Shortbread and a recipe for shortbread should be simple, but getting that perfect crumbly, buttery texture can be surprisingly tricky. This guide breaks down everything from the sacred 3-2-1 ratio to choosing the right ingredients, whether you’re in Bristol or Boston.
3:2:1 – The Golden Ratio That Never Fails
Shortbread can seem like a magic trick passed down through generations, and honestly, that’s because it is. Your gran probably didn’t have exact scales or fancy gadgets – just a feel for butter, sugar, and flour, and a knack for getting it just right.
Three Flour. Two Butter. One Sugar.
Flour, butter and sugar. Three ingredients – that’s it. The holy trinity of crumbly happiness.
The Core Method: Gran’s Wisdom
Use your hands, not just machines
Your gran used her hands and she didn’t measure down to the gram she just knew when the dough felt right. You don’t need a fancy mixer, either. Using your hands gives you instant feedback.
If you insist on gadgets, fine: use a mixer for the butter and sugar, then switch to a wooden spoon. Machines don’t have instinct – you do.
The Big Don’ts: Handle With Care
Do not – I repeat – do not overwork the dough. The second you start kneading it like you’re making pizza, you’ve lost it. Gluten will form, and you’ll end up with something that more like a cracker instead of crumbling like a dream.
Also, go easy with the flour dusting. Too much and your dough turns into sandy sadness.
Bake low and slow (160°C fan)
Bake low and slow (160°C fan hits the spot here), and pull it from the oven when it starts to blush gold, not burnt brown.
And, if you want, scatter a pinch of coarse sugar over the top before baking- it sparkles, it crunches, it’s all kinds of fancy without trying too hard.
The Fork Holes Are Not Just Decorative
Poke those little fork holes across the top – it’s not just out of tradition but to let steam sneak away so your shortbread stays perfectly flat and cooks evenly.

Ingredients
- 150g/6oz plain flour
- 100g/4oz unsalted butter, softened
- 50g/2oz caster sugar, plus extra to finish
Method
Preheat the oven to 160C/140C Fan/Gas 3.
Beat the butter and the sugar together in a bowl until smooth. (You can do this in a food processor if your butter is a bit cold.)
Stir in the flour until thoroughly combined. (If you are using a food processor, you can add the flour in this way.) Turn onto a clean work surface and knead the dough just enough to bring the mixture together in to a smooth ball of dough.
Use a rolling pin to gently roll out until the dough is 1cm/½in thick.
Cut into shortbread rounds or fingers and place onto a baking tray lined with baking paper. Sprinkle with caster sugar and chill in the fridge for 20 minutes.
Bake in the oven for 25–30 minutes, or until pale golden-brown. Set aside to cool on a wire rack.
The Best Flour for Shortbread
THE RULE: You want low-protein plain flour.
For a tender, crumbly shortbread use a low gluten, low-protein flour like cake flour or a pastry flour (with a protein content of around 6-7%) is best.
For a chewier cookie use a high gluten plain flour with a high protein content, such as bread flour.
For those wanting to avoid gluten altogether, gluten-free flours like rice or a blend of gluten-free flours can be used
Just don’t use self‑raising flour. This isn’t a sponge cake mission. No one wants puffy shortbread.
Picture this: You’re standing in the baking aisle, deciding between flours, and the world’s your pastry playground. Your kitchen might be in Birmingham, Boston, Brisbane or Berlin, but the mission’s the same-chasing that golden, tender, impossibly buttery shortbread that tastes like home, no matter where you are. Let’s make it happen.
United Kingdom & Ireland
You’re scanning the shelves in Tesco, Sainsbury’s, or Waitrose. You want plain flour – the soft, low-protein stuff that crumbles under your touch.
- Homepride and Allinson? Classic picks; they’re like old friends.
- The supermarket’s own brand? Usually spot-on for a cozy bake.
- Fancy it up? Doves Farm rice flour or Waitrose Essentials cornflour, for biscuits softer than a cloud.
United States & Canada
It’s Gold Medal. It’s King Arthur. It’s Pillsbury staring you down, promising airy shortbread that melts away on your tongue before you’ve stopped smiling.
- All-purpose is your wingman.
- Want tender? Bob’s Red Mill rice flour. Feeling chef-y? Softasilk pastry flour is basically shortbread in a tuxedo.
Australia & New Zealand
White Wings or Defiance are your trusty sidekicks; Woolies and Coles brands are always ready for a tea break.
Plain flour is your soulmate, but pick up Lotus Rice Flour or Fielder’s Cornflour for that soft finish you get at Nana’s house.
France & Germany
You’ve got a baguette in one hand, and in the other, Francine T45 or Aurora Type 405 – because a French tea break deserves its own shortbread moment.
Don’t overlook those neat Carrefour or Lidl own-brands, either. Sometimes cheap really is cheerful.
Italy & Spain
No passport required for “Farina 00” or Molino Spadoni, soft as silk and ready for a dolce vita treat.
- Rice flour from Molino Chiavazza? It brings that Scottish crispness.
- El Corte Inglés semolina? Total game-changer for texture freaks.
So whatever’s rattling around in your country’s baking aisle, reach for the flour with the lowest protein you can find, smile at the rice flour standing nearby (that’s your secret weapon), and picture the smell of buttery shortbread flooding your kitchen, wherever “home” is today.
Because the right flour means shortbread that breaks, melts, crumbles, and comforts – the way you remember, and maybe even better than you’ve ever had.
The Best Butter for Shortbread
THE RULE: Use high-quality, unsalted, European-style butter (82%+ fat).
To cut to the chase on which butter to use look no further than Kerrygold Unsalted (83% butterfat).
The emphasis is on UNSALTED. Why? Is the addition of salt the only difference between salted and unsalted butter
Ashia Aubourg of allrecipes.com published an I Tried 13 Unsalted Butter Brands article in a recent article. She baked shortbread with all 13 butters and rated Kerrygold Unsalted a close 2nd. next to a US-only brand.
Also last year (Nov. 2024) New York Times did a “7 Best Butters of 2025” article testing 11 unsalted butters making shortbread – Kerrygold came top.
Both these articles are of course US-focussed but Kerrygold butter is sold in over 60 countries worldwide so you should be able to pick it up no problem.
- The United States: its the number one imported butter brand.
- Germany: Kerrygold is the number one branded butter overall.
- It’s everywhere in the UK and the rest of Europe.
If you can’t get Kerrygold look for brands with higher butterfat content (often 82% or more, compared to the standard 80% in many butters). This butter will generally produce a more tender and crumbly shortbread with a richer flavour.
A lot of people also ask about Lurpak – the standard Lurpak butter – it has a minimum butterfat of 82% – so yes use it your shortbread recipe.
Kerrygold is a good bit cheaper than Lurpak though so, for me, that makes it a winner.
Make Your Own Butter
You can of course make your own unsalted butter. Its dead simple and takes about 15 minutes. But it will be a little more expensive than shop bought and there’s some gear to buy upfront. But you lose out on that superhero element of making your own.
Since heavy cream typically sold in the UK has between 36-40% butterfat, homemade butter can achieve a fat content of up to 85% or more.
