Bonfire Toffee Bark — A Nostalgic Twist on a British Classic
Bonfire Toffee has always been a family favourite in our house. Every autumn, the air smelled of smoke and fireworks. My parents and I would crowd around the stove. We would make a bubbling pot of golden toffee magic.
We’d hover with our frozen saucer. We tested for the perfect brittle stage. It was that thrilling moment when it hardened to a glossy snap. It was ready to shatter between your teeth.
The recipe wasn’t in a book. It was a handwritten recipe kept in an old, battered red purse. My mum kept the purse tucked in the back of a kitchen cupboard for safety. Not because it was filled with money, because it kept her treasure in one place. Pictures, clippings, and this bonfire toffee recipe.
Every November, the purse would come out. The ritual began with butter, sugar, and golden syrup melting. This created that unmistakable caramel scent that was Bonfire Night.
That handwritten recipe is long gone now, but the memories aren’t. So this year, I decided to bring it back — with a little modern twist: Bonfire Toffee Bark.

What Is Bonfire Toffee?
Bonfire toffee (also known as treacle toffee) is a traditional British sweet made from butter, sugar, and syrup. The mixture is boiled until it reaches the hard crack stage, around 150°C / 300°F. This gives it that glass-like snap and deep, smoky sweetness.
It’s everything nostalgic: the taste of cold nights, mittens, and fireworks. My Bonfire Toffee Bark takes that heritage. It adds a modern edge. It is topped with chocolate, pretzels, roasted nuts, and mini M&Ms.
Sweet, salty, crunchy, and mischievous.
How to Make Toffee (and Make Sure It Sets!)
Making homemade toffee can seem tricky, but it’s mostly patience and temperature control.
Here’s what helps every time:
• Use a sugar thermometer — you’re aiming for 150°C (hard crack).
• Once the sugar has dissolved, don’t stir too much. Crystallisation is the enemy.
• Watch the colour: rich amber = perfect.
• Add a pinch of bicarbonate of soda right at the end. It makes the toffee lighter. This also makes it easier to break.
Why Bonfire Toffee Is Still a British favourite
Bonfire toffee is one of those nostalgic British treats that never loses its charm. Its deep, smoky sweetness perfectly captures the taste of autumn. It has been part of Bonfire Night celebrations for generations. While some people remember treacle toffee from corner shops, others recall making it at home, waiting for that satisfying crack. You may enjoy it pure and simple. Alternatively, you can dress it up as a modern bark. In any form, bonfire toffee remains one of Britain’s most delicious little traditions.

Ingredients
Bonfire Toffee
- 250 g golden caster sugar

- 1 tbsp lyle’s black treacle optional, for deeper flavour
- 1 tsp white wine vinegar
- 1/2 tsp bicarbonate of soda

Instructions
Bonfire Toffee
- Prep the tray: Lightly grease the pan with butter, then line with baking paper and set aside.
- Melt: Add sugar, butter, syrup, treacle, and vinegar to a heavy-based pan. Heat gently and stir until smooth and combined.
- Boil: Turn up the heat a little and boil until it hits 150 °C / 300 °F (hard crack). Or until the toffee is crunchy (not chewy) when dropped in ice cold water.
- Bicarb magic: Remove from heat, add bicarbonate of soda, and stir quickly — it’ll foam.
