Shortbread Recipe | Classic Scottish Butter Shortbread

Name: Shortbread
Prep time: 15 min
Cook time: 25 min
Total time: 40 min
Yield: 2 servings
Cuisine: British
Ingredients: 250 g Unsalted Butter, softened to room temperature (use the best quality you can - Lurpak or a supermarket own-brand equivalent); 100 g Caster Sugar, plus extra for dusting; 250 g Plain Flour; 80 g Rice Flour, (gives the characteristic sandy texture - cornflour works equally well as a substitute); 0.25 tsp Fine Salt, (even with unsalted butter - a pinch of salt enhances the flavour considerably); 1 tsp Vanilla Extract, (optional - purists omit it; it adds a gentle warmth)

Shortbread is one of the great British biscuits - and one of the most deceptively simple bakes in existence. Three ingredients: butter, sugar, and flour. No eggs, no raising agents, no liquid. Just the ratio, the quality of the butter, and the bake. When it's made well, shortbread is extraordinary - pale golden, melt-in-the-mouth, with a delicate, sandy crumb that dissolves on the tongue and a rich, pure butter flavour that no amount of additional ingredients can improve.

Shortbread originates in Scotland, where it's been made in essentially the same form since the 16th century. The traditional Scottish recipe uses salted butter, plain flour, and caster sugar in a ratio of 1:2:3 - one part sugar, two parts butter, three parts flour. This recipe follows that classic ratio with one refinement: replacing a small portion of the plain flour with rice flour or cornflour, which gives the shortbread its characteristic sandy, crumbly texture rather than a firm, biscuit-like one.

Quality butter is the defining ingredient - use the best unsalted butter you can find, as the flavour is front and centre in every bite. This recipe makes a tray of shortbread fingers - the most traditional format - with rounds as an alternative. It keeps well for up to two weeks in an airtight tin, makes an excellent homemade gift, and is an essential Christmas bake. All ingredients are standard supermarket staples.

Ingredients

For the shortbread

250 g Unsalted Butter , softened to room temperature (use the best quality you can - Lurpak or a supermarket own-brand equivalent)
100 g Caster Sugar , plus extra for dusting
250 g Plain Flour
80 g Rice Flour , (gives the characteristic sandy texture - cornflour works equally well as a substitute)
0.25 tsp Fine Salt , (even with unsalted butter - a pinch of salt enhances the flavour considerably)
1 tsp Vanilla Extract , (optional - purists omit it; it adds a gentle warmth)

Method

In a large bowl, beat the softened butter and caster sugar together with a wooden spoon or electric hand whisk until just combined and pale - about 1–2 mins. Don't overbeat to a light, fluffy consistency as you would for a cake - shortbread should be mixed minimally to keep the texture short and crumbly rather than airy.

Tip: The butter must be properly softened - not melted, not cold. It should yield easily when pressed but still hold its shape. Cold butter won't cream smoothly and warm butter will make the dough greasy and difficult to handle.
Add the plain flour, rice flour, and salt (and vanilla if using) and mix with a wooden spoon until the dough just comes together into a smooth ball. Stop as soon as it forms - overmixing develops the gluten and makes the shortbread tough rather than melt-in-the-mouth.

Tip: The dough should come together cleanly without being sticky or crumbly. If it's slightly crumbly, use your hands to bring it together with a gentle kneading motion - the warmth of your hands will help. If it's sticky, refrigerate for 10 mins before proceeding.
Press the dough into a lined 20x20cm square baking tin, pushing it into the corners and levelling the surface as evenly as possible with the back of a spoon or the flat base of a glass. Alternatively, roll out on a lightly floured surface to about 1cm thickness and cut into rounds using a 6cm cutter.
Refrigerate for at least 30 mins - this firms the butter back up, prevents spreading during baking, and helps the shortbread hold its shape and crumble cleanly when cut.

Tip: Chilling the dough before baking is not optional for properly shaped shortbread. Warm dough spreads in the oven and produces soft, misshapen biscuits rather than the neat, defined fingers or rounds that characterise good shortbread.
Preheat your oven to 150°C fan / 170°C conventional / Gas Mark 3 - shortbread bakes low and slow to cook through fully without colouring.
For tray shortbread: prick the surface all over with a fork in a neat pattern - this is traditional and prevents air bubbles forming during baking. Score into 16 fingers with a sharp knife, cutting almost but not all the way through.
Bake for 22–25 mins until pale golden all over - not white, not brown. The shortbread should be an even, very light gold with no dark edges. It will still feel slightly soft when it comes out of the oven.

