The best lemon bars are just sweet enough to temper lemon’s acidity while heightening its heady tang. Adding zest to the curd would have detracted from its comforting smoothness with chewy bits. Instead, the wisps of lemon peel bake into the cookie, which is snappier than classic shortbread to provide a contrast to the filling’s softness. Rather than cutting cold butter into flour and powdered sugar for a crumbly bottom as many recipes do, this version combines melted butter with flour and granulated sugar for a sturdy — and simpler — dough. After setting in the oven, the base is covered with the just-as-simple lemon mixture while still hot. Doing so ensures that the layers meld together into a textural ombré so that each bite starts with melt-in-your-mouth curd and ends with a satisfying crispness.

Preparation

  1. Step 1

    Prepare the crust: Heat the oven to 350 degrees. Line the bottom and sides of a 9-inch square metal pan with foil. Lightly coat with nonstick cooking spray.

  2. Step 2

    Combine the butter, sugar, vanilla and salt in a large bowl. Finely grate in the zest of 2 lemons (reserving the zested lemons for the lemon layer), then mix until well combined. While stirring, gradually add the flour and stir just until the dough comes together into a mass. Scrape into the prepared pan and gently press the dough into an even layer.

  3. Step 3

    Bake until the center is dry and the edges are golden, 15 to 18 minutes.

  4. Step 4

    While the crust bakes, make the lemon layer: Squeeze ⅔ cup juice from the zested lemons and more fruit if needed. In the same bowl used for the crust, whisk the sugar and flour. Whisk in the eggs until smooth, then whisk in the lemon juice just until incorporated.

  5. Step 5

    When the crust comes out of the oven, whisk the lemon mixture again and then gently pour it over the hot crust. Turn the oven down to 300 degrees.

  6. Step 6

    Bake until the lemon layer is set around the edges and jiggles a tiny bit in the center, about 20 minutes.

  7. Step 7

    Cool completely in the pan, then refrigerate uncovered until cold and fully set, at least 3 hours. Use the foil to lift the bars out of the pan to slice. Serve cold or at room temperature. The bars can be refrigerated in an airtight container for up to 5 days. If you’d like, dust with powdered sugar right before serving.

Cooking Notes

I seriously will never understand why people comment on the amount of fat and sugar used in a cookie or cake recipe. This is a treat, for crying out loud, not a recipe for bran flakes. A serving of these lemon bars is 201 calories and 4 grams of saturated fat. A Cliff bar has more calories and almost the same amount of fat. Have a lemon bar, eat a salad, go for a walk or a run, enjoy life.

This recipe is very similar to one for Danish Lemon Bars shared by a friend over 40 years ago, especially the composition of the crust. I've enhanced the crust both with lemon zest and by substituting almond meal for 1/4 to 1/3 of the flour. Increasing the amount of lemon juice in the filling, as Ko's recipe does, and decreasing the sugar enhances the lemony-ness of the final product.

For the crust, zest the lemon into a bowl with the measured amount of sugar, then rub the mixture together with your fingers. The oils get released into the sugar, further enhancing the lemon flavor. Then add the rest of the ingredients. By the way, the amount of lemon juice needed for the lemon layer (2/3 cup) is missing from the ingredient list. It is listed in the directions though.

STEP 8: Put lemon bar in a bowl and cover with fresh blueberries and whipped cream.

These are the best lemon bars I've ever tasted! Sweetness nicely tempered both by the acidity of the lemons and by the butteriness of the cookie base. And the recipe is so easy! The only thing which surprised me is that the cookie base puffed up like a big bubble while baking. I had to prick it all over with a fork to deflate it. Next time I'll put fork marks all over before it goes into the oven.

Incredibly delicious!!! Ended up using 4 lemons for juice. Used an 8x8 ceramic and came out great with a thicker curd layer after baking about 24 minutes. Usually I'm disappointed with a lack of acidity or citrus flavor and this did not dissappoint. Wouldn't change a thing.

I double line the pan with parchment so that when it is time to cut you don't have to fight with the edges and all of the bars are pretty.

It's easy. And yes, it's a wonderful recipe. Avoid one mistake I made. I took the crust out of the 350 oven, poured the lemon layer ontop and then waited until the oven thermostat said it had gotten down to 300 before putting everything back in to finish baking. Wrong. In the time the oven cooled to 300 the crust had shrunk, allowing the lemon mixture to seep along all 4 sides and get underneath the crust. Be brave--reset, put everything back in, and check carefully for doneness.

Please do NOT use Stevia if you have never used. I used it on recommendation for a recipe and it RUINED it. It has a horrible chemical aftertaste to me. Make sure you like Stevia before you use it in this, and any other recipe. Personally, I'd rather have the sugar and butter. They're lemon bars, you don't eat them every day!

