M&S Colin the Caterpillar Meets Milkybar in a New Concept

A Major Brand Crossover

The Colin the Caterpillar cake is a pillar of British birthdays. So is Nestlé’s Milkybar. An image placing them together on one product was always going to get attention, and this concept shows exactly how that might look. The familiar green M&S box is adapted with Milkybar’s signature yellow and blue branding, promising a ‘milky dream’.

The cake itself appears in its classic log form, but with a crucial difference. Colin’s standard milk chocolate coating is gone. In its place is a thick layer of white chocolate, punctuated by the usual chocolate sprinkles and a white chocolate face. It’s a simple, effective premise, combining two of the most recognisable confectionery brands in the country into a single celebration cake.

The Colin Empire

Marks & Spencer has spent years building the Colin brand far beyond the original sponge roll. What started as a single cake is now an entire ecosystem of products, dominating a significant amount of shelf space. It is a huge portfolio.

The core cake is supported by M&S Mini Colin the Caterpillar Cakes for smaller occasions. The real expansion, however, is in confectionery. The current lineup includes Colin the Caterpillar Softies, Speckles, Cola Gums, Cherry Gums, Fruit Gums, Sour Stomps, and Fruit Sours. The branding even extends to non-edibles like Colin the Caterpillar Party Cups and Paper Plates. This consistent development has turned a simple cake into a legitimate FMCG platform, making new variations feel plausible.

A New Kind of Partnership

While M&S frequently releases new products under the Colin name, a co-branded effort with an external company like Nestlé would be a new strategy for the cake itself. Most of the innovation has focused on format-shifting the existing character into sweets or creating seasonal specials in-house.

A partnership with Milkybar would represent a different kind of move. It is less about extending the existing Colin flavour profile and more about importing a completely separate, and equally iconic, brand identity. This concept doesn’t just suggest a new flavour. It suggests a new commercial approach.

What the real range looks like

The core Colin the Caterpillar range includes the main cake, Mini Colin Cakes, and a wide array of confectionery like Softies, Speckles, Fruit Gums, and Sour Stomps. A Milkybar crossover would be a new direction for the cake, moving beyond simple flavour variations like those in the sweet range into a full brand partnership with an external confectioner.
