Cooking Notes

Becky Peterson

Needs more lemon juice. This is one of my all-time favorite cookie recipes (I am a sweet-tart addict.) I was checking several copies of the recipe I have and found they are basically, through all time, the same..only varying in whether to include lemon zest in the curd or not. THIS recipe calls for 1/3 C lemon juice. All others suggest 2/3 C and I believe this is the best amount of juice to use. You can halve this recipe and use a 8" square pan.

Mackenzie

My go-to lemon bar recipe for 16 years. I usually add more lemon juice (2/3 cup total) and add the zest from all the lemons as well.

Oscar madison

I didn’t have any lemons on hand but substituted the canned pinto beans on my shelf. Tabasco for the confectioners sugar and a last minute swap of flour tortilla for the shortbread. Turns out as a lemon square it was awful, but I made a pretty decent burrito.

Tessa

Confectioner's sugar is important to make the shortbread crumbly. My recipe includes the zest from the lemons, too, and I probably put 5-6 lemons, zest and juice, into each 9x13 pan.

Line the pan with foil to make it easier to lift out the lemon bars.

You can use other fruits

I didn't have any lemons on hand, but cherries are in season and I had an extra lime; turns out cherry lime bars are very good. Run 12-20 cherries and juice from 1-2 limes through a food processor and substitute for the lemon juice.

Try lining the pan with parchment paper--they come right off!

Susan

Why do people make so many changes to the recipe ? I can understand one or two adaptations, but some use limes, cherries, etc. & that completely changes the recipe. I always say, the first time follow the recipe & after that changes are ok.

Félix Fernández de Castro

I baked the recipe just yesterday and:Added almost three times the quantity of lemon juice (lime juice is also an excellent option, in fact).Used half (yes, HALF of the quantity of sugar, both confectioners and granulated), which was sweet enough and definitely lighter.And baked it at 250ºC instead of 350ºC for 15 min instead of 25 for the dough and then an extra 15 min for the whole cake.And the result was still amazing.

Sophie

Used Myer lemons (after using all the zest for Limoncello!) and added the ground seeds of about 6 or 7 Cardamom pods to the shortbread. Also a little sea salt along with the powdered sugar on top. Definitely recommended, adds a subtlety and depth of flavor that sometimes lemon squares lack. And they pop out of the pan fine!

I'd like to hear from both sides, the people who measure with a cup and the folks who use a scale. Guaranteed that the two groups are using different quantities of flour and that would seem to be important. One cup of flour, per King Arthur, the flour people, weighs 120 grams. Your recipe shows 128 grams (x 2 = 256). Using weights is supposed to lend more accuracy to recipes but it seems that darn near every recipe writer has different numbers for their flour. Responses??

Jackie

The only thing difficult about these delicious cookies is getting them out of the pan. I recommend lining the pan with foil as the lemon filling sticks to the sides of the pan and makes it hard to get them out

Olivia

My best friend and I used to make "Lucy's Lemon Squares" from The Peanuts Cook Book (1969). Simple, foolproof recipe, even for a pair of eleven-year-olds. Look it up if you're having trouble with this!

Betsy Karpenkopf

I have made a number of versions of lemon squares over the years, but hadn’t baked any for quite a while. All of the recipes are pretty similar. I did not like the one with olive oil in the lemon filling. Here I was hesitant about the use of melted butter in the shortbread base. The squares turned out very tasty. I may give this recipe another try and use softened, not melted butter, and then decide which version I prefer. I must admit that this batch has been disappearing rather rapidly...

Hannah

This was easy and tasty. However, next time I would use a bit less of the dough base to get a thinner crust and better crust-to-lemon ratio.

Allyson Smith

I have been making lemon bars for a long time, and just compared this recipe to my own. Mine has only 1/4 cup of lemon juice and a tablespoon of lemon peel, otherwise just the same, and I must say, they are fantastic. So I would not hesitate to follow this recipe to a "T"; I might still add some peel, though admittedly, the texture is probably smoother without it. If you prefer a more lemony taste, you can add either a little lemon oil 1/4 - 1/2 tsp. (I like Boyajian) or lemon zest.

