Cadbury makes two bars from a similarly crumbly, aerated chocolate recipe — but only one of them survives being carried around in a coat pocket without turning to rubble.
How a Twirl is actually made
Twirl launched in 1987 as two ridged, twisted milk chocolate fingers wrapped together in foil, each one coated more heavily than a Flake. The ridges aren't just decorative — they come from how the chocolate is twisted around itself as it sets, which also gives each finger enough structure to hold together when you bite into it. A single Twirl finger weighs in at around 21g, so the pack of two comes to roughly 43g.
Flake's accidental 1920s origin
Flake dates back to 1920, and the story goes that it was discovered almost by accident: a worker at Cadbury noticed that surplus chocolate running off the machinery used to fill mould bars folded itself into thin, ribbon-like waste. Someone at the factory realised the loosely folded ribbon looked distinctive enough to sell on its own, and Flake was born. It's been marketed for decades on its fragility rather than in spite of it — the 'crumbliest, flakiest chocolate in the world' slogan turned the bar's weakness into its whole identity, and it's the reason Flake, not Twirl, ends up pushed into soft-serve 99 cones.
Twirl vs Flake, side by side
- Structure — Twirl is two thick twisted fingers; Flake is one thin, loosely folded ribbon.
- Coating — Twirl has a noticeably thicker chocolate shell, which is what stops it collapsing.
- Launch date — Flake: 1920. Twirl: 1987.
- Typical use — Flake is the bar pushed into ice cream ('Mr Whippy' 99s); Twirl is eaten as a standalone bar.
- Mess factor — Flake showers crumbs on the first bite; Twirl generally doesn't.
Both sit within Cadbury's core chocolate range alongside the rest of the Cadbury lineup, if you want to compare them side by side.
Frequently asked questions
What's the difference between a Twirl and a Flake?
A Twirl is two twisted milk chocolate fingers with a thicker outer coating that holds its shape, while a Flake is a single loosely-folded ribbon of chocolate that's far more fragile and crumbles easily.
When was Cadbury Twirl launched?
Cadbury launched the Twirl in 1987, more than 65 years after the original Flake, as a sturdier two-finger alternative for anyone who found Flake too messy to eat on the go.
Why does Flake crumble so much more than Twirl?
Flake is made by folding a thin ribbon of chocolate loosely back on itself as it comes off the production line, which leaves lots of air pockets and weak points. Twirl's two fingers are thicker and coated more heavily, giving it far more structural strength.
