An Ambitious Crossover
The brand crossover is now a standard feature of the UK snack market, but some combinations feel more inevitable than others. This concept, pairing the M&S institution Colin the Caterpillar with the American peanut butter giant Reese’s, is one of them. It feels logical. The mockup presents a familiar format: the classic caterpillar cake box, updated with the distinctive orange and yellow of the Reese’s brand.
The product itself swaps out the standard chocolate buttercream for a peanut butter version. The usual chocolate button or Smartie-style decorations on Colin’s back are replaced with Reese’s Pieces. It’s a straightforward flavour substitution that builds on two hugely recognisable brands. The caption that accompanied the image was simple: “Reese’s peanut butter Colin the Caterpillar! An extremely peanut buttery dream cake. Would you try this?”
The Colin Franchise
Colin the Caterpillar is more than just a cake. It’s an entire product ecosystem. For years, M&S has expanded the line far beyond the original chocolate log centrepiece of a thousand office birthdays. The core range includes the classic full-size cake and the popular *M&S Mini Colin the Caterpillar Cakes* for individual servings.
But the brand’s reach is much wider. The confectionery aisle now holds a huge variety of spin-offs. There are *Colin the Caterpillar Softies*, *Speckles*, *Cola Gums*, *Fruit Gums*, *Cherry Gums*, *Sour Stomps*, and *Fruit Sours*. It has become a sweets brand in its own right, independent of its cake origins. This doesn’t even touch on the partyware, which includes branded *Party Cups* and *Paper Plates*. It’s a retail juggernaut. A truly massive range.
What the real range looks like
A Reese’s edition would join a vast collection of Colin the Caterpillar products, moving beyond the core M&S Colin the Caterpillar Cake to sit alongside a huge confectionery line that includes everything from Colin the Caterpillar Cola Gums and Fruit Sours to Softies and Speckles.

Frequently asked questions
- What is Colin the Caterpillar?
- Colin the Caterpillar is a chocolate sponge roll cake sold by Marks & Spencer. It’s decorated with a milk chocolate shell, sweets on its back, and a white chocolate face, and has been a popular choice for birthdays and celebrations in the UK since its launch in 1990.
- Has Colin the Caterpillar collaborated with other food brands before?
- Historically, major Colin the Caterpillar variations have been seasonal or event-based, like special Christmas or Halloween editions, rather than collaborations with external food brands. A partnership with a name like Reese’s would represent a significant new direction for the M&S cake franchise.
- Is the Reese’s Peanut Butter Colin the Caterpillar cake real?
- No. This product is a Snackfish — a mockup created by UK Snack Attack. It is a concept image and is not a real M&S product sold in any store.
