Toffee vs Caramel: What's the Difference? A UK Guide

Quick answer

What is the difference between toffee and caramel? Toffee is sugar (or treacle) boiled with butter to the hard crack stage, around 150°C, so it sets hard and snaps. Caramel is sugar heated until it turns amber, around 170°C, and is usually finished with cream or butter, so it stays soft, chewy or pourable. Toffee is about texture; caramel is about colour and flavour.

Toffee and caramel sit side by side on sweet-shop shelves, in dessert names and on Bonfire Night tables, and the words are often swapped. So what is the difference between toffee and caramel? The short answer is how hot the sugar gets and what goes in with it. This toffee vs caramel guide explains how each one is made, why one snaps and the other oozes, how butterscotch and fudge fit in, and what bonfire toffee and toffee apples really are.

What is the difference between toffee and caramel?

Both start with sugar and heat, so they taste related. The difference comes down to three things: ingredients, cooking temperature and texture.

  • Ingredients. Wikipedia describes toffee as sugar or molasses caramelised with butter, and occasionally flour. Caramel can be nothing but sugar (a "dry" caramel) or sugar and water (a "wet" caramel), according to Hotel Chocolat, and it's often finished with cream.
  • Temperature. Toffee is boiled to the hard crack stage of 149 to 154°C. Caramel is about colour: Wikipedia says sugar caramelises when heated slowly to around 170°C, when its molecules break down into new compounds with the familiar amber colour and flavour.
  • Texture. Because toffee is boiled until almost all the water is gone, it cools hard and brittle. Caramel is usually loosened with cream or butter after colouring, so it ends up as a sauce, a chewy sweet or a soft filling.

In everyday British English the line is blurry. Wikipedia notes that soft caramel sweets are sometimes called toffee, and a wide range of confectionery is sold as toffee in the UK. So treat the table as the classic kitchen definitions, not a rule every label follows.

What is toffee?

Toffee is an English sweet. Wikipedia defines it as sugar or molasses caramelised with butter, and sometimes flour, heated until it reaches the hard crack stage of 149 to 154°C. Hotel Chocolat gives a working figure of around 155°C. At that point the syrup is almost pure sugar, which is why toffee sets into a glassy slab you break with a toffee hammer.

The word itself is fairly young. The Oxford English Dictionary, quoted by Wikipedia, dates the first printed use of "toffee" to 1825 and treats it as a variation of "taffy". Nuts or raisins are sometimes stirred in, and in the US "English toffee" is a very buttery version, often made with almonds and sometimes coated in chocolate, as in Heath bars.

Hard toffee vs chewy toffee

Classic toffee is hard, but plenty of UK toffees are chewy. Wikipedia says the American "English toffee" bears little resemblance to the wide range of confectionery sold as toffee in the UK today. Wikipedia's Candy making entry explains that lower cooking temperatures give softer sweets, which is why chewy toffees bend rather than snap. In practice they sit very close to caramel sweets.

What is caramel?

Caramel isn't one sweet but a family of ingredients made by heating sugars to high temperatures. Wikipedia lists its uses as a flavouring for puddings and desserts, a filling in chocolates and bars, a topping for ice cream and custard, and a colouring for drinks.

Hotel Chocolat explains that the sugar needs to reach around 170°C to caramelise, and that "wet" and "dry" describe the method rather than the finished texture. A dry caramel is sugar alone; a wet caramel starts with sugar and water. MasterClass adds that caramel is mainly made from white sugar, and Wikipedia notes that toffee and butterscotch use molasses or brown sugar instead.

Caramel sauce and caramel sweets

What you do after the sugar colours decides the result. Wikipedia describes caramel sauce as caramelised sugar mixed with cream, sometimes with butter or vanilla. Chewy caramel sweets are made from milk or cream, sugar, glucose, butter and vanilla, cooked to around 120°C, the firm ball stage. At that lower temperature the milk browns rather than the sugar, so these are sometimes called milk caramels.

Where salted caramel comes from

Salted caramel is a Breton idea. According to Wikipedia, salted butter caramels were sold in Brittany by 1946, and in 1977 the pastry chef Henri Le Roux created a salted butter caramel with crushed nuts in Quiberon, using Breton semi-salted butter. Top chefs took up the pairing around 2000, and it reached the mass market in 2008.

Sugar stages: why temperature matters

As a sugar syrup boils, water evaporates and the temperature rises. Each temperature matches a sugar concentration, so a sugar thermometer tells you how hard the finished sweet will be. Before thermometers were common, cooks dropped a little syrup into cold water and judged the lump: soft balls, firm balls, then threads that bend (soft crack) or snap (hard crack).

Stage Temp Example
Soft ball 112–116°C Fudge
Firm ball 118–120°C Soft caramels
Soft crack 132–143°C Butterscotch
Hard crack 146–154°C Toffee
Brown liquid About 170°C Caramel
Burnt About 177°C Bitter, too far

Take care with hot sugar

At hard crack, sugar is around 50°C hotter than boiling water. BBC Good Food warns that molten sugar can cause a lot of pain if it touches the skin. Use a heavy-bottomed pan and never leave it unattended, as BBC Good Food advises.

Butterscotch and fudge compared

Toffee and caramel have two close cousins, and the four are easiest to understand side by side.

Butterscotch

Wikipedia describes butterscotch as brown sugar and butter, sometimes with cream, vanilla and salt. It's like toffee, but boiled only to the soft crack stage, so it sets a little softer. The earliest recipes come from mid-19th-century Yorkshire and used treacle. S. Parkinson & Sons of Doncaster is often credited with inventing it, and the sweet became famous after Queen Victoria was given a tin in 1851. Today the word often just means the flavour of brown sugar and butter together.

