Aldi’s Cuthbert to Waitrose’s Cecil: Supermarket caterpillar cakes you didn’t know existed

Ever since it first went on sale 30 years ago, M&S’s Colin the caterpillar cake has become somewhat of a British institution.

The chocolatey treat is a failsafe for all ages and occasions, from kids’ and adults’ birthday parties (David Beckham and Dame Judi Dench are big fans), to farewell work dos. In fact, it’s proven so popular that M&S ​​has launched an entire range of spin-offs: Colin got himself a girlfriend back in 2016, Connie, and has since branched out into mini rolls, wedding cakes and seasonal versions for events like Halloween, Christmas , Easter, Valentine’s and Mother’s Day.

But trouble has been brewing for Colin in recent times as its status as the go-to caterpillar cake has come under threat from a bevy of imitators, including Aldi. Last year, M&S launched legal action against the budget retailer, claiming that its cake – called Cuthbert – infringed on Colin’s trademark. However, this week the two rivals called a truth, confirming an agreement has been struck that means Cuthbert will not appear again in quite the same form.

Despite this, Aldi has insisted that Cuthbert will be back. The discounter said in a tweet labeled #freecuthbert: “Getting out early on good behaviour, keep an eye out for Cuthy B this Spring”. while a spokesperson added: “Cuthbert is free and looking forward to seeing all his fans of him again very soon!”

Aldi isn’t the only supermarket to have cottoned on to the celebrity caterpillar’s popularity. A whole host of other grocers have designed their own versions, albeit with different names: there’s Tesco’s Curly, Waitrose’s Cecil, Asda’s Clyde and Morrison’s Morris, to name a few. If all this talk about cake has left you feeling hungry, we’ve rounded up all the different caterpillar cakes you can buy in supermarkets and online right now.



The OG caterpillar cake, Colin is made from a creamy chocolate sponge roll that’s filled with chocolate buttercream. It features a series of distinctive curves – which make it all the easier to cut 10 equal portions – and is covered in a milk chocolate shell.

It also has a decorative face made from solid white chocolate, which features milk chocolate eyes and a pink tongue, while its feet are also made from white chocolate. The cake is finished with a sprinkle of sugar-coated milk chocolate beans all over its back.

Feeding a bigger crowd? The supermarket also sells a giant version (£45, that serves 40 people and can be personalized with an iced message. If Colin’s sold out online, remember you can also pick one up in-store. Click here to find your nearest M&S.
