M&S Oreo Colin the Caterpillar Cake Concept Appears

A Cookies & Cream Makeover

Colin the Caterpillar is an institution. For more than three decades, the M&S chocolate log has been the default choice for office birthdays, family parties, and any occasion requiring a guaranteed crowd-pleaser. He is a British icon.

A new design doing the rounds online proposes a significant departure from the classic formula. The mockup merges Colin with another global giant: Oreo. Visually, it’s a dramatic change. The familiar milk chocolate shell is gone, replaced with a thick, white, cookies-and-cream style buttercream. The caterpillar’s back is decorated not with Smarties-style sweets, but with rough-chopped pieces of dark Oreo biscuit.

The Caterpillar Ecosystem

A major flavour extension like this might seem unlikely, but the Colin brand has expanded far beyond its original format. M&S has spent years building Colin into a complete commercial ecosystem. The character is no longer just a cake. He is a platform.

This expansion has happened in two distinct directions. First, the cake format itself has been iterated on, giving us the shareable M&S Mini Colin the Caterpillar Cakes and the smaller, snack-sized Colin the Caterpillar Softies. These are logical, safe variations on a theme.

The second, more ambitious direction is confectionery. Colin now fronts a surprisingly broad range of sweets, often borrowing formats from other market leaders. These sweets occupy a lot of shelf space.

What the real range looks like

The current M&S confectionery line includes Colin the Caterpillar Speckles, Cola Gums, Fruit Gums, Cherry Gums, Sour Stomps, and Fruit Sours. The brand even extends to non-edibles like Colin the Caterpillar Party Cups and Paper Plates, part of the ‘Party Time’ range. Within this extensive catalogue, a special edition Oreo cake doesn’t seem quite so far-fetched. It would sit as a major flavour event alongside the core product.
