With their crisp, buttery crust and creamy lemon filling, these little squares taste of spring. Have some with a glass of milk or a cup of tea.

  • Make the crust: In a food processor, pulse flour with confectioners' sugar, cornstarch, and salt. Add butter; pulse until mixture resembles coarse crumbs. Press into bottom and 3/4 inch up sides of prepared pan. Refrigerate 15 minutes.

  • Bake until crust is lightly browned 20 minutes. Let cool slightly in pan. Reduce oven heat to 325 degrees.

  • Meanwhile, make the lemon filling: In a bowl, beat eggs with an electric mixer until thick. Beat in granulated sugar, lemon juice, flour, baking powder, and salt. Pour over warm crust. Bake until set, about 20 minutes. Cool to room temperature; refrigerate about 1 hour.

  • Using paper overhang as an aid, lift square from pan. Sift remaining tablespoon confectioners' sugar over the top. Cut into 16 squares.

Cook's Notes

If you don't have a food processor, you can make the crust by mixing together the dry ingredients in a large bowl, and then rubbing in the butter with your fingers.

Followed the directions exactly but had the same problem as another reviewer. The lemon filling went under the crust during baking. Have made other lemon bar recipes without this problem. Will not make this again.

I made the lemon squares yesterday for our weekly family dinner. One of my family members celebrated her birthday yesterday, and she loves lemon pie. The squares were delicious and easy to make, but the 1/2 t salt printed in the recipe was a little too much. According to Sarah's video recipe, she used 1/4 t salt. Also, the next time I make them (later this week) I will bake the crust a little longer for a crunchier base and add the zest of a lemon to the filling for a stronger lemon flavor.

the baking time is affected by the size pan. Compare the two pictures. One bar is taller than the other, since it was baked in a smaller pan. The flatter square was baked in a larger pan and would have baked more quickly. I suggest cutting them smaller so when you crave another, like NOW, there might be one left.

The lemon squares were delicious and easy to make. They took much longer to bake (almost 15 minutes more) because the center was still very liquid so I just kept watch until they were finished, which was easy because the baked areas were very distinctive visually . Everyone enjoyed them so I'll be making them again! And yes, the cornstarch goes in the crust mixture, just like many cookie recipes.

There is no typo in the recipe. Do follow it as written. The corn starch does, indeed, go in the crust, and the filling will absolutely set just the way it should if you follow the recipe as it is written. Corn starch is often used in many crust recipes. This is not uncommon. This is, without a doubt, the best lemon squares recipe. I have tried many (far too many) and found several others that were ok, but this one blows them all away. The crust is perfect, the filling is heavenly. To die for!

I have made these time and time again ,love them the lady who said there was a typo on the cornstarch -recipe is correct cornstarch in the crust makes for a tender crust that's why it is used in shortbread cookies , they come out perfect for me , as for being gooey make sure you're adding your flour to your filling and do sift it into the wet so it does not clump up

ATTENTION ALL! THERE IS A TYPO IN THE RECIPE! THE CORNSTARCH SHOULD NOT GO IN THE CRUST, IT SHOULD GO IN THE FILLING!! IF YOU PUT THE CORNSTARCH IN THE CRUST INSTEAD OF THE FILLING IT MAKES THE FILLING FAR TOO LIQUID-Y.

The flavor of these lemon squares was on par with what I had in mind, however, the consistency was a bit less set than other recipes and left the squares a bit extra "gooey." Maybe I'm just too picky, though.

These are in the oven right now. The recipe is very similar, if not the same to one I used to make years ago. I think this one calls for more lemon juice than the old one and I added the zest of a lemon because I like lots of flavor. I didn't have any parchment so greased the pan instead. I'm taking them to a luncheon tomorrow and as long as I don't burn them, I think they'll be a hit.

Delicious!! The lemon flavor is perfect - tart and not too sweet. The crust is also excellent. I will make these again and again!

Never made lemon squares before, but these were great! They were easy to make and were very good! I will be making these again.

These were unfortunately the worst lemon squares I have ever made. I left them in the oven for five more minutes and they really never set ... they were gooey, too tart, and just kind of gross.

Used this recipe for my first time baking lemon bars for a family get-together and got several complements on them! These bars taste so much better and fresher than store-bought ones, and are easy to make. I will definitely be using this recipe again!

This is a favorite, and a great desert in a pinch pretty much any meal. We sold them in the bakery by the tray full. My favorite treat as a child and still carrying 40 pounds from eating them.

We LOVE this recipe. Second time I made it for a dinner party I thought I ruined it because after chilling the crust I forgot to bake first and then add fillilng. I chilled and filled and stuck in the oven then realized my mistake. Unsure what to do but decided to go with the flow. Left in the oven for about 35 minutes at 350. Looked okay when I pulled out of oven. Served a few hours later to guests and no one, including me, would have guessed the boo-boo I had made. Still really yummy.

I first made these squares about a year ago, and they were a hit with my family. Since then they've been made for potlucks at work and whenever we were in the mood for a lemony treat. My wife loves them, and I enjoy making them for her.

I just made this recipe and they turned out beautifully! I added a little lemon zest to the juice because I like lemon desserts with a lot of zing, but otherwise I followed the recipe verbatim. Sorry some had trouble, but I would recommend it.

kristina, i made lemon bars with a very similar recipe today and got the same weird inverted crust over filling. this was, however, due to my intentional undermixing the filling. the first two times i made it i really whipped up the eggs until they doubled in volumn. the result was too fluffy and flakey and got messy when i tried to cut it. today i just gently stirred the eggs with rest of ingredients without whipping them, to try and get a creamier topping. so that's what went wrong here...

I did not like this recipe... after baking and following directions exactly, the crust melted away and seemed to end up on top. The middle was too gooey, and way to tart. I tried it a second time just in case i did something wrong... and same thing. I would not recommend this recipe!
