Biscuit vs Cookie: What's the Difference? A UK Guide

Quick answer

Biscuit vs cookie, or cookie vs biscuit: the difference between biscuit and cookie depends on where you are. In the UK, a cookie is a type of biscuit. Biscuits are usually small, flat, crisp and snappy, like a digestive or rich tea. Cookies are bigger, sweeter and softer or chewier, often with chocolate chips. In the US, "cookie" covers every sweet biscuit, and a biscuit is a soft, scone-like bread.

Ask a room of British people how a biscuit differs from a cookie and you'll get a lively debate over a cup of tea. Is a cookie just a big biscuit? Why do Americans call a scone a biscuit? The short version is that it depends on which side of the Atlantic you're standing, and in the UK it comes down to size, texture and what's in the dough.

In British English, "biscuit" is the big family name and "cookie" is one member of it. Wikipedia puts it neatly: in the UK, cookie usually refers to a single type of biscuit, the sweeter baked dough that typically contains chocolate chips or raisins. Even the UK government's food composition data files them that way. Chocolate chip cookies sit in CoFID under "Biscuits, cookies, chocolate chip".

Here's how the three things the words can mean usually compare:

  UK biscuit UK cookie US biscuit
What it is Small sweet bake A type of biscuit Quick bread
Texture Crisp, snappy Soft or chewy Soft, flaky
Size Small, thin Bigger, thicker Like a scone
Dough Firm, rolled Soft, scooped Rubbed-in, cut
Eaten With tea As a treat With a meal

Typical differences, based on Wikipedia's Biscuit, Cookie and Biscuit (bread) entries. Plenty of bakes blur the lines.

Think of a digestive, a rich tea, a custard cream or a ginger nut. They're small, firm and made to be dunked. Now picture a chocolate chip cookie from a bakery counter: wider, thicker, with a soft middle and chunks of chocolate. That's the everyday British line between the two, even if a shop-bought cookie can be just as crunchy as any biscuit.

Biscuits and cookies in the UK and the US

Most of the confusion comes from American English. In the US and parts of Canada, sweet biscuits are nearly always called cookies, and flat savoury ones are called crackers. So an American would happily call a digestive, a shortbread finger or a bourbon a cookie.

The word biscuit means something else entirely in the US. There it's a small, soft quick bread, raised with baking powder rather than yeast, that's served warm with butter, or with gravy at breakfast. It's much closer to a British scone than to anything in a biscuit tin.

  • In the UK: biscuit for most sweet bakes, cookie for the softer, chunkier kind, and crackers or "biscuits for cheese" for the savoury ones.
  • In the US: cookie for all sweet ones, cracker for the savoury ones, and biscuit for the scone-like bread.
  • In Scotland: Wikipedia notes that "cookie" can also mean a plain bun.

There's one more term worth knowing if you follow American recipes. Bakes made as a single slab in a tin and then cut into pieces are called bar cookies in the US and traybakes in the UK. Flapjacks, millionaire's shortbread and blondies all count.

Good to know

If an American recipe says "biscuits and gravy" or "buttermilk biscuits", it means a scone-like bread, not anything sweet. If it says "cookies", it could mean almost any sweet biscuit, crisp or chewy.

Dough, texture and baking

Words aside, there are real differences in how the two are usually made.

Biscuits

A classic British biscuit starts with a fairly firm dough that can be rolled out and cut, or pressed into shape. Shortbread is just butter, sugar and flour. Rich tea and digestives use less fat and sugar, which is why they're drier and snap cleanly. They're baked until they're crisp all the way through, so they keep well in a tin.

Cookies

Wikipedia describes a cookie as a sweet biscuit with a high sugar and fat content, made from a softer dough. That dough is usually scooped rather than rolled, so it spreads in the oven into a thicker, rounder shape. Cookies are often taken out while the centre still looks a little underdone, which keeps the middle soft and chewy as they cool. Chocolate chips, raisins, oats and nuts are the usual extras.

