An Ambitious Crossover
Brand crossovers are now a standard feature of the UK snack market, but some partnerships feel more inevitable than others. This new design concept proposes a heavyweight collaboration: the M&S Colin the Caterpillar cake and the Cadbury Flake. The accompanying caption from its creator simply asks, “Crumbly Flake Colin the Caterpillar! Who’s craving this?”
The mockup shows the familiar green box, co-branded with the distinctive Cadbury Flake wordmark and purple colouring. On the cake itself, the traditional solid chocolate buttons and smartie-style shells have been replaced entirely. Instead, Colin’s back is covered with broken and crumbled sections of Flake. It’s a simple change, but one that fundamentally alters the texture and identity of the cake. The classic white chocolate face remains unchanged.
The Colin Franchise
The core Colin the Caterpillar cake is a fixed point in British culture, but the brand has expanded far beyond that single chocolate roll. The M&S range is now a sprawling franchise. There are, of course, the Mini Colin the Caterpillar Cakes for smaller parties, but the real diversification has happened in the confectionery aisle. The brand now extends to bags of Colin the Caterpillar Softies, Speckles, Cola Gums, and Fruit Gums.
That sweet range has its own subdivisions, too. Alongside the main variants are Sourtastic tubs, Sour Stomps, Cherry Gums, and Fruit Sours. There are even Colin-branded Party Cups and a Party Time mix. What’s notable about this expansion is that it has been entirely an in-house affair, using the Colin character and flavour profiles without incorporating third-party brands. A Cadbury edition would mark a significant shift in strategy, bringing another manufacturer’s flagship product directly onto the caterpillar itself.
A Structural Challenge
The appeal of a Flake is its precarious structure. Cadbury has spent decades marketing the bar on the basis that it is “the crumbliest, flakiest chocolate”. This property also makes it a difficult component to work with. Unlike a solid Dairy Milk button or a crunchy shell, a Flake is designed to disintegrate. Attaching it securely to the smooth, iced surface of a Colin cake would present a genuine manufacturing puzzle.
It would certainly be the messiest version of the cake to date. While the standard Colin can be sliced with relative neatness, a Flake-covered edition promises chaos. Every cut would send a shower of chocolate shards across the plate. This might be part of the appeal—a deliberate move away from the neatness of a party cake towards something more decadent and unrestrained.
What the real range looks like
The current M&S Colin the Caterpillar range is extensive. It includes the original M&S Colin the Caterpillar Cake and its smaller counterpart, the M&S Mini Colin the Caterpillar Cakes. The brand also covers a huge selection of sweets, including Softies, Speckles, Cola Gums, Fruit Gums, and multiple sour editions. A Flake variant would be a rare brand crossover for the core cake format.