Fudge

Fudge is sugar, butter and milk, heated to the soft ball stage, around 115°C according to Hotel Chocolat, and then beaten as it cools. Hotel Chocolat says beating gives it a creamy consistency that's thick, dense and easy to slice into chunks, rather than chewy or glassy. Modern fudge comes from 19th-century America, though Wikipedia notes that Cornish confectioners were making a clotted-cream version of Scottish tablet much earlier.

  Made with Stage Texture
Toffee Sugar, butter Hard crack Hard, snaps
Caramel Sugar, cream Amber Soft or runny
Butterscotch Brown sugar, butter Soft crack Firm, buttery
Fudge Sugar, butter, milk Soft ball Dense, crumbly

Bonfire toffee and toffee apples

With Bonfire Night on 5 November, this is toffee season in the UK.

What is bonfire toffee?

Bonfire toffee, also called treacle toffee, Plot toffee or Tom Trot, is a hard, brittle toffee linked to Halloween and Bonfire Night. Wikipedia says it tastes strongly of black treacle, is known as claggum in Scotland, and was popular in Yorkshire from about 1830 to 1900, when it was usually made at home. Recipes vary: BBC Good Food's version uses dark brown sugar, black treacle, golden syrup and cream of tartar, with no butter, boiled to 140°C. If you're curious about the key ingredient, our guide to black treacle vs molasses explains what it is.

Are toffee apples coated in toffee or caramel?

Strictly, it's a hard sugar coating closer to caramel than toffee. BBC Good Food's toffee apples are made from golden caster sugar, golden syrup, vinegar and water, boiled to 150°C, the hard crack stage, with no butter at all. BBC Good Food also says there's no key difference between toffee apples and candy apples: both use a caramel heated to hard crack, and "candy apple" is simply the North American name.

No thermometer?

BBC Good Food's test for hard crack is to drop a little of the hot syrup into a bowl of cold water. It should harden instantly and be brittle and easy to break. If you can still squash it, keep boiling.

Caramel flavours for low-carb baking

Traditional toffee and caramel are made almost entirely from sugar. Hotel Chocolat points out that caramel, fudge and toffee are all mostly sugar, with butter added in fudge and toffee. BBC Good Food lists 73g of carbohydrate, all of it sugars, for each of its homemade toffee apples, apple included. So if you're watching your carbs, a bag of toffees or a jug of caramel sauce doesn't really fit.

The flavour is easier to enjoy than the sweet itself. Our Salted Caramel Blondie Mix and Salted Caramel Mug Cake Mix get their caramel taste from natural flavouring with erythritol and stevia as sweeteners; there's no cooked sugar caramel in the ingredient lists. For the blondies you add 2 eggs and 130g butter and bake at 175°C for 20 to 25 minutes. For the mug cake you add 1 egg and 1 tablespoon of melted butter to a 50g sachet and microwave it for 1 minute. Our guide to what a blondie is explains how blondies differ from brownies.

For your own bakes, the Brown Erythritol & Stevia Blend is made from erythritol, stevia glycosides and caramel, and the product page says it swaps spoon for spoon with brown sugar. We haven't tested it in a boiled toffee or a hard crack recipe, so we can't say how it behaves at those temperatures; stick to the uses the product page suggests, such as cookies, flapjacks and crumbles.

Key takeaways

  • Toffee is boiled hard. Sugar or treacle and butter go to hard crack, about 150°C, so it snaps.
  • Caramel is cooked to colour. Sugar turns amber at about 170°C, then cream or butter softens it.
  • Butterscotch and fudge sit between. Butterscotch stops at soft crack; fudge stops at soft ball and is beaten.
  • UK labels blur the words. Chewy toffees and toffee apples are often closer to caramel.

Frequently asked questions

Is toffee just caramel with butter?

Not quite. Both start by cooking sugar, but toffee is sugar or treacle boiled with butter to the hard crack stage, around 150°C, so it sets hard. Caramel is cooked until the sugar turns amber, around 170°C, then usually softened with cream or butter, so it stays chewy or pourable rather than brittle.

Which is harder, toffee or caramel?

Classic toffee is harder. It's boiled to the hard crack stage, 146 to 154°C, when the syrup is almost pure sugar, so it cools glassy and snaps. Caramel sauce and chewy caramels have cream or butter added after colouring, which keeps them soft. Many chewy toffees sold in the UK sit closer to caramel.

What is the difference between caramel and butterscotch?

Caramel is usually made with white sugar cooked until amber, then finished with cream. Butterscotch is made with brown sugar and butter, and as a sweet it's boiled to the soft crack stage. The word butterscotch is also used for the flavour of brown sugar and butter together, as in butterscotch sauce.

What is the difference between toffee and fudge?

Fudge is sugar, butter and milk heated only to the soft ball stage, around 115°C, then beaten as it cools so it turns thick, creamy and sliceable. Toffee is sugar or treacle and butter boiled much hotter, to hard crack, around 150°C, so it sets hard and brittle instead of soft and crumbly.

What is treacle toffee?

Treacle toffee, also called bonfire toffee or Plot toffee, is a hard, brittle British toffee made with black treacle and sugar, often with butter, and eaten around Halloween and Bonfire Night. It tastes strongly of treacle and is called claggum in Scotland. BBC Good Food's recipe boils dark brown sugar, treacle and golden syrup to 140°C.
