Easy Lemon Squares, these tangy squares are quick, easy and so delicious, made with a buttery shortbread base and a fresh lemon filling. Easy and tasty bars. They are a definite must bake this Holiday Season!
This recipe for Lemon Squares was given to me by my amazing cousin, who I can’t wait to see again (soon!!) and I think they would be great to make for all the lemon-loving dessert people out there.
My mother loved baking with lemons, from Lemon Bread to Lemon Cake it seems we can never get enough. In Italy there is a never-ending abundance of lemons, everyone has a lemon tree or two or three.
Funny thing is, my husband and I plant and plant lemon trees and the trees look beautiful, but no lemons. Very strange. But that doesn’t keep us from trying.
When we first arrived in Italy, one week after our wedding, we lived in a beautiful house that belonged to my brother-in-law. And we planted, yup you guessed it, our first lemon tree, and of course we never saw not even one lemon.
Eight years later we moved into our own home, and that lovely lemon tree started to produce and I mean produce tons of lemons! Lucky for them!
So here we are, 9 years later with a few nice green trees and unfortunately still no lemons. Maybe it is time to think about moving again… Thank goodness everyone we know has lemon producing trees.

How to make Lemon Squares

Pat evenly onto the bottom of the prepared baking pan.
Bake for about 20 minutes, remove from the oven.

Cut when the bars are completely cooled.
How to know when Lemon Bars are done
You know when Lemon Bars are done when you gently shake the pan and the filling is set and no longer jiggles. Be sure to let the squares completely cool before cutting. They need to set up, so don’t rush this step.
I like to let them cool at room temperature for about an hour then refrigerate for about 1-2 hours before cutting.
Tips for making the Best Lemon Bars
- Be sure to use fresh lemons, you want the best tasting bars since it’s all about the lemons!
- For easier removal line your baking pan with parchment paper.
- Be sure to bake the crust before adding the filling.
- You may want to refrigerate them before cutting, it makes it easier to cut into clean even squares.
- Dust with powdered sugar before serving.
FAQs
They should be stored in an airtight container in the fridge, although they can be left out for a few hours while they are being served. They will last up to 4 days in the fridge.
Lemon Squares can also be frozen, place the completely cooled cookies, on a cookie sheet, freeze for 1 hour then transfer to a freezer safe container, place parchment paper between the layers, they will keep for up to 3-4 months in the freezer. Be sure to thaw the frozen cookies in the fridge before serving. If you do freeze them, don’t dust with powdered sugar, that can be added before serving.
If they are too runny or jiggle too much, it’s because they have not been baked for enough time. Be sure to bake the bottom crust for the time stated that will help too.
These Lemon Bars are perfect as a dessert or even an afternoon snack, amazing with a cup of tea or serve to family or guests. Enjoy!

Tami says
These were delicious!! Would I just double everything if I want to make a batch in a 9 X 13 pan?
Rosemary says
Hi Tami, thanks so much, yes that would work. Happy New Year!
Olivia says
Tried this recipe and the filling seemed to seep into the crust? Are you supposed to let the crust cool before you pour the filling in/on to then bake? Thank you!
Rosemary says
Hi Olivia, the base is pre-baked for 20 minutes, so it really shouldn’t seep into it. The recipe does instruct to pour on the warm base, so it should cool down a bit straight from the oven. Hope that helps. Let me know. Take care!
Christine says
I’m wondering where this recipe actually came from because it is the same as the recipe passed down to me from my Grandma.

Hi dear Rosemary ,
Hope you are doing well and in great health and thank you so much for sharing this lemon bar recipe . I really enjoyed it a lot, especially the shortbread is really delicious, crispy and perfect . My mom doesn’t eat all kinds of sweets and desserts, but she liked this very much . I will be making double this recipe from now on . Many thanks .
Rosemary says
Hi Nooshin, thanks so much so glad you and your Mom enjoyed the bars. I hope you are well also! Take care.
Nooshin says
Thanks for your answer , but my sister asks if she can use marmalade instead of lemon filling. Thank you for letting me know.
Rosemary says
Hi Nooshin, I don’t know how that would work. The marmalade would probably burn if you baked it with the crust, so i guess you could spread it on after you baked the base. 🙂