The stale test

During the Jaffa Cake tribunal, McVitie's famously argued that cakes go hard when they go stale, while biscuits go soft. By that test, a soft cookie that firms up as it goes stale is behaving more like a little cake than a crisp biscuit.

Where the words come from

The two words have very different roots, which helps explain why they ended up meaning different things.

  • Biscuit comes from the Old French bescuit, from the Latin bis ("twice") and coctus ("cooked"). Early biscuits were baked and then dried out in a slow oven, so they'd keep for months. Ship's biscuits fed sailors in the Royal Navy for centuries.
  • Cookie comes from the Dutch koekje, meaning "little cake". Wikipedia dates the American use, for a small, flat, sweet cake, to 1808. In Scotland the word was in use by 1701, but it meant a plain bun.

So in a sense the names still describe the bakes. A biscuit was made to be dry and crisp, and a cookie started life as a little cake. Italian biscotti, which are still baked twice, are the closest thing to the original meaning of biscuit.

Cake or biscuit? The Jaffa Cake case

In the UK, whether something is a cake or a biscuit isn't just a teatime argument. It matters for VAT. Most food is zero-rated, but HMRC's guidance on food and VAT says biscuits covered or partly covered in chocolate are standard-rated. Cakes are zero-rated.

That's why the Jaffa Cake ended up in a VAT tribunal in 1991. McVitie's argued that its Jaffa Cakes were cakes, and the tribunal agreed. According to Wikipedia's account of the case, the judge looked at things like the ingredients (a thin, cake-like batter rather than a thick biscuit dough), the fact that much of a Jaffa Cake is sponge, and how it behaves when it goes stale. McVitie's even brought a 12-inch Jaffa Cake to show that size makes no difference.

HMRC's examples still draw the line in some surprising places:

  • Zero-rated: chocolate chip biscuits where the chips are in the dough or pressed into the surface before baking, and bourbons, where the chocolate filling sits between two biscuits.
  • Standard-rated: biscuits wholly or partly coated in chocolate, chocolate-covered shortbread, and gingerbread men decorated with chocolate, unless it's no more than a couple of dots for eyes.

So, for VAT purposes at least, a chocolate chip cookie is treated like any other plain biscuit. It's the chocolate coating, not the word cookie, that changes things.

Scone vs biscuit: American biscuits vs British scones

If you've ever wondered what an American biscuit is called in the UK, the honest answer is that there's no exact match, but a plain scone is the closest. Both are quick breads made by rubbing fat into flour and raising the dough with baking powder, then cutting it into rounds.

Wikipedia's entry on the bread-style biscuit picks out the main differences:

  • Fat: biscuits always use a solid fat such as butter or shortening, while scones can be made with cream.
  • Egg: scone recipes usually include an egg; biscuit recipes often don't.
  • Texture: biscuits have more fat and less liquid, and they're folded to make flaky layers. Scones are crumblier and denser.
  • Flavour: biscuits tend to be plain and unsweetened, and they're served alongside savoury food. British scones are often lightly sweet and eaten with jam and cream.

If you're following a US recipe that serves biscuits with a stew or a cooked breakfast, a plain British scone made without sugar is a fair swap. Our keto scones recipe is a good place to start, and our guide to whether plain flour is the same as all-purpose flour explains the other American baking terms you'll come across.

Carbs in biscuits and cookies

Most standard biscuits and cookies are mainly flour and sugar, so they're high in carbs per 100g. Here's how some UK favourites compare in CoFID, the UK government's food composition dataset:

Per 100g Carbs Sugars
Rich tea type biscuits 75.4g 20.3g
Ginger nuts 75.3g 31.3g
Digestives, plain 65.6g 17.5g
Shortbread 62.2g 15.6g
Choc chip cookies, packet 60.0g 30.0g
Choc chip cookies, bakery 60.6g 40.5g
Plain scones, homemade 55.9g 5.4g

CoFID 2021 food codes 11-797 (biscuits, semi-sweet, including rich tea), 11-798 (ginger nuts), 11-799 (digestive, plain), 11-802 (shortbread), 11-815 (cookies, chocolate chip, standard), 11-816 (cookies, chocolate chip, American style, from in-store bakeries) and 11-958 (scones, plain, homemade). Carbohydrate excludes fibre, as on UK labels.