Tip: Shortbread is done when it is pale golden - not deeply coloured. A pale, even gold means the butter is cooked through and the shortbread will be crisp and crumbly once cool. Any darker and it becomes harder and less melt-in-the-mouth. If in doubt, err on the side of slightly underdone - it firms up considerably as it cools.
Remove from the oven and immediately dust lightly with caster sugar. Leave to cool in the tin for 10 mins, then cut along the scored lines with a sharp knife while still slightly warm - shortbread that has cooled completely is brittle and may crack if cut cold. Transfer to a wire rack to cool completely.

Air Fryer Method

Preheat the air fryer to 140°C for 3–5 mins. Line a small square tin or use a silicone shortbread mould that fits your basket.
Press the chilled dough into the tin, prick all over with a fork, and score into fingers as directed.
Cook for 18–22 mins until pale golden all over. Check from 16 mins - air fryers brown shortbread faster than a conventional oven so a lower temperature is essential. The shortbread should be an even, very pale gold with no dark edges.

Tip: Shortbread needs a lower air fryer temperature than most bakes - 140°C rather than the usual 150–160°C - because it needs to cook through slowly without colouring too quickly. Check frequently from 16 mins and remove as soon as it turns pale golden.

Alternatives & Variations

Reduce the butter to 200g and add 1 tbsp of cold water to bring the dough together - cuts the saturated fat noticeably while keeping the shortbread workable; the texture will be slightly less rich but still very good
Reduce the sugar to 75g - shortbread is not a particularly sweet biscuit to begin with; a smaller amount of sugar still produces a well-balanced result
Cut into smaller, thinner rounds rather than thick fingers - a natural portion control approach that keeps each piece at a lower calorie count

Swap the butter for a good quality vegan block butter - Naturli or Flora Plant both work well in shortbread at the same quantity. The texture is very similar to the dairy version, though the flavour is slightly less rich. All other ingredients are already plant-based.

Swap the plain flour for a gluten free plain flour blend - Doves Farm works well at the same quantity. The rice flour is already gluten free and actually improves the texture of gluten free shortbread as it's a natural component of the recipe. Add ¼ tsp of xanthan gum if it isn't already in the flour blend. The result is a very good gluten free shortbread - closer to the original than most gluten free biscuit recipes because the high fat and low flour content of shortbread is naturally forgiving of gluten free flour substitutions.

FAQs

Around 40 mins of active prep and baking, plus 30 mins of chilling time. It's a quick and straightforward bake with minimal equipment and virtually no washing up. One of the most efficient baking recipes on the site.

Rated Easy. The technique is minimal - the main things to get right are using properly softened butter, not overmixing the dough, chilling before baking, and pulling the shortbread from the oven while it's still pale golden rather than deeply coloured. All are straightforward with a little attention.

Most commonly because it was overbaked - shortbread should be pale golden, not brown. It can also become hard if the dough was overmixed, which develops the gluten and makes it tough, or if too much flour was used. Using rice flour or cornflour in place of some of the plain flour specifically prevents this by inhibiting gluten development.

Yes - it freezes very well both baked and unbaked. Freeze baked shortbread fingers in an airtight container for up to 3 months - defrost at room temperature for 1–2 hours. Freeze the raw dough as a log or pressed into the tin (before baking), wrapped tightly in cling film, for up to 3 months - bake from frozen adding 5–8 mins to the baking time.

Stored in an airtight tin at room temperature, shortbread keeps well for up to 2 weeks - one of the longest shelf lives of any baked good on the site. It actually improves over the first few days as the texture settles. Do not store in a plastic container as it makes the shortbread soft - a tin or glass container is essential.

Both give the characteristic sandy, crumbly, melt-in-the-mouth texture by reducing the proportion of gluten-forming plain flour in the recipe. Rice flour gives a slightly more neutral, delicate flavour and a finer crumb. Cornflour gives a marginally more tender, softer texture. Both are excellent - use whichever you have. If you have neither, all plain flour works but produces a slightly firmer, more biscuit-like shortbread.

Yes - shortbread works well in the air fryer with a slightly lower temperature than you might expect. Preheat to 140°C, press the chilled dough into a small lined tin that fits your basket, and cook for 18–22 mins until pale golden. Check from 16 mins - the air fryer browns it faster than a conventional oven. The result is very close to the oven version.
