The Sticky Toffee Pudding Colin the Caterpillar Cake

A Classic Pudding Crossover

The Colin the Caterpillar cake is a fixed point in British culture. For decades, the M&S chocolate sponge roll has been the default centrepiece for office birthdays and children’s parties. While the core product remains a bestseller, the brand itself has expanded far beyond a single cake, spawning a universe of related sweets and merchandise. This is the context for the latest flavour proposal to catch the public eye: a Sticky Toffee Pudding Colin.

The design shows the familiar caterpillar form, but re-skinned for a classic dessert. The standard milk chocolate coating appears to be supplemented with a toffee-flavoured drizzle and fudge pieces in place of the usual Smarties-style sugar shells. The familiar white chocolate face remains unchanged. It’s a simple concept, merging one national institution with another.

The Colin Brand Extension

Creating new versions of Colin is standard practice for Marks & Spencer. The cake regularly receives seasonal updates for Christmas, Halloween, and Easter, but the brand’s true expansion is visible in the wider range of permanent products that use the Colin name and likeness.

The core cake is now just one part of a sprawling franchise. The confectionery aisle features multiple spin-offs, from Colin the Caterpillar Cola Gums and Cherry Gums to Fruit Sours and Sour Stomps. Smaller bites are covered by Mini Colin the Caterpillar Cakes and bags of Colin the Caterpillar Softies. The brand has even moved beyond edibles entirely, with a line of partyware that includes Colin the Caterpillar Paper Plates and Party Cups. This history of diversification makes a new flavour edition for the main cake seem like a very plausible next step.

Dessert-Flavoured Desserts

The choice of Sticky Toffee Pudding is a commercially savvy one. It taps into the current supermarket trend of cross-pollinating dessert categories. We see tiramisu-flavoured yoghurts, Black Forest gateau ice creams, and apple crumble biscuits. Brands are increasingly taking the flavour profiles of established puddings and applying them to other formats.

A Sticky Toffee Pudding Colin fits perfectly into this landscape. It combines two highly familiar, comforting products that appeal to a very similar demographic. It isn’t a challenging or experimental flavour pairing; it’s a low-risk fusion that feels like it should already exist on an M&S shelf.

What the real range looks like

The official M&S Colin the Caterpillar range is extensive. The Sticky Toffee Pudding version would be a flavour innovation for the main cake, joining the original M&S Colin the Caterpillar Cake and the M&S Mini Colin the Caterpillar Cakes. It sits separately from the wide array of spin-off confectionery, which includes products like Colin the Caterpillar Softies, Fruit Gums, and Sour Stomps.
