Ingredients You’ll Need
- For the Shortbread Crust:
- 200g unsalted butter, softened to room temperature
- 100g caster sugar
- 250g plain flour
- ¼ teaspoon salt
- For the Lemon Filling:
- 4 large eggs
- 300g granulated sugar
- 60g plain flour
- 180ml freshly squeezed lemon juice (from about 4-5 lemons)
- Zest of 3 lemons
- A pinch of salt
- For Dusting (optional but recommended):
- Icing sugar, for finishing
Tip: For the brightest flavour, always use fresh lemons. Bottled lemon juice can taste flat and will not give you the same vibrant, zesty kick that makes these bars so special. I make this at least once a week – it’s become a family favourite, and using fresh citrus makes all the difference.
How to Make Homemade Lemon Bars
- Prepare the Oven and Pan: Preheat your oven to 180°C (160°C fan). Line a 20x20cm square baking tin with parchment paper, leaving an overhang on two opposite sides. This will act as your handles to lift the bars out later. The paper should feel snug against the sides of the tin.
- Make the Shortbread Crust: In a medium bowl, cream the softened butter and caster sugar together with a wooden spoon until pale and fluffy. The mixture should look light and feel smooth, not grainy. Add the flour and salt, and mix until a soft, cohesive dough forms. It will be slightly crumbly but should hold together when pressed.
- Press and Bake the Crust: Transfer the dough into your prepared tin. Press it evenly into the bottom using your fingertips or the flat bottom of a glass. The surface should be flat and compact, with no visible cracks. Bake for 18-20 minutes, or until the edges are just turning a pale, golden brown. The centre will still feel slightly soft but will firm up as it cools. You should smell a rich, buttery aroma.
- Whisk the Lemon Filling: While the crust bakes, make the filling. In a large bowl, whisk the eggs and granulated sugar together until well combined and slightly thickened, about 1 minute. The mixture should look pale and feel smooth. Whisk in the flour, salt, lemon juice, and lemon zest until completely smooth. The batter will be thin and smell intensely of fresh lemons.
- Pour and Bake the Bars: Pour the lemon filling over the warm, pre-baked crust. The warm crust helps the filling set evenly. Bake for 20-25 minutes. The filling should be set around the edges but still have a slight jiggle in the very centre when you gently shake the pan. The top will look matte, not wet or shiny, and the surface will feel firm to a light touch. A faint, glossy sheen is a sign it is done.
- Cool and Chill Completely: Allow the bars to cool to room temperature in the tin on a wire rack. Once cool, transfer the tin to the refrigerator and chill for at least 2 hours, or up to overnight. This step is crucial for clean, neat slices. The bars should feel completely cold and solid to the touch.
- Slice and Serve: Using the parchment overhang, lift the entire block of lemon bars out of the tin and onto a cutting board. Using a sharp, non-serrated knife, slice into 16 squares. For the cleanest cuts, wipe the knife blade clean between each slice. Dust generously with icing sugar just before serving.
Tips From My Kitchen
- Why We Chill the Dough Crust: While you do not need to chill the dough before baking, pressing it into the tin with cold fingertips helps prevent the butter from melting prematurely. This ensures a tender, sandy shortbread crust rather than a greasy one. The cold butter creates steam pockets in the oven, giving you that perfect crumbly texture.
- Use Room Temperature Eggs: Cold eggs can cause the filling to seize or become lumpy, resulting in a less smooth texture. Let your eggs sit on the counter for 15-20 minutes before whisking. This allows the sugar to dissolve more easily and creates a homogenous, silky filling that bakes evenly. If you are in a hurry, place the eggs in a bowl of warm water for 5 minutes.
- Don’t Over-Bake the Filling: The biggest mistake is over-baking, which leads to a rubbery, curdled texture. The filling should be just set; a slight jiggle in the centre is your cue to take it out. The residual heat will finish the cooking process as it cools. The top should be matte, not glossy or cracked. If you see cracks, the bars are overdone.
- Chill for Clean Slices: This is non-negotiable for a professional-looking result. Chilling firms up the filling and the butter in the crust, allowing the knife to glide through cleanly without dragging or crumbling. I always chill for a minimum of 2 hours, but overnight is even better. For absolute perfection, you can pop them in the freezer for 30 minutes before slicing.
- Scale for Meal Prep: This recipe doubles beautifully. For a larger batch, use a 23x33cm tin and increase the baking time for the crust by 5 minutes and the filling by 8-10 minutes. Watch for the same visual cues – a matte surface and a slight jiggle in the centre. You can then freeze the entire block or individual slices for up to 3 months.

Frequently Asked Questions
Can I use bottled lemon juice instead of fresh?
While you can technically use bottled juice, I strongly advise against it for the best flavour. Freshly squeezed lemon juice provides a bright, clean acidity that is essential for these bars. Bottled juice often contains preservatives and can taste metallic or flat, resulting in a less vibrant and satisfying dessert.
Why is my lemon filling not setting?
This usually happens for two reasons: under-baking or skipping the chilling step. Ensure the filling has a slight jiggle in the centre when you remove it from the oven; it should not be liquid. After baking, the bars must be refrigerated for at least 2 hours to allow the structure to fully set. Patience is key here.
How should I store leftover lemon bars?
Store them in an airtight container in the refrigerator for up to one week. To prevent them from drying out or absorbing other fridge odours, place a piece of parchment paper between layers. They are best enjoyed cold, straight from the fridge, but you can let them sit at room temperature for 10 minutes to soften slightly.
Can I freeze Homemade Lemon Bars?
Absolutely, and they freeze beautifully. Once the bars are fully chilled and sliced, place them on a baking sheet lined with parchment paper and freeze until solid, about 1-2 hours. Then, transfer the frozen squares to a freezer-safe bag or container. They will keep for up to 3 months. Thaw individual bars in the refrigerator for a few hours before serving.
My crust is too crumbly. What went wrong?
A crumbly crust typically means the dough was not pressed firmly enough into the pan, or the butter-to-flour ratio was off. Ensure your butter is properly softened and you are pressing the dough down with even, firm pressure. Using the flat bottom of a glass helps compact it. Also, double-check that you are using plain flour, not self-raising.
