Jaffa Cake Colin the Caterpillar: The M&S Crossover

Two UK Icons Combined

Colin the Caterpillar is an M&S institution. McVitie’s Jaffa Cakes are a national staple. A new mockup brings them together, proposing a sponge roll that swaps out Colin’s usual buttercream for a layer of orange jelly and his milk chocolate shell for the dark chocolate of a Jaffa Cake.

The crossover is a logical one, at least on paper. Both are fundamentally sponge, chocolate and a sweet filling. The execution, however, would be a notable departure for M&S. Colin has remained remarkably consistent in his core cake format since launching in 1990. While his appearance has changed slightly over three decades, the fundamental milk chocolate and buttercream recipe has not.

The Colin the Caterpillar Range

The branding around Colin has expanded into a huge territory for M&S. The character now fronts an enormous range of spin-off products, though very few are actual cake variants. The expansion has been almost entirely into the confectionery aisle. This is a very specific strategy.

The current line-up includes M&S Colin the Caterpillar Softies, Speckles, Cola Gums, Sourtastic gums, Fruit Gums, Sour Stomps, and Cherry Gums. There are also Mini Colin the Caterpillar Cakes, but these are a format change, not a flavour one. A Jaffa Cake edition would be the first major flavour crossover for the primary cake product, placing it in a category of one. The brand’s focus is clearly on sweets, not on creating a line of different-flavoured large cakes.

What the real range looks like

The core Colin the Caterpillar range from M&S is vast, but it leans heavily into confectionery rather than cake variations. Alongside the original and Mini cakes, the line includes Softies, Speckles, Cola Gums, Sourtastic Gums, Fruit Gums, Sour Stomps and Cherry Gums. A Jaffa Cake version would be a rare flavour extension for the main cake format itself, a territory M&S seldom explores.

Frequently asked questions

What flavour is a Jaffa Cake Colin the Caterpillar?
The concept proposes a chocolate sponge roll with an orange-flavoured filling and a plain chocolate coating, directly mimicking the ‘full moon, half moon, total eclipse’ profile of a classic McVitie’s Jaffa Cake.
Does M&S make other Colin the Caterpillar cake flavours?
No. While there are seasonal and special editions of Colin, these are typically decorative changes. The core flavour profile of the main cake remains the same. The brand’s expansion is focused on sweets and mini versions, not flavour variants of the large cake.
Is the McVitie’s Jaffa Cake Colin real?
No, this product is not real. The image is a Snackfish — a fictional concept designed by the online creative page UK Snack Attack. It is a mockup and is not available for purchase from M&S or any other retailer.