Eliza

This is a PERFECT, EASY lemon bar recipe with two tweaks:-2/3 cup lemon juice instead of 1/3 as written (takes about 4-6 lemons in my experience)-Second bake for 12-15 minutes, not 20-25 as written. Take it out AS SOON as it stops waving when you shake it. There should still be a slight wobble in the middle. Otherwise it will be over baked. It will set as it cools.Voila, perfect lemon bars that disappear at parties.

Glynn

My first NYT recipe! Once I’d figured out what confectioners sugar is in the UK went pretty well but Would use a lot more lemon next time - wish I’d read other folks comments before cooking this one, also suggest doing second bake a little cooler - 170C max as it was a little brown by the time the eggs were done.

geteb

These are super fast, easy & delicious. Added another 1/3C lemon juice & reduced the sugar in the lemon topping by 1/2C. Absolutely scrumptious and the shortbread crust is to die for. SO buttery & crisp. Just like a Danish pastry (I'm 1/2 Danish....all butter, minimal sugar ;-)

Fran

Make ahead friendly?

Perri C

i agree with needing more lemon. Mine came out more custard then lemon. yummy but not what I expected. will definitely try again with more as suggested.

Jessica Hunting

These are so delicious and easy to make! Agree with the other comments that adding 1/2cup or more of lemon juice was necessary. The shortbread bottom is so tasty and the perfect pairing with the lemon. These were devoured up by family and friends and will become a staple at baking time!Tip: Roll out the shortbread bottom before placing into the baking pan. It made it a lot easier to mold into the pan and created an even bottom.

Penni

Very rich and delicious Next time less butter and sugarUse parchment paper Used 3 lemons and zest

abby

Awful recipe. Do not use.

geteb

The reason being? (I found this recipe to be superb adding some more lemon juice & reducing the sugar in the topping by 1/2C)

K EB

I followed this recipe exactly and found the crust to be too crumbly to hold together...seems to me there's too much butter in it. Next time I'll use less, and a bit more lemon, as others have suggested. These are deliscious, just fall apart when you pick them up.

Ali

Excellent and easy! Put parchment paper underneath crust so it was easy to extract from pan. Used double the lemon juice (2/3 cup) from 2.5 lemons, would recommend even a bit more. Baked 25 minutes for curd but should’ve done less so edges didn’t brown.

Vicki

I made the recipe with no modifications--delicious and very lemony. It tastes great frozen as well. Recipe says 16 bars but they are so rich, most people eat half a bar. Actually I cut them into squares. Parchment paper helpful but cutting is a bit messy. Another shake of confectioner's sugar can cover any rough edges.

Martha J.

Went with the consensus: 2/3 c. lemon juice and added zest of 2 lemons to the batter. Everyone loved it!

Jo

Don’t forget the parchment paper

linda

Used lemon zest in batterUsed lemon juice over1/3. Two large lemons. Sprinkled lime zest over batter before bakingSprinkled lime zest with powdered sugar

Eve

I added some lemon zest and ground up lavender to the sugar in the second step and it as even better. I agree with the other commenters that it isn’t quite tart enough so I added a few extra tablespoons of lemon juice as well the second time. Highly recommend adding lavender.

FAQs

What is the best way to cut lemon squares? ›

To cut, use the foil overhang to lift the baked square out of pan and onto a cutting board. Carefully loosen the foil from the edges of the crust, using a knife if necessary. Using a sharp knife, cut into squares or triangles. Use a fine sieve to dust the squares with Confectioners' sugar.

Why are my lemon squares runny? ›

Runny lemon bars - This is a common issue for people who are making lemon bars for the first time. Usually, it just means that you need to bake your bars longer. If your bars seem to brown at the edges, you can cover them with aluminum foil and turn down the heat.

