A New Format for Buttercream
Marks & Spencer’s most famous cake might be branching out. A new image proposes a radical new format for a key component: a block of Colin the Caterpillar buttercream. Not in a tub, but a 250g block wrapped in paper, exactly like butter. This is a new idea.
The packaging suggests a move into home baking ingredients, allowing people to use the signature M&S frosting on their own creations. The caption that accompanied the image was simple: “Imagine this on a cake!”. For anyone who has ever wished for more of the good stuff, this moves Colin from a finished party piece to a creative starting point. A block of buttercream is a baker’s ingredient. It’s a statement.
The Caterpillar Empire
Colin the Caterpillar is more than a single product. He is an entire ecosystem. For years, M&S has expanded the range far beyond the original chocolate log cake launched in 1990. There are Giant Colin the Caterpillar cakes for bigger gatherings and half-size Colins for smaller ones. You can buy bags of Mini Colins, which are effectively single-serving caterpillar segments.
The brand also includes Colin the Caterpillar Faces—just the white chocolate part—and a whole range of gummy sweets, sours, and chocolate gifts. This constant expansion is a core part of the brand’s strategy, which also includes his partner, Connie the Caterpillar. A new component product would fit right in.
A White Chocolate Variant
The proposed flavour is White Chocolate. The original Colin is, of course, a milk chocolate creation with a solid white chocolate face and feet. M&S has a long history of creating seasonal and limited-edition versions of the cake, often involving flavour swaps or cosmetic changes.
White chocolate variants of popular confectionery are a classic move, and Colin himself has appeared in different guises for Christmas, Halloween and Easter. A white chocolate buttercream block feels like a logical next step, offering a flavour that is both familiar to the brand and distinct from the standard cake. It would be the first time the buttercream itself was the star.
