ABOUT
Jaffa Cakes didn’t just spark the cake-versus-biscuit debate - they blew it wide open. Instead of playing it safe, the campaign did the unthinkable: it backed the wrong side. When the UK’s beloved Biscuit Museum “classified” Jaffa Cakes as a biscuit, the internet lost its collective mind. Outrage bubbled, sides were taken, and McVitie’s waded in with a legal slap down, before dramatically resolving things by building the museum a shiny new Cake Wing. The result? Wall-to-wall coverage, live TV debates, a 17% sales boost, and Jaffa’s biggest month in three years. Not bad for a biscuit… sorry, cake. ????

BRIEF
Jaffa Cakes didn’t need us to start a debate.

They needed us to light a fire under one of the oldest arguments in marketing history.

Because the Cake vs. Biscuit row is one of Britain’s most familiar cultural conversations - endlessly referenced, rarely progressed. Reigniting it meant giving it new life, not repeating the same talking points the public had already heard.

The brief was to drive brand saliency and sales through earned media. Jaffa needed its mojo back, but in a way that felt fresh, unpredictable, and genuinely participatory. Not a campaign people observed, but one they felt compelled to take sides on.

There were clear rules: No celebrities. No surveys. No PR built to support ATL activity. This one had to hit different.

Our objective was to break from the conventions of previous debate-led campaigns and turn a well-worn argument into a live national story that unfolded in public, invited reaction, and ultimately drove people back in-store to buy Jaffa Cakes.

CREATIVE
To restart the debate, we did the one thing you’re not supposed to do – we agreed with the wrong side.

The campaign began with a quiet provocation: The UK’s No.1 (and only) biscuit museum appeared to have added a Jaffa Cake to its collection, officially categorising Jaffa as a biscuit.

The Biscuit Museum was small, independent, and widely loved, which made the claim feel credible, and the reaction was instant. Outrage spread across social feeds and comment sections, dragging the Cake VS Biscuit debate back into the national conversation.

That’s when McVitie’s intervened.

A cease-and-desist letter was issued to the museum, challenging the classification. Written in unmistakably playful Jaffa Cakes language, it felt legally real enough to matter and silly enough to be shared. The story escalated.

Then came the resolution.

Rather than shut the museum down, McVitie’s built them a new wing.

The Cake Wing no less. With a single exhibit inside: a Jaffa Cake, correctly categorised at last.

The story was seeded through a timed MailOnline exclusive, supported by deliberately low-fi assets to preserve authenticity. Each development was pitched as a genuine reaction as events unfolded, allowing press, social and broadcast to carry the narrative forward.

So, did we gaslight an entire nation into thinking the UK’s No1. biscuit museum added a Jaffa Cake to their collection, only for us to unleash the full force of the law upon them? ... Yes.

And do we regret it? ... Not one bit.


RESULTS AND EFFECTIVENESS
The campaign reignited national debate immediately. Within 48 hours, it generated 122 pieces of top tier coverage, including a MailOnline exclusive, followed by hits in The Guardian, London Standard, HuffPost, Independent and LADBible, alongside same-day broadcast features on ITV’s Lorraine and This Morning.

Momentum continued across the two-week period, with a total of 17 broadcast segments, including over three minutes of live debate across national daytime television.

The impact extended beyond attention into action with a 17% uplift in sales (in the world of mass market biscuits, that’s a huge number), delivering Jaffa Cakes’ best-performing month since July 2022, outperforming even the Christmas trading period.

Cultural impact followed. The Biscuit Museum received visit requests from around the world, and its co-owner Gary became recognisable in public during the campaign period, a small but telling indicator of the campaign’s reach beyond media metrics.
