A Ferrero Rocher Colin the Caterpillar Cake Concept

Golden Hazelnut Praline

The Colin the Caterpillar cake is a fixed point in British culture. For over thirty years, the M&S chocolate roll cake has been non-negotiable at birthdays, office parties, and any event needing a guaranteed crowd-pleaser. Its core specifications are well-known: a chocolate sponge, buttercream filling, and a solid milk chocolate shell decorated with sweets.

A new design proposes a significant departure from this classic formula. The concept is a “Golden Hazelnut Praline” Colin the Caterpillar, a direct nod to the flavour profile of Ferrero Rocher. The mockup shows the familiar caterpillar shape, but with a gold-dusted finish and a topping of whole Ferrero Rocher chocolates. The packaging reflects the theme, swapping Colin’s usual bright green for a more sober brown and gold livery. The idea is clear. It merges a children’s party staple with a chocolate traditionally found on the after-dinner-tray.

The Colin Brand Universe

While a flavour crossover of this type would be new, expanding the Colin the Caterpillar range is standard practice for M&S. The brand is much bigger than the original cake. The core product line includes M&S Mini Colin the Caterpillar Cakes for individual portions and M&S Colin the Caterpillar Softies, which are small, fondant-covered sponge cakes.

The real expansion, however, is in confectionery. The character has been spun off into a huge range of sweets that have little to do with cake. You can buy M&S Colin the Caterpillar Fruit Gums, Cola Gums, Cherry Gums, and even sour variants like Fruit Sours and Sour Stomps. Alongside the sweets, there are also M&S Colin the Caterpillar Speckles, which are more like chocolate buttons. The brand has even moved into party supplies, with official M&S Colin the Caterpillar Paper Plates and Party Cups. It is a complete ecosystem. A special edition cake fits right in.

What the real range looks like

The actual M&S Colin the Caterpillar range is extensive, covering everything from the original cake and Mini Colin Cakes to a wide array of confectionery like Colin the Caterpillar Cola Gums, Fruit Sours, and Softies. This fictional Golden Hazelnut Praline edition would sit alongside the main cake as a limited-run flavour variant, a strategy M&S has used before for seasonal events.
