The recipe, step by step
When life gives you lemons, you make lemon bars. Surprisingly simple to make, with the perfect amount of shortbread crust to lemon filling ratio. I8
I played with this recipe until it turned out exactly how I wanted it to. The buttery shortbread biscuit base is so good, it has the right amount of sweetness to offset the tart lemon filling.
As well as lemon juice in this recipe, I use zest to give it a real zingy tang. If you love lemons you are going to love this dessert, if on the other hand you want a milder lemon taste it’s easy to just reduce or omit the zest.
If you like the sound of these delicious lemon bars, you might also like my moreish lemon biscuits or my lemon crinkle cookies.
Recipe Highlights
- EASE: super simple.
- TASTE: tart lemon filling with the perfect balance of sweetness on a buttery biscuit base.
- TEXTURE: silky smooth filling on a shortbread biscuit crust.
- SERVING: perfect on their own or with a cup of tea.


Ingredients
For this lemon bar recipe, all you need are these ingredients:
- Butter – adds structure and a rich butter flavour to this biscuit base. I use good quality salted butter for most of my baking as it intensifies the flavours, but feel free to use unsalted if you prefer, keeping in mind that good quality makes all the difference in taste.
- Caster or granulated sugar – adds structure, moisture and sweetness to the bars. Getting the right balance of sweetness to tartness is a personal preference. It may be tempting to reduce the sugar, but it also adds structure and moisture.
- Medium eggs – add structure and creaminess to the filling.
Nigel Recommends
The Vanilla I Recommend
I recommend Taylor & Colledge vanilla products because they add a delicious depth of flavour while enhancing the other ingredients in the recipe. Choose from pure vanilla extract, vanilla paste or vanilla pods, depending on the recipe and the intensity of flavour you prefer.
- Plain or all-purpose flour – adds that perfect crumb to the biscuit base and structure to both the base and the filling.
- Lemons – are our star ingredient in this recipe, I prefer to use fresh organic lemons when I am using the zest in a recipe.
- Icing sugar (powdered sugar) – is perfect for dusting the tops of our luscious tangy lemon bars.
- Salt – Dont forget the salt – I highly recommend adding a generous pinch of salt to your desserts. Salt helps balance sweetness and richness while enhancing the other ingredients and bringing out the best flavours in the recipe. Although it may seem contradictory, a small amount of salt can also make sweet foods taste sweeter. Sodium can influence the way our taste receptors respond to sugars, helping us perceive sweetness more clearly. The key is to add just enough to enhance the flavours without making the dessert taste salty.The result is that salt not only alerts our ‘salt sensitivity’, but also our ‘sweet sensitive’ taste buds.
I recommend Maldon Sea salt flakes or Cornish sea salt.
Variations
Try some of these flavour twists.
- Lavender – adds an aromatic mild floral fragrance and taste to this classic. Prior to making the filling blend one third of the sugar with 1 tablespoon of lavender in a food processor for 15-20 seconds. Then add this back to the rest of the sugar and follow the recipe.
- Almond essence – add a few drops of almond essence while beating the butter and sugar together in the biscuit base.
- Summer fruits – make the filling as per the recipe. Place 60g (1/2 cup) of raspberries or blueberries into a small bowl and coat in a little flour to help reduce any moisture. Then add them to the finished filling mix and pour on to the biscuit base once pre-baked.
- Citrus fruit – try orange or pink grapefruit bars. They are exactly like lemon bars, only not as tart or acidic. Simply replace the lemon juice and zest with either grapefruit or oranges.

Storage and Freezing
These lemon bars are great for making ahead of time. Store them in an airtight container in the fridge for up to 5 days.
Freezing: It is best to cut them into individual size portions and then wrap each bar with cling film (do not dust with icing sugar), store them for up to 3 months. To defrost, either place the bars in the fridge overnight or leave on the counter to come to room temperature. Serve dusted with icing sugar.


Tools You’ll Need
Here is a list of some kitchen equipment that I use and recommend for this recipe.
Easy to use – simply slice the lemon in half and then place it inside the dome with the cut-side facing down- Bring the two handles together to start juicing- The juicer will turn the lemon inside-out to get every last drop.
- Pyrex Glass Measuring Jug, 1L – I think I have said it before that I am not a big fan of plastic, so I like this type of glass measuring jug for calculating my liquids.
- Square cake pan
My recommendation: Loose Base Square Cake Tin, Professional Gauge Carbon Steel with Eclipse Non-Stick Coating, 20 cm x 20 cm / 8″ x 8″ Cake Pan; Cake Pan, Ideal for bakes and celebration cakes – A great size and good quality non-stick pan for all your traybakes, bars etc…
Recipe Tips
Line your baking pan or silicone mould with baking parchment. It makes it so much easier to remove your finished dessert in one piece once baked and cooled.
Use good quality butter for this recipe, it makes all the difference to the finish result.
I highly recommend using only fresh lemon juice and, where possible, organic lemons because we use the zest.
This is not essential but, I like to use a large measuring jug to mix my lemon filling ingredients in. It makes it easier to fill the baking pan without having to remove the baked biscuit base from the oven and then juggle with it placing it back into the oven.
Don’t rush the chilling time for the bars once baked. This gives them time to set, and overnight in the fridge is best.

Shortbread biscuit base
- 125 g butter
- 50 g caster sugar
- 1 pinch sea salt
- 1/2 tsp pure vanilla extract or 1/4 tsp of vanilla paste
- 180 g plain flour (all-purpose)
Lemon filling
- 4 medium eggs (200g total)
- 375 g caster sugar
- 2 pieces of organic lemon (150ml juice and zest)
- 45 g plain or all-purpose four
- 1 pinch sea salt

- 3 tbsp icing sugar (US powdered sugar)
Preparation
- Preheat the oven to 180°C fan / 400°F / Gas 6.
- Line a baking pan 20x20cm (8x8inch) with baking parchment.
- Shortbread biscuit base: In a medium bowl or stand mixer, beat together the butter and sugar until smooth and creamy.
- Then add the vanilla, salt and sift in the flour.
- Continue beating until the mixture comes together. The mixture will be crumbly.
- Pour the dough into your prepared baking pan and press it down into an even layer.

- Use a fork to make a few holes in the crust and bake for 10 minutes.

- Lemon filling: While the base bakes, place the eggs, sugar, salt, flour, the zest and juice of 2 lemons into a large bowl or measuring jug. Whisk until just combined, the mixture will be thin.
- Once the biscuit base is baked either open the oven and pour the filling directly on top of the biscuit base for ease or remove it from the oven and pour the lemon filling over the biscuit base.
- Baking: continue baking for 20-25 more minutes or until the centre is slightly firm to the touch and no longer wobbles. Once baked remove from the oven and allow to cool.
- Once completely cool, transfer to the fridge to set for 2 hours (or overnight).
