Last year, I whimsically decided I wanted to try my hand at making bonfire toffee. A friend of mine sent me a bonfire toffee recipe, I got my ingredients and I prepared to create a bonfire treat that I would put into cute little bags and share with my family.
It was a disaster, a total unimitigated disaster. That sloppy brown liquid stayed in my fridge for days as I willed it to harden.
It didn't.
I threw it away.
My whimsical dreams dashed!

I might try again this year and if I do, this is the recipe I will be trying!
Ingredients
450g (2¼ cups) dark brown sugar
125ml (½ cup) water
115g (½ cup) unsalted butter
¼ tsp cream of tartar
125g (¼ cup) black treacle (molasses)
125g (¼ cup) golden syrup (light corn syrup)
Instructions
1. Prepare Your Equipment:
Line a tin: Use a 20cm x 20cm (8” x 8”) square tin or similar-sized baking tray, and line it with parchment paper. Grease the paper lightly to prevent sticking.
Test water: Fill a small bowl with cold water to test your toffee later if you don’t have a thermometer.
2. Melt the Ingredients:
Place the dark brown sugar, water, and butter into a large, heavy-based saucepan.
Stir gently over low heat until the sugar dissolves and the butter melts. Do not let it boil at this stage.
3. Add Treacle and Syrup:
Once the sugar and butter are melted, stir in the black treacle and golden syrup. Continue stirring until everything is well combined and smooth.
4. Boil the Mixture:
Turn up the heat and bring the mixture to a boil. Once it starts bubbling, reduce the heat slightly to maintain a steady boil without it boiling over.
Add the cream of tartar at this stage. This helps prevent sugar crystals from forming.
5. Cook to Hard Crack Stage:
Boil the mixture until it reaches the hard crack stage (about 140°C or 285°F). This can take around 15–20 minutes, but watch it carefully.
If you don’t have a thermometer, test the toffee by dropping a small spoonful into the bowl of cold water. It should harden instantly and snap when bent.
6. Pour and Set:
Once the toffee reaches the correct temperature, quickly but carefully pour it into your lined tin. Be cautious as the mixture will be extremely hot.
Leave the toffee to cool and set at room temperature. This can take about 1–2 hours.
7. Break into Pieces:
Once fully hardened, remove the toffee from the tin and break it into pieces by tapping it with a hammer or rolling pin.
Storage:
Store the toffee in an airtight container, and it will keep for up to 2 weeks.
Tips:
For added flavor, you can sprinkle a pinch of sea salt over the toffee before it sets, giving it a salted toffee twist.
Be cautious when handling hot sugar mixtures as they can cause burns. Use a heatproof spatula and wear oven mitts if necessary.
I'll let you know how it goes!
