Cadbury Twirl Launches 'Golden Dipped' With an 18-Carat Gold Bar Hidden in Hatton Garden
TL;DR: Cadbury Twirl and Ogilvy are launching Twirl Golden Dipped with a one-day Hatton Garden jeweller takeover and two real 18-carat gold-plated Twirl bars given away to lucky fans.
A Value Product, a Golden Idea
Cadbury Twirl, owned by Mondelēz and working with Ogilvy, rolled its limited-edition Twirl Golden Dipped out to major retailers from 16 September 2026. The bar pairs Cadbury milk chocolate with a caramelised white-chocolate layer.
The launch's centrepiece is a one-day 'Hatton Golden' activation at Solitaire Jewellers, 8 Hatton Garden, on 24 September, where a bespoke 18-carat gold-plated Twirl will sit on purple velvet in the window.
Turning a Line Extension Into Earned Media
Two 18-carat gold-plated Twirl bars have been made. One is hidden among free samples at the jeweller for a random winner; the other is given away through a Cadbury social-media prize draw. Twirl brand manager Josep Sallares called it 'our most indulgent Twirl launch to date.'
It is a neat piece of value engineering: a modestly priced FMCG product dramatised by a genuinely valuable prize and a location — London's jewellery quarter — that makes the golden idea literal.
Why the Format Works
The stunt is cheap relative to its shareability. A single hero object (the gold bar), a single evocative location and a random-winner mechanic give both press and social a reason to talk — without the cost of a national media blitz.
It also gives retailers a story to merchandise around, extending the launch from a shelf listing into a moment.
Marketing Minute's Take
This is the reusable template: take a small product truth (a golden new layer), find the most literal possible expression of it, and attach one high-value, low-volume prize. The maths favours the brand — a couple of gold-plated bars buy more attention than the same spend in paid reach. Steal the structure, not the chocolate.
Quick FAQ
What is Cadbury Twirl Golden Dipped?
A limited-edition Twirl that pairs Cadbury milk chocolate with a caramelised white-chocolate layer, rolled out to major UK retailers from 16 September 2026 and launched via Ogilvy.
How can you win the gold Twirl bar?
Cadbury made two 18-carat gold-plated Twirl bars — one hidden among free samples at a Hatton Garden jeweller activation on 24 September, and one given away via a Cadbury social-media prize draw.
Why is the campaign effective?
It turns a low-cost line extension into earned media using a single high-value prize and an evocative location, delivering shareability far above what the same spend would buy in paid reach.
This is textbook value engineering. Two gold-plated bars and a jeweller's window will out-earn a chunk of paid media, because the idea is literal, ownable and easy to share. The craft is in the restraint — one hero object, one location, one mechanic. Most brands overspend and under-focus; Twirl did the opposite. — Daniel Nikolla, Founder of Merx Marketing
The takeaway: one high-value prize plus the most literal expression of a product truth can out-earn paid reach — focus beats budget in stunt marketing.