Oil changes the texture of the crust, it bakes differently than butter does. Personally, I would just reduce the amount of sugar to 1 cup in the filling, try it this way and if still too sweet, reduce it to 3/4 cup. Personally, I do not like the taste of Stevia.

As long as you are using a metal sheet, it does not matter. The crust will not set at 350F in 15 minutes if you are using glass or ceramic.

For the Lemon Layer 250g (1¼ cups) Granulated Sugar 33g (¼ cup) All-Purpose Flour 4 large Eggs, at room temperature �� cup of Lemon Juice [<-- omitted] Powdered Sugar, for dusting (optional)

Way way too much sugar. God awfully unhealthy. Consider sweetener options (like a pure Stevia [not the goop they sell in grocery stores which is 1/2+ glucose in various forms]). Same with butter. Use half or less amount in recipe. Add a healthy, but mellow oil, like a high quality canola. Still turns out delicious. One of my favorite treats.

I actually prefer the lemon bar recipe that I have evolved over time. It uses a gingersnap crust, which really adds to the overall taste.

The recipe says 2/3 cup.

This curd is just wonderful. I love the taste of tart lemons and this is it! And, the curd is super simple to make. Made it exactly as written. This is a keeper.

I enjoy lemon bars very much and this recipe did not disappoint. I used slightly less sugar in the filling portion (1 cup instead of 1.25 cups) and the result was a deliciously tangy (but still sweet) filling. If you're someone who likes a sweeter lemon bar, go for the full amount of sugar, else it might be too sour for you!

These are fantastic. Has anyone frozen them successfully? I freeze so many things, but not sure how these will survive the freezer.

After trying this recipe as is a few times I made a few tweaks . One I reduced the sugar in the curd by 50 grams as I use Meyer lemons and they tend to be less sour. Two I grated lemon zest of 4 lemons into the total amount of sugar and let it sit for an hour as it draws out the lemon oil from zest. More lemon flavor. Three I added a tsp of cardamom to crust, again enhances lemon. And finally, I sprinkle on sea salt with powered sugar, personal preference.

These are incredible. They look beautiful and taste delicious. I followed the recipe exactly and it turned out perfectly. Next time I’m going to do a layer of parchment after the foil (a suggestion I saw from another comment) just to make the peeling away a little easier. I will definitely make these again. So so good!!

Simple, intensely lemon flavored, lovely looking. Butterfly I used equal parts flour and cornstarch in the lemon filling but it was probably not necessary.

I followed the recipe precisely, except I did use a fork to poke a few holes in the shortbread before baking it. These were excellent. The shortbread makes a nice counterpoint to the tart lemon filling. I’ve seen a lot of discussion about adding more lemon juice. I used the recipe amount and these were tartness perfection.

I made lemon squares today. Very tasty! Very lemony! Beautiful to look at! Lovely recipe, which was easy to follow. I added to the crust the zest of 3 lemons rather than 2 as I love lemon zest! I forgot to line the baking dish with foil, which resulted in difficulty removing the chilled bars. As such I strongly recommend following Genevive Ko’s instructions and using lining for easier removal of lemon bars from baking dish. I will make again to bring to a bridal shower this weekend.

I made with meyer lemons from my garden. Substituted 1/2 cup almond flour for some if the flour in the crust and didn’t overbake it. Cut back sugar in filling to a cup and added a little for lemon juice. Only had round tart pan. Came out fantastic like the best lemon tart! Will make again!

Can you make these ahead of time (i.e bake Friday, serve Sunday?)

Yes. I recently made two batches on a Thursday. We ate most of the first batch on Thursday. But we ate the second batch at a gathering on Sunday. There was no difference in taste. I did store them in the refrigerator.

I’ve made these twice, they’re delicious and very easy to make- and I’m no baker. Takes 27-28 minutes at 300 degrees for curd to firm up enough in my oven. Next time I’ll try rubbing lemon zest with sugar for the crust, and adding the zest from the 2 additional lemons to the curd, as others have suggested.

This has become my go-to lemon bar recipe. I love how the shortbread-style crust holds up well against the lemon curd. This recipe is easier, tastier, and presents better than many lemon bar recipes. Even my husband has commented that this recipe is far superior than any other lemon bar I have made more him. Thanks!

Perfect lemon bars! I used an 8" x 8" square pan, which added an extra 10 minutes to the cooking time (I kept checking every 5 minutes after the initial 20 minute suggested time elapsed). I made this with Meyer lemons gifted from a friend's tree and they worked wonderfully in this recipe. I also used 4 lemons (they were various sizes) to get to the 2/3 cup of juice. This was my first time (!!!) making lemon bars and I can't recommend this recipe enough. Thank you Genevieve!

Seems like a lot of salt in crust. Other simikar recipes use a lot less!

Seems like? Did you make this recipe? If you prefer another recipe, use another recipe!

Delightful!
