A Three-Way Confectionery Crossover
A new design imagines a particularly decadent version of the UK’s most famous birthday cake. The mockup, captioned “Limited Edition Biscoff Colin the Caterpillar! Are you adding this Caramel & Biscuit dream to your trolley?”, proposes a Colin that merges three separate sweet concepts into one.
The box art depicts the familiar chocolate sponge roll, but with several additions. The face is a whole Lotus Biscoff biscuit, the body is drizzled with caramel, and the base appears to be layered with biscuit crumb. It’s an ambitious combination, pulling together the classic M&S cake, the caramelised spice of Biscoff, and the distinct caramel-and-chocolate layers of millionaire’s shortbread. These are three titans of the British treat aisle, rarely seen in a single product.
The Real Colin Range
The original M&S Colin the Caterpillar cake is part of a much larger, and stranger, product family. Over the years, the brand has expanded far beyond the signature chocolate log. The confectionery line is particularly diverse, including themed sweets that have very little to do with the cake itself. M&S currently sells Colin the Caterpillar Cola Gums, Cherry Gums, Fruit Sours, and Sour Stomps, alongside the more conventional Fruit Gums and chocolatey Speckles.
The cake format has also seen variation, but in a more conservative way. Mini Colin the Caterpillar Cakes offer a smaller portion size, but M&S has typically preferred to introduce new characters, like Connie the Caterpillar, rather than create heavily flavoured variants of Colin himself. This Biscoff Millionaire’s concept would represent a significant shift in that strategy, applying a trending, co-branded flavour directly to the original cake.
The Biscoff Takeover
Lotus Biscoff has become a go-to ingredient for brands looking to create a limited-edition buzz. Once known primarily as the small biscuit served with coffee, its flavour profile is now ubiquitous. The distinctive caramelised taste appears in spreads, ice creams, cheesecakes, and as a staple topping in dessert parlours across the country.
This makes its theoretical application to Colin the Caterpillar feel almost inevitable. It’s a flavour that consumers immediately understand and which has a proven track record of success in new formats. The mockup taps directly into this trend, proposing a collaboration that, while entirely fictional, seems perfectly plausible in the current UK snack market.
What the real range looks like
The real M&S Colin the Caterpillar range is extensive, including the main cake, Mini Cakes, and a wide variety of sweets like Cola Gums, Sour Stomps, and Fruit Sours. There are even party supplies such as paper plates. This fictional Biscoff Millionaire’s version would sit within the core cake line as a limited-edition flavour variant.
