Easy Lemon Bars

With a shortbread base and lemon curd topping that’s tart and not-too-sweet, these Lemon Bars are really easy to make. Tastes like a Lemon Tart – but so much more straightforward!

Lemon Bars

These Lemon Bars are like a simpler form of Lemon Tart which is made with a shortcrust pastry that’s chilled, rolled out, blind baked then cooled before filled with lemon curd, then baked again, then cooled.

Beautiful. Elegant. Impressive.

But for the days when you don’t have time for all that, Lemon Bars is what you make! It’s incredibly simple: the base is blitzed in a food processor, pressed in a pan, baked, then just pour over a simple lemon curd mixture and bake again.

LOVE the lemon curd! Jammy, a bit custardy, tangy and not-too-sweet. Hits the spot!

Ingredients in Lemon Bars

Here’s what you need to make these Lemon Bars.

FOR THE SHORTBREAD BASE

The same ingredients I use in my shortbread – because that’s exactly what we’re making!

Flour – Just regular plain / all-purpose flour.
Rice flour – Makes the shortbread more crumbly. I don’t use it in my classic shortbread cookie recipe because it doesn’t improve the end result (due to the particular method I use). But for the quick ‘n easy food processor blitzing method used in this recipe, it helps keep the shortbread base “short” (ie crumbly), the signature texture we all know and love about shortbread.

Substitute with cornflour / cornstarch which yields a very similar result, or even ordinary flour will work fine (the base will not be quite as crumbly like shortbread, it’s more like a vanilla cookie).
Butter – Cold, unsalted, cut into cubes to blitz into sand with the flour.
Icing sugar / powdered sugar – The fine grains are required to make tender, crumbly, melt-in-your-mouth shortbread. Regular sugar makes tougher shortbread – that’s not what we want! 🙂
Pinch of salt brings out the other flavours. Standard practice in sweet baking – doesn’t make it taste salty.

LEMON CURD FILLING

In my “proper” Lemon Tart, I ask you to separate eggs and use extra egg yolks for the lemon curd. Not today! Sticking with whole eggs.

Eggs – 3 large ones, which are 55 – 60g / 2 oz each, sold in cartons labelled “large eggs”. No need to bring them to room temperature (which I usually call for in baking recipes!). The eggs set the lemon curd when baked.
Caster sugar / super fine sugar if you’ve got it, because the finer grains ensures it dissolves into the curd more easily. However, regular sugar (granulated sugar) is fine too.
Flour – Just a bit helps to ensure the curd sets properly. We don’t use flour in the Lemon Tart filling because it’s made “properly”. But today, we’re going easy!
Fresh lemon! We’re using the zest and juice today. Zest for beautiful lemon flavour, and the juice for tang!

Making lemon bars

Promised easy, and easy it is! Here’s how to make this lemon bars:

SHORTBREAD LEMON BAR BASE

In my pre-appliance days (read: when I was a poor uni student), I used to make shortbread using my fingers to rub the butter into the dry ingredients. These days, I’m lazy and use my food processor. Few pulses, and it’s done. Bonus: no worries about hot little fingers melting the butter!

Blitz – Put the shortbread ingredients in a food processor with the standard “S” blade. Blitz 5 to 10 times until it turns into a loose sandy mixture.
Press – Pour it into a paper lined 20cm/8″ pan with overhang so you can lift the Lemon Bars out once set. Spread the base mixture out then use something with a flat base to press it in firmly. I use a measuring cup.

⚠️ Be sure to press it firmly right into the corners and right up to the wall of the pan so the lemon curd won’t leak down the sides and make the base soggy.

Bake for 20 minutes or until the edges are light golden.
Remove from oven and fill with curd straight away. ⚠️ Don’t let it cool as the base will shrink, causing the curd to run under the base which will make it soggy. Been there, done that!

Lemon curd – While the base is in the oven, whisk the lemon curd ingredients together.
Pour the filling onto the base.
Bake for 20 minutes until the top is set but still soft. There might be a small crack or two on the surface, that’s entirely normal and gets covered up with a dusting of icing sugar!
Cool – Fully cool on the counter then refrigerate for at least 2 hours before slicing to serve!

Optional – To make it pretty, dust with icing sugar. It will sweat, so do this just before serving.
