Using fresh lemons is an absolute must for this recipe!

You want to use fresh lemons here! The zest helps give the buttery base a lovely aromatic dose of lemon and the lemon filling just shines with the use of fresh lemons! Reconstituted lemons are a no-no for this recipe. They just taste dull compared to the real thing.

Why youโ€™ll love these Lemon Bars

Two things. The buttery biscuit base at the bottom. And the gooey lemon filling.

  • Buttery, easy to make crust
  • Perfectly lemony and sweet with each bite.
  • Silky smooth lemon filling
  • Perfectly set lemon filling – FOOLPROOF!

The secret to getting silky smooth Lemon Bars

Make sure you donโ€™t overbake your lemon bars! It will result in a rubbery bar. The best way to ensure sure these bake soft and creamy is to

  • Oven temperature – Make sure your oven is set at the right temperature. Use an oven thermometer if youโ€™re unsure if your oven runs at the right temperature.
  • Bake until jiggly in the center – Youโ€™ll know these are finished baking when you move the tin and they jiggle slightly in the middle. They continue baking in the tin after they come out of the oven and will set perfectly as they cool.

There are only 7 ingredients!

  • All-purpose flour – also known as plain flour. You could use cake flour and leave out the corn starch if you wish.
  • Corn starch – also known as corn flour, this helps make the base a little lighter in texture.
  • Powdered sugar – also known as icing sugar, this will help sweeten the base but still make the crumb fine and crumbly.
  • Salt – I use fine salt.
  • Lemons – I used lemon zest in the base to help boost the lemon flavors in these gorgeous bars. I used zest and lemon juice in the filling. The result is that youโ€™re left with a huge flavor punch of lemon.
  • Unsalted butter – Make sure your butter is nice and chill, straight out of the fridge. Cut it into cubes to make it easier to process. Using cold butter will also
  • Caster sugar – also known as superfine sugar, this will dissolve into the filling easier than granulated sugar.

How to make Lemon Bars

Shortbread Base

  • Add the dry ingredients to a food processor and pulse to combine before adding cold butter.
  • Pulse until you reach lentil sized pieces of butter. Itโ€™s going to look crumbly and dry, but trust me, it will bake perfectly!
  • Pour the crumbs into the base and bake until golden (full instructions in the recipe card!)

How to Make The Lemon Filing

  • Mix all of the filling ingredients in a large mixing bowl.
  • Pour on top of the baked base as soon as it comes out of the oven. Bake for 20 minutes. The center will be slightly jiggly.

Cooling Your Bars

  • Allow to cool completely at room temperature before placing in the fridge for 4 hours. Dust with powdered sugar and slice before serving.

How to get perfectly clean bars

Lemon Bars 24 - slicing up perfectly baked lemon bars

Thereโ€™s an easy trick your favorite food bloggers use to get those perfectly clean looking bars for their photos. Simple run your large knife under hot or boiling water, dry carefully with a clean towel and then slice. Clean the knife, run under hot or boiling water and dry before slicing again. Itโ€™s time consuming but totally worth those super sharp looking bars!

Tips and Tricks For Recipe Success!

  • Your shortbread mixture will look super crumbly. Thatโ€™s normal. It all bakes and comes together in the oven. Bake until lightly golden.
  • When mixing your lemon filling, try not to overmix as this can over aerate the mixture which will lead to large bubbles on top of your bars. Still taste amazing through!
  • Youโ€™ll know your bars are finished baking when thereโ€™s a slight jiggle in the center. Theyโ€™ll set perfectly as they cool.
  • Allow to cool to room temperature before placing in the fridge to chill for 4 hours. This will make slicing them up much easier!
  • Donโ€™t overbake your lemon bars or youโ€™ll end up with a rubbery lemon layer instead of something thatโ€™s nice and gooey.
  • Use fresh lemons! Reconstituted lemon juice lacks the flavour punch that fresh lemons give you. And since this is the main selling point of this dessert, you want to make sure you use the best of everything!

Why are there bubbles on top of my lemon bars?

Thatโ€™s normal! The bubbles are the air that you whisked into the lemon filling as it was being baked. Simply let the filling rest for 5 minutes before pouring into the biscuit base, then bake. If they remain after baking, never fear! These will be dusted with powdered sugar and covered up!

Why is this recipe is in grams and not cups?

The short answer is accuracy! It is far easier, more accurate and you get more consistent results when you measure ingredients by weight, especially in dessert and bread baking! I wrote all about this in my post about using digital kitchen scales!

Can I make Lemon Bars in advance?

Yes! These are an easy dessert to travel with which makes the perfect gift giving treat! You can make these up to 3 days in advance. Just donโ€™t dust them with powdered sugar until right before theyโ€™re served!

Instructions

Shortbread Base

  • Preheat a fan-forced oven to 180C / 350F (180C / 395F for no fan). Spray a 20cm / 8-inch square cake tin with oil spray and line with baking paper.
  • Make the biscuit crumb – Add the all-purpose flour, corn starch, powdered sugar, salt, and lemon zest to the bowl of a food processor. Blitz until well combined, about 30 seconds. Add the butter and blitz for about 30-40 seconds until you reach pea sized butter.
  • Bake – Pour into the cake tin and spread out. Press down firmly using our hands or a flat-bottomed glass/measuring cup. Bake for 8 minutes or until light and golden. While the crust is baking, make the filling.

Lemon Filing

  • Lower oven temperature – Lower your oven temperature to 150C / 300F (170C / 340F for no fan).
  • Make lemon filling – Add the lemon zest, caster sugar and flour to a large mixing bowl. Use a whisk to combine. Then add the eggs and lemon juice. Whisk until just combined. Take care not to overmix! We donโ€™t want to over-aerate the filling.
  • Bake – As soon as the crust is baked, pour the filling on top. Bake for 22 minutes or until the middle is set and only has a slight jiggle. The top should barely be golden. Take care not to overbake or it will feel like eating rubber and wonโ€™t be perfectly gooey.
  • Cool down – Once baked, allow to cool at room temperature for 2 hours, then chill in the fridge for 4 hours to set. Dust with powdered sugar and then use a large knife to slice up.
  • For super clean slices – Run a large knife under hot water and dry. Make a slice. Wash under hot running water and dry again before the next slice. This is how to get nice sharp edges!

Notes

Lemons – wherever you buy your lemons, make sure you give them a good scrub under some warm water to rid them of that shiny wax coating they put on them at the store to make them look shiny. Nobody wants to eat that!

The filling is delicious! However i did the paper the same way as you in the video but for some reason my filling leaked beneath the base biscuit layer and then didn’t firm up properly, when i tried to remove and cut everything was a disaster and paper was stuck everywhere and i couldn’t figure it out.
It was a wonderful mess but next time i’ll line the tin differently i think!

I made this today with lemons from our tree. It was so easy and absolutely delicious. I used half the amount of sugar for the filling. Iโ€™ll be making this again for sure.

Made this today and itโ€™s overly sweet, not enjoyable to eat and ended up being thrown out. I think I will make it again but will be reducing the sugar to see how it turns out.

Yeah, this is a sweet dessert lol. Reducing sugar will not result in a dessert stable enough to hold its shape. I understand it’s not for you, but every single recipe is the same. It’s very tart and sweet. Thanks for the 4 stars though!
