I have another sweet treat to share with you this week, and one that is perfect for bonfire night. That’s right I have a yummy bonfire toffee recipe for you to have a try.
Bonfire toffee or treacle toffee is something that reminds me of the late stages of autumn to early stages of winter, more specifically bonfire night or Guy Fawkes night. It is a hard-boiled sweet treat with a smoky warming taste to it. A slightly acquired taste, but one that is delicious nonetheless.
I can remember watching the large roaring bonfires and firework displays when I was younger, whilst enjoying this sweet treat.
This sweet has several other names as well; tom trot and plot toffee. I haven’t heard these before, so it looks like every day is a school day!

Bonfire Toffee
Now, bonfire toffee consists of several ingredients and has very high sugar content. One of the ingredients wasn’t originally used as part of baking/sweet making, however. Black treacle gives the bonfire toffee recipe a bitter-sweet liquorice taste, as well as the deep amber colour. It is similar to molasses, however is slightly sweeter. This was originally used as a medicine for a variety of ailments. It later then began being used in more sweet treats like this treacle toffee and bonfire toffee recipe.
Similar to cinder toffee, this is a mixture of sugar that is heated to a very high temperature. To get the sugar to set into the hard-boiled consistency, the sugar has to reach a high of 150°C/300°F. Therefore, if recreating this bonfire toffee recipe, then I would advise keeping small children at a distance, as well as using a fairly high sided saucepan. We don’t want any accidents happening whilst making this!

So if this has piqued your interest, then let’s get sweet making!
Bonfire Toffee Recipe
I am making this bonfire toffee as one large slab and breaking it into pieces, however, you can make it to fit any shape that you like. So, if you fancy bonfire toffee lollipops, then you can use this recipe to make them too! You just have to make sure you have the correct type of mould, ideally made with silicone. The toffee won’t stick to the silicone but will weld itself to metal. If all you have is a metal baking tin, make sure it is completely covered and greased to the max with greaseproof paper.

What You Need:
To make the bonfire toffee, you will need the following ingredients and items. Some items on this list are affiliate links and are marked with an asterisk (*).
- 450g Dark Brown Sugar
- 125g Golden Syrup
- 100g Black Treacle
- 125ml Water
- 25g Butter
- ¼ tsp Cream of Tartar
Items:
- Heavy Based Saucepan
- Silicone Baking Mould (Square)*
- Silicone Spatula*
- Food/Sugar Thermometer*

Step 1 – Prepare Baking Mould
I am using a square silicone mould for my toffee to set in, however you can use whichever mould you like. If you have a metal baking tin, then make sure you fully grease and cover it completely greaseproof paper/baking paper. You don’t want any of the metal exposed, as the toffee will adhere to this and will be near on impossible to remove.
Even though I used silicone, I placed butter in to provide extra grease for easier removal.
Also place the mould on a heatproof surface as well, as the toffee will be VERY hot when first poured into the mould.

Step 2 – Heat Ingredients
In the large heavy-based saucepan, place in all of the ingredients. Give the mixture a gentle stir and then begin heating on medium heat. Keep heating until all of the ingredients have dissolved together. The sweet liquid should have turned smooth and dark. You can gently stir during this.

Step 3 – Turn up the Heat
When the ingredients have dissolved, the heat can be cranked up to bring the liquid to a rolling boil. This is where your thermometer comes in because we need the toffee to reach the ‘hard crack’ stage for it to form into the hard-boiled sweet. Stir frequently during this, but be careful as the sugar syrup will begin to bubble and come up the sides of the pan. Keep heating until the toffee reaches 150°C/300°F. This is when the toffee reaches the hard-crack stage and can take around 10-15minutes.
As the sugar is getting to a high temperature and can begin to boil up the pan, it is best not to leave this unattended. You want to make sure you keep an eye on the sugar, as you also don’t want it to begin to burn.

Step 4 – Pour into Mould
Once the toffee reaches the temperature, remove it from the heat. Immediately pour it into the mould, scraping as much out of the pan as possible. You will notice that as the majority of the toffee comes out of the pan, the edges will begin to cool and be more difficult to scrape out. There may also be some sugar strands/webs forming as well.
Allow to cool and completely set in the mould. This may take a few hours.

