This Lemon Bar Recipe is the quintessential party dessert, baking up perfectly sweet while still lemony and tart. Very few, simple ingredients are needed to make this recipe from scratch and they always are the first to go at any get-together. 

The trouble with lemon bar recipes on the internet is finding the right one with that perfect balance between the buttery and sweet shortbread crust with the gooey, tart and sweet (but not too sweet) very lemon filling. There aren’t that many variables, but not having enough lemon juice or even too much can give you lackluster lemon bars. It’s taken me a little time to get there, but we made it and today is the day you all get this fabulous lemon bar recipe that (hopefully) won’t let you down.

Lemon Bar Recipe

Using simple everyday ingredients, you can have these tasty lemon bars too! Start by gathering up these items:

  • Salted Butter – I love using *salted* butter because it helps offset all the sweet. I know it’s a little bit of a controversial ingredient, but it’s just what I prefer. Unsalted butter is just fine too.
  • Powdered Sugar – I also really love using powdered sugar in the shortbread base because it’s finer texture makes the shortbread a little more tender which works perfectly with the slightly gooey and sticky lemon filling. Plus to top it all off, dust with even more powdered sugar.
  • All-Purpose Flour – this is used for the shortbread and to thicken the lemon filling.
  • Vanilla – for flavor in the shortbread.
  • Granulated Sugar – this lemon bar recipe has the perfect amount of sugar to the tart lemon flavor.
  • Eggs – for thickening and setting that top layer through the baking process.
  • Lemon Juice – lip-smacking lemon juice. Fresh is best!!!

How to Make Lemon Bars

  1. Spray 8×8 or 9×9 square glass baking pan with nonstick cooking spray and line parchment paper (optional). Lightly spray parchment with more cooking spray and set aside. Preheat oven to 350 degrees.
  2. In a medium-sized bowl, mix butter, flour, powdered sugar, and vanilla until a dough starts to form. If you notice the dough not coming together, your butter may be too cold. Mix with your hands so the heat from your hands can help bring the dough together.
  3. Press dough evenly into the bottom of the prepared pan. Bake 12-15 minutes or until edges are barely golden brown.
  4. While crust bakes, make the lemon filling. Whisk sugar together with lemon juice, eggs, and flour. Once the crust is done baking, pour lemon filling over hot crust.
  5. Bake 20 minutes or until set. Cool the lemon bars completely.
  6. Cut into 16 even squares, sprinkle generously with powdered sugar and serve!

Lemon Bar FAQ’s

Can I double this lemon bar recipe? Yes! The recipe as written is meant for a square 8×8 or 9×9 baking dish. If you’d like to double it, bake in a 9×13 pan. The pan is not exactly double, but works perfectly fine.

Do I have to use a glass pan? No, but I would strongly recommend it. Metal pans tend to give off a metallic flavor to the lemon bars after baking, so to avoid that, bake in glass.

Why do I have a thin, white layer on top of my lemon bars after baking? These are air bubbles that got caught in the lemon filling! Having these air bubbles show up on top of your baked lemon bars is completely normal! It won’t change the taste and is nothing that a little extra powdered sugar can’t cover 😉 

Do I have to use fresh lemon juice? Yes! If you want that super tart and sweet balance that lemons bars are known for, you need to use the real stuff. Please please please don’t use the kind from the bottle!

How many lemons will I need? There are large and small lemons on the market and all will yield different amounts of juice. I would recommend getting 3 large lemons for this recipe to juice. I usually am ok with just two, but sometimes you get a less juicy lemon and will need to top off your half cup with an extra squeeze from that third one.

How to Make Lemon Bars

Storing

I like storing my lemon bars in an airtight container in the fridge. When you pull them out, you may need to add another light layer of powdered sugar, but besides that, they should last a good week in the fridge (if you don’t eat them all first!)

Freezing

This lemon bar recipe can be made ahead of time by freezing it for up to 3-4 months.

To Freeze. Cut the cooled bars (without powdered sugar) into squares, then place onto a baking sheet. Freeze for 1 hour. Individually wrap each bar in aluminum foil or plastic wrap and place them into a large plastic bag to freeze.

