The Crossover Concept
A new design concept merges two of the most recognisable brands in UK confectionery: M&S’s Colin the Caterpillar and Reese’s Peanut Butter Cups. The mockup shows the classic green M&S cake box, but updated with the unmistakable orange and yellow Reese’s logo. The product is pitched as a ‘Reese’s Peanut Butter Cup Colin the Caterpillar’, suggesting the standard chocolate sponge and shell would be paired with a peanut butter-flavoured buttercream filling.
This type of brand crossover has become a major feature of the snack market, but few combinations feel as direct as this one. Colin the Caterpillar is a cultural fixture, the default for office birthdays and children’s parties for over thirty years. Reese’s, an American import from Hershey, has established itself as the dominant peanut butter confectionery brand in British supermarkets. The logic of combining the two is immediate and seems to tap into an existing market demand for more elaborate, branded versions of established favourites.
The Colin Universe
The Colin the Caterpillar brand has expanded dramatically from its single-product origins in 1990. The core M&S range now encompasses a vast collection of spin-offs that take the character far beyond the cake aisle. There are miniature versions, including M&S Mini Colin the Caterpillar Cakes and M&S Colin the Caterpillar Softies, which are small sponge rolls.
The expansion into sugar confectionery is even more extensive. Shoppers can find multiple variations of gums and jellies, from M&S Colin the Caterpillar Cola Gums and Cherry Gums to Fruit Sours and Sour Stomps. Even the cake’s decorations have been spun out into their own product, M&S Colin the Caterpillar Speckles. The branding has also been applied to non-edible goods for children’s parties, with M&S Colin the Caterpillar Paper Plates and Party Cups available. This established pattern of diversification makes a flavour crossover seem like a plausible next step for the brand.
A Plausible Combination
While Colin is a quintessentially British product, Reese’s represents one of the most successful American food exports of the last two decades. The Peanut Butter Cup is its flagship, but the brand’s flavour profile is now a common sight in the ice cream, doughnut, and cake sections of most major retailers. For many shoppers, peanut butter as a sweet ingredient is now synonymous with the Reese’s brand.
The concept taps into this dual recognition. It places a familiar American flavour inside an iconic British format. The mockup’s caption, “Reese’s Peanut Butter Cup Colin the Caterpillar? Yes please!”, posted by design page UK Snack Attack, mirrors the simple, demand-led language common to fan pages and food news accounts. It presents the product not as a complex innovation, but as a straightforward and obvious combination that many would be surprised doesn’t already exist.
What the real range looks like
A Reese’s Peanut Butter Cup flavour would join an exceptionally broad M&S range. The current lineup includes the original M&S Colin the Caterpillar Cake, M&S Mini Colin the Caterpillar Cakes, and numerous sweets such as M&S Colin the Caterpillar Softies, Speckles, Cola Gums and Fruit Sours.
