies book, I have written a big “YES!” No alterations necessary, this recipe was perfection from the very beginning.
Makes one 9”x 13” pan
Crust:
- ¾ Cup unsalted frozen butter
- 1 ¾ Cups AP flour
- ¾ Cup icing sugar
- ¾ tsp salt
Butter your baking dish and line with parchment.
Grate butter on cheese grater.
Whisk flour, sugar and salt. Add butter and mix. Working quickly so the butter stays cold. (mixture will appear loose, this is normal)
Press into pan and freeze for 15 minutes.
Bake at 350°F until golden brown around edges. Approximately 25 minutes.
Filling:
- 4 Eggs
- 1 1/3 Cups granulated sugar
- 3 Tbsp flour
- ¼ tsp salt
- ¾ Cup fresh lemon juice
- ¼ Cup whole milk
Whisk sugar, flour and salt together.
Add eggs to combine.
Then add lemon juice and milk.
Strain directly over hot crust and bake at a slightly lowered temperature of 325°F until set. Approx 17 minutes.
Store in fridge.
Once cool, dust with icing sugar and cut into pieces.

Nice recipe
Those look so pretty! I looove lemon. Maybe I’ll try these for Easter!
Yes! Good Idea!
Definitely making these for Easter. What are your thoughts about putting some lemon zest in the filling? Asking for a friend. 😉
Hey Sean!
Happy to see you found my blog! I am not opposed to some zest, give it a go! …i mean, tell your friend.
lol
The short bread is in the oven. It looks so thick. I pressed the mixture in and using a 9 x 13 pan. Hope it works.
They worked!! I’m not a baker – can barely make a cookie but these worked and are delicious! Just ate my first ever lemon square. Your cook time is more accurate than martha’s Book – she only said 18 minutes and mine took closer to 27 minutes.
Fantastic! Enjoy 😊
Trying these tomorrow. Happy I don’t have to make a curd on the stove for this recipe. Fingers crossed:)
Using 2% milk or table cream though; down have homogenized milk in the house!
Good luck and let me know how it goes! 2% will work just fine.
Super-excited to try this one. I’ve never made a lemon square that truly worked.