To Serve. Thaw in the refrigerator overnight, then dust with powdered sugar right before serving.

    I made these Sunday and they are appropriately titled “Perfect” lemon bars as they are! Scrumptious!!! Thank you Lauren for another awesome recipe! Good luck with your pregnancy.

    I wanted to make some of these recently but couldn’t find my recipe. Now I see this has JUST been put out so I’m excited about that! Thank you!

    1. Kirsten

      This might be a silly question but If I doubled this recipe should I double the baking time as Well for both crust and filling?

      1. Lauren

        No, don’t double the baking times. If anything you’ll have to add an additional 5-10 minutes to ensure the filling is set, but that’s it!

        1. Christie Thomas

          I have a doubled batch in the oven just now. I have added an additional 15 minutes and they still aren’t done. Any ideas? The first batch I made, a single batch, came out perfectly.

    This is the Mary Poppins of Lemon Bars- practically perfect in every way! The shortbread crust is the perfect compliment to the tangy lemon flavor. Thanks for making this recipe for me Lauren 😉

    Lemon bars are one of my favorite desserts and I love that this makes a smaller batch than my usual recipe! I can’t wait to try them!

    Made this recipe and loved it. Perfect amount of shortbread to lemon. An old recipe that I’ve used had lemon zest and I was worried these might not be lemon-y enough. But, they really were perfect. Thank you!

    Tasted very egg-y. Luckily I was only making these for fun. I think I will stick to the Betty Crocker recipe that uses less eggs. Darn.

    Sorry, these were not good. I followed the recipe exactly with powdered sugar and juice from 2 fresh large lemons.
    They were so bitter! We were taking them to a potluck dinner. My husband said not to take them they are too tart!
    I am going to have to stop at the grocery store and buy something ready made.

    1. Jackie Scott

      Bitter? If recipe was followed they were perfect balance of sweet and tart. Thanks Lauren. My fiancé loved them!

    Extremely delicious and easy – 1st time making Lemon Bars. Such a difference from store brought. It took 35 mintutes in my oven as its slow.I have a lemon tree. Many thanks for the recipe.

    The crust qas amazing but the filling was off too much lemon actually burnt our throats had to buy store made as this was for a party

  11. Laurel brownscombe

    Messed that one up. When pouring in the lemon mixture it made the shortbread flip up. There was nothing I could do about it so am still baking it hopefully it will come out edible

    1. Patricia G

      That happened to me too! They are still in the oven. So we’ll see what they turn out like. Most other recipes do cook the shortbread base for longer so I wonder if the time is a typo…as someone mentioned. Oh well live and learn.

    I’d give 4.5 stars if allowed. Thought this was a very good recipe, and was quite tasty. But I LOVE a stronger lemon flavor, and would not waste that lemon zest! I added 1/2 teaspoon of lemon zest from those lovely fresh lemons to amp up the lemon. Next time I’ll add more!

    I have been obsessed with lemon bars during the lockdown because lemons are easily available and we are out of vanilla essence for other desserts! I have tried 4 recipes so far and this is has turned out the best and is also the easiest! I would prefer the sugar to be slightly less as the bars a little too sweet for my liking and I did not even dust them with sugar. But again, I do like my desserts less sweet. But otherwise, this recipe is perfect.

    I made these today and the only thing I did different was add lemon zest to the filling and OMG they are sooo good! Thank you for sharing this recipe.

    This is a great recipe, I used a 9 x 9 glass dish with parchment and they lifted very nicely. I only made two tweaks – I added roughly a tablespoon of lemon zest and used pastry flour in place of all-purpose flour. I find the latter gives it a slightly more richer crust. Ideal balance of tangy and sweet, perfect for spring!

      I am 50, and made these for the very first time ever. Shame on me, because they are amazing!! I doubled my batch and cooked the crust and the bars longer. I was worried because I wasn’t quite sure what “set” meant. It jiggled when I removed it from the oven, but set perfect while cooling. I always loved lemon squares growing up, so glad I FINALLY made them.
