How to Make Treacle Toffee

Another Bonfire Night How To – Treacle Toffee this time

What I can’t tell you is how to eat it without ending up at the dentist!


450g demerara sugar

450g black treacle

150g butter

Makes: Approx 70 pieces – feel free to halve the quantities for a smaller batch but you’ll also need a smaller tin to set it in.

Very easy to make, just like the honeycomb.  Line an 8″ square tray (or similar) with baking paper.

Chuck all the ingredients in a pan and heat it over a gentle heat until the sugar melts stirring occasionally.

No stirring now, turn up the heat a little and bring the mixture to the boil.

A sugar thermometer is super handy if you’re bothered about how hard you want it to set.

For a soft set ie you can still just snip it with scissors (kinder on the fillings!) you want to heat the mixture to 120c.

For a firm set  ie. smash it up with a hammer (it still melts to chewy treacle toffee in your mouth) you want to heat it to 130c.

This mixture comes up to temperature very quickly – 120c in 4 minutes from boiling and 130c in 5 minutes.  Set a timer if you’re not using a thermometer.

Take it off the heat and pour it into the prepared tin.  As always please please don’t burn yourselves.

Now let it set,  keep an eye on it though we still need to break it up into pieces.

After about 1 hour for the firmer set toffee test it by poking it carefully with a finger, if the imprint remains indented you’re good to go, it may take a little longer and takes a couple more hours for the softer set to be ready to chop up.

Lift the paper out of the tin and fold it out.

Take a long knife and grease the blade with a little sunflower or vegetable oil.

Mark the slab into strips pressing right down to the paper at the base, you’ll need to grease the blade after each strip.

Now mark it in the same way widthways.

The slab will still be holding together.

Using the knife, break away one strip at a time.  Then split it into the individual chunks.  The toffee is still cooling all the while you’re marking and shaping the pieces so you may find you can simply snap it into the individual pieces by hand.

For the softer set toffee you’ll need plenty plenty of greasing and after marking its easier to use scissors to break up the individual pieces.

So disaster has struck and your toffee is too hard to mark out and cut into pieces – you have two options.  Shatter it up into irregular pieces or put the whole lot back into a pan, melt it on a gentle heat until its all liquid again and pour it back into the lined tin and go again.

If the toffee is too soft and will not set up, heat it up again in the pan, boil it for two minutes and on you go!

Treacle toffee travels best when individually wrapped but it is time consuming cutting up bits of non-stick baking paper or waxed paper and wrapping them by hand,  after searching online I couldn’t find anywhere selling individual waxed paper squares – I swear I’ve seen them in a shop but can’t for the life of me remember where it was.

It keeps well if unwrapped in an air tight container between layers of baking paper.

  6. Sarah says:

    Honestly I have made treacle toffee several times but have never even THOUGHT of cutting it up like that. Would make the wounds made by sharp edges a thing of the past. lol

  7. Lorna says:

    You are a *
    I’ve already made Bonfire Toffee, successfully, for the very first time, however I wanted to make chewy Treacle Toffee…. Even ‘tho I’m great at tablet, jams and pickles, chewy toffee seemed somewhat daunting.
    Googled. Came accross you and The Pink Whisk.
    Pictures! Sensible, non-faffing, practical to a home cook instruction!
    Thank you, thank you, thank you…. it’s no longer a scary prospect.
    First batch is cooling as I type.
    You’re now a shortcut on my mobile and I am off to investigate what else I can challenge myself with.

    Does the butter have to be unsalted or salted please

  9. Roger Goodier says:

    Well I’m a 74 year old man and this was easy ,thanks for the chewy recipe,by the way I did it in the microwave .plastic bowl and wooden spoon and used a thermometer to obtain the setting at 120’c

  10. Bernadette says:

    I’ve never made toffee before but because I had nearly a whole tin of treacle left after making my christmas cake I thought I’d try it………. It’s gorgeous, treacle toffee is my favourite and now I can make it . Your instructions were easy to follow and it tastes great. I don’t have a thermometer so just timed it, it’s a bit softer than I wanted but I’m going to get one so next time it should be perfect.
    Thanks x

      If you’ve no sugar thermometer use a cup of cold water and drop a little of your mixture into the water, pour the water away and try the toffee, if it’s not to your liking boil some more then test again.

  11. Thirza says:

    Mmmmm. Must give this a try! Perhaps you could take your bakingpaper to a copy shop and ask to use their big guillotine to cut a lot of paper to sweet size? We have got one at work, so will got that route probably!

  12. Suzanne says:

    Hi Ruth,

    Thanks for the recipe which is cooling as I type this. Looking forward to eating it very much! I made the soft set using your timing method. Do you know if condensed milk could be added to make the flavour slightly milder for children? Love the practical no-nonsense recipes. Keep up the good work!

  13. Miriam says:

    I’m an English gal living in the US and I just made these using molasses and dark brown sugar.
    Worked perfectly!
    Great recipe and the timing were very accurate as I do not own a candy thermometer.
    Don’t make the same mistake as me and use wax paper to line your tin! Baking parchment for lining and the wax paper was perfect for wrapping.
    I just went to a Bonfire and these went down a treat with the ex-pats!

  14. Sandra says:

    what do you do with left over treacle, make your delicious toffee recipe ! Thank you! It’s delicious and have added some nuts !

  15. Jess says:

    Looks great!! Can’t wait to try it this weekend 😀

  16. Katy says:

    I’m glad I googled recipes with molasses.
    I adore treacle toffee so I’m about to try your recipe.
    You’ve made it really easy to follow, especially the timings as I don’t have a sugar thermometer as I have always used the saucer of cold water to test for hardness.
    Thank you, thank you, thank you.

  17. Gail says:

    Hi I made his for the first time and burnt my pan lol but the second batch was gorgeous thank you xx

  18. Caron says:

    Hi can u pls tell me why my treacle toffee is sticking to the greaseproof paper, and what shall i do to fix it ?

    • Greaseproof paper will stick to practically anything – you need a non-stick baking paper. To help get the dratted greaseproof off you need to steam it off which isn’t easy to do. Try a little boiling water between the tin used to set it in and the paper, once its very lightly damp the paper should peel more easily – hope that helps and you have some success x

  19. Rob Watkins says:

    Thankyou very much for this recipe 😊 I’m now waiting for the cooling process to tell a tail. However, I did notice when I poured the toffee into the try, that there was a trace of the sugar not having melted, and yet it (I thought) had cooked and boiled long enough? Any ideas as to why this may have happened? X

    • It sounds like the mixture might have started to crystallise at the edges of the pan, to stop it happening as the mixture comes to the boil brush down the sides of the pan with a pastry brush dipped in water to get all the sugar crystals back down into the mixture xx