Why did my lemon bars get brown on top? ›

Remove your lemon bars from the oven before they turn brown on top. Browning means they're over-cooked, and the custard mixture can curdle.

Do you have to refrigerate lemon bars? ›

Lemon bars should be stored in an airtight container and refrigerated in order to prevent bacterial growth or foodborne illness. The filling in lemon bars is made with eggs and can become a breeding ground for bacteria if it's kept in the danger zone (between 41 and 153 degrees F).

How do you cut lemon bars without making a mess? ›

I have found that a hot, wet, very sharp knife helps quite a bit. Also, make sure the bars are completely chilled before cutting.

Why do my lemon bars taste eggy? ›

If your lemon bars have a strong eggy taste/smell, it's likely due to the lemon curd being overbaked. Be sure to take the lemon bars out of the oven as soon as they're done. Your oven may also be running a little hot.

Why did my lemon bars curdle? ›

If they used much more lemon juice, they'd: have to bake their bars for a long time to set them up, end up with a soggy crust, and. probably have curdled edges, where the hot pan would overcook the edges while waiting for the center to firm up.

Why is my lemon filling not thickening? ›

Lemon Curd needs to be cooked over medium-low heat for about 5-10 minutes until the curd reaches 170 degrees F in order for it to thicken. The culprit might also have to do with ingredients such as not having the correct eggs to lemon juice ratio (not enough eggs), not having enough butter or the butter not being cold.

Why did my lemon bars crack? ›

Don't Over-Bake.

If you leave them in the oven too long, it can cause your bars to crack. The surface of your lemon bars should have small bubble holes, but not large cracks.

Why is there a crust on top of my lemon bars? ›

The crust forms when the sugar in the lemon bar mixture caramelizes and browns during baking, creating a slightly firm, crispy layer over the bars. The top crust isn't always visible, as we all enjoy sprinkling powdered sugar on top of the bars before serving.

Can you rebake undercooked lemon bars? ›

Undercooked lemon bars can be rebaked by placing them back in the oven for about five minutes. Be sure to watch them closely, as they can quickly become overcooked. If you are using a lemon bar recipe that doesn't call for olive oil, you can try substituting it with olive oil to give your lemon bars a boost of flavor.

What is the brown dot on my lemon? ›

Brown spots vary in appearance and can indicate a range of problems. Uniform spots with clear boundaries often point to fungal issues, while irregular blotches could signal bacterial infections. Spots with a yellow halo might be citrus canker, and those that look like tiny scabs could be a sign of lemon scab disease.

Is it OK to freeze lemon bars? ›

Lemon bars can be kept at room temperature for a few hours but should be refrigerated after that. Refrigerate up to a week or freeze for 3-4 months (see make-ahead instructions below).

Why lemon should not be refrigerated? ›

In fact, lemons will last up to four to six weeks in the fridge. You can safely store lemons at room temperature, but like any fruit, they will start to go bad quicker. On average, you have about a week to use lemons stored at room temperature before they start to dry out, go soft, or worse, begin to mold.

Why do my lemon bars have bubbles? ›

AIR BUBBLES ON TOP OF BAKED LEMON BARS: The air bubbles on top of the baked lemon bars are completely normal. It's the air from the mixture rising to the surface. They come from the air of the beaten eggs. They rise to the surface when the eggs cook in the filling.

How do you cut lemons into shapes? ›

For wedges, cut about 0.5-1 in (1-2.5 cm) from each end. Then, stand the lemon upright, cut it into quarters, and slice each wedge in half lengthwise. For twists, cut the lemon in half widthwise and slice off a 0.25 in (0.64 cm)-thick round. Make a cut down the center, remove the pulp, then twist the rind.

How to cut bar cookies cleanly? ›

To make precise and accurate cuts, insert three toothpicks, evenly spaced, along all four sides of the cooled bars. Cut diagonally across the bars beginning in one corner—the lower left corner is an easy place to make your first cut—and cutting from one toothpick to the next closest on the perpendicular side.