A few things stand out. The crisp, plain biscuits are actually the highest in carbs per 100g, because they're mostly flour with little fat or moisture. Cookies are a little lower in total carbs but higher in sugar than most of the biscuits, especially the big bakery-style ones. And an American-style biscuit's British cousin, the plain scone, has the least sugar of all, though it's still mostly starch.

As with any bake, size matters as much as the per-100g figure. A large bakery cookie can weigh several times as much as a rich tea, so if you're counting carbs, it's worth weighing one.

Lower-carb biscuits and cookies

To make lower-carb biscuits and cookies, the swaps are the same as for most keto baking: ground almonds instead of wheat flour, a sweetener that bakes like sugar, and chocolate sweetened with erythritol and stevia. The biscuit-or-cookie difference still comes down to the dough and the bake time.

  • For a crisp, snappy biscuit: our keto shortbread uses ground almonds, a little of our oat fibre and our Powdered Monk Fruit and Erythritol Sweetener, with 0.9g net carbs per finger. Our keto gingerbread biscuits are another good one for cutters.
  • For a soft, chewy cookie: our keto chocolate chip cookies use our Groovy Keto Cookie Mix with 80g butter, an egg and 40 to 50g of chocolate chips. The recipe makes 14 cookies at about 1.6g net carbs each. Our keto peanut butter cookies need just four ingredients and no flour.
  • For chunky cookies: chop our Dark Chocolate Buttons roughly and fold them through the dough for big pools of chocolate.

Key takeaways

  • In the UK, a cookie is a kind of biscuit. Biscuits are small and crisp; cookies are bigger, softer and chewier.
  • In the US, cookie means any sweet biscuit. An American biscuit is a soft quick bread, closest to a plain scone.
  • The words tell the story. Biscuit means "twice cooked"; cookie comes from the Dutch for "little cake".
  • Chocolate coating matters for VAT. Chocolate chips in the dough don't make a biscuit standard-rated; a chocolate coating does.

Frequently asked questions

Is a cookie a biscuit?

In the UK, yes. A cookie is usually treated as one type of biscuit: the bigger, sweeter, softer kind, often with chocolate chips or raisins. The UK's food composition data even lists chocolate chip cookies under biscuits. In the US it works the other way round, and every sweet biscuit is called a cookie.

Why do the British call cookies biscuits?

Biscuit is the older word in British English. It comes from the Latin for "twice cooked", because early biscuits were baked and then dried out so they'd keep. Cookie comes from the Dutch for "little cake" and took hold in American English from the early 1800s. Britain adopted it mainly for soft, chunky cookies.

Is an Oreo a cookie or a biscuit?

Both, depending on who you ask. Oreos are an American brand, so in the US they're cookies, like every sweet biscuit there. By the usual British test they're biscuits: small, crisp and sandwiched with a cream filling, much like a custard cream or a bourbon. Neither name is wrong; it's a matter of where you are.

What is an American biscuit called in the UK?

There's no exact British name, but the closest thing is a plain scone. An American biscuit is a soft quick bread raised with baking powder, made with butter or shortening and usually unsweetened. It's flakier than a scone and is often served with savoury food, such as gravy, rather than with jam and cream.

Is a Jaffa Cake a cake or a biscuit?

Legally, it's a cake. In 1991 a VAT tribunal ruled that Jaffa Cakes had enough of the characteristics of a cake to be zero-rated, as cakes are. The judge looked at the sponge base, the thin cake-like batter and the fact that Jaffa Cakes go hard when stale, as cakes do, rather than soft like biscuits.