Step 5 – Break into Pieces
When the treacle toffee is completely set, it is time to break it into pieces and remove it from the mould. To do this you will need a toffee hammer, or as I like to use a rolling pin.
Keeping the toffee in the mould, place a piece of greaseproof paper over the top. This will help keep all of the toffee pieces in the mould rather than splintering everywhere. Then grab your rolling pin or toffee hammer and begin hitting the toffee.
The toffee should break into pieces. Keep hitting it until you get the desired size chunks.

The bonfire toffee can be stored in an airtight container, just place greaseproof paper as layers. This will reduce the toffee sticking together. The toffee should last for at least a week or two in the airtight container. You may find the longer it is left, the stickier and softer it becomes…still delicious though!
And that is an easy bonfire toffee recipe for you to make and enjoy this bonfire night!

Bonfire Toffee
Equipment
- Heavy-Based Saucepan
- Silicone Mould
- Silicone Spatula
- Sugar/Food Thermometer
- Greaseproof paper
- Toffee Hammer or Rolling Pin
Ingredients
- 450 g Dark Brown Sugar
- 125 g Golden Syrup
- 100 g Black Treacle
- 125 ml Water
- 25 g Butter Plus extra for greasing
- 1/4 tsp Cream of Tartar
Instructions
- Prepare the mould for the toffee by greasing and lining it with greaseproof paper. If using a silicone mould, use butter for extra grease/easy release. Place the mould onto a heat proof surface.
- Place all of the ingredients into a heavy-based saucepan. Begin heating over medium heat. Continue heating until all of the ingredients have dissolved. The liquid should turn dark and smooth.
- Crank up the heat to a medium-high and bring the sugar liquid to a rolling boil. You can stir the mixture at this point frequently until it reaches 150°c/300°f or the hard-crack stage. This can take 10-15 minutes.
- Once the desired temperature is reached, remove from the heat immediatley and pour into the waiting mould. Allow the toffee to cool and set, this can take a few hours.
- When set, keep the toffee in the mould. Then, place over a layer of greaseproof paper and hit with a toffee hammer or rolling pin. This will break the toffee into pieces. The bonfire toffee is then ready to be enjoyed!
- Tip: Keep the bonfire toffee in an airtight container, placing greaseproof paper between the layers to stop the toffee from sticking together. The toffee should last for up to 2 weeks in an airtight container. You may find the toffee goes slightly soft and sticky the older it is, but it is still edible!




Gosh this takes me back! My grandmother used to make this and she had a special toffee hammer to break it with. Living in Italy I can’t get the black treacle or golden syrup – but perhaps my fillings are relieved LOL.
I wish we had a special toffee hammer, but then I would be making this all the time just to use it haha. Oh, what a shame, I wonder if there are any alternatives. Like you say, it might be best for the teeth!

I have not heard of this kind of toffee before but it looks and sounds delicious! Have a wonderful bonfire night and thanks for sharing this recipe.
Oh, it is delicious and has a slight liquorice/smokey taste to it (I think it does anyway). Glad you liked it!
Have a lovely week!

I remember having this as a child too! I have to be honest, the slightly smoky flavour didn’t appeal back then but now I’m (so much) older, my tastes have changed. Might have to give this a try and see what Flora thinks too 🙂 Thank you for the recipe, and the safety tips!
It is amazing how your tastes change as you get older. Although, I have always sort of liked bonfire toffee!
Hope you like it, if you do give it a go. If not, I bet there will be friends and family who would love a sweet treat gift!
Thanks for commenting Lisa!

It is definitely a yummy sweet treat! I hope you like it if you do have a go at making it.

I have never had nor heard of this type of toffee, but I love that it is darker and richer than cinder toffee, being licorice-like tasting! When you said that it softens a bit with age, I imagined making this and leaving it a while so I can come back to when it has become a bit stickier. That texture sounds just about perfect for me! 🙂
It is definitely so much richer than cinder toffee, and ore hard. It does get sticky the longer it is left, so hopefully, you will like it if you do have a go at making this. You will have to let me know what you think if you do (whether good or bad!).

Glad you like it. I think it might be more the northern UK treat, but I may be wrong! It would go wonderful with a slice of Parkin too!
