A Banoffee Pie Colin the Caterpillar Sponge Cake Mockup

A Classic Dessert Mashup

The Colin the Caterpillar range is a British institution, but it rarely ventures into classic dessert territory. This concept changes that, proposing a Banoffee Pie edition of the famous cake. The mockup’s packaging, which carries the caption “Imagine this for dessert,” shows a sponge cake filled with banana and caramel layers, a significant departure from the standard chocolate-covered log.

Banoffee is a logical, if ambitious, step for a mainstream cake line. The combination of banana, cream, and toffee is a staple of pub dessert menus and home baking, but it requires fresh ingredients that present a short shelf life. This design imagines it as a pre-packaged sponge, which would be a first for the Colin brand’s cake offerings. It’s a familiar flavour profile presented in an entirely new format for the M&S mascot.

Beyond the Birthday Cake

Colin the Caterpillar is no longer just a single cake. The brand has expanded into a sprawling franchise of confectionery and party supplies that occupies significant shelf space in M&S food halls. The original chocolate log has been joined by Mini Colin the Caterpillar Cakes, but the real growth has been in sweets.

The current range includes M&S Colin the Caterpillar Softies, Fruit Gums, and even flavour-specific packs like Cherry Gums and Cola Gums. For those after a different texture, there are Sour Stomps and Fruit Sours. The branding even extends to non-edibles like Colin the Caterpillar Paper Plates and Party Cups. The caterpillar’s face is now one of the most versatile pieces of food IP in the UK.

A Change in Format

Perhaps the most notable thing about this concept isn’t the flavour, but the physical form. Colin is, by definition, a log. A long, solid chocolate cake with a hard chocolate shell. This Banoffee Pie version is presented as a rectangular sponge cake, possibly a Swiss roll, sold in a box showing a single slice.

This would place it in a different category entirely. It’s not a celebration cake in the same way as the original, but a dessert option for a smaller group. It moves Colin away from the children’s party table and into the territory of after-dinner treats, competing with trifles and cheesecakes. While the brand has diversified into sweets, this would be the first time the core product—cake—has been reimagined so completely.

What the real range looks like

A Banoffee Pie Colin would be an entirely new cake format, sitting alongside the classic M&S Colin the Caterpillar Cake and the M&S Mini Colin the Caterpillar Cakes. The flavour innovation would align it with the wider brand, which includes a huge variety of confectionery such as Colin the Caterpillar Softies, Cola Gums, and Sour Stomps.
