Few supermarket products have generated as much attention, humour and genuine legal drama as Aldi Caterpillar Cake.
What started as a budget friendly birthday staple quietly sitting in Aldi refrigerators has become one of the most recognisable products in British retail. From Sheffield to Southampton, families now actively compare caterpillar cakes before planning birthday parties.
As a Sheffield based food reporter covering supermarkets, consumer trends and family budgets, I have noticed something interesting. Shoppers are becoming more strategic with celebrations. They still want memorable birthdays, but they no longer assume spending more automatically means getting a better product.
That shift has helped Aldi Caterpillar Cake become one of Britain’s biggest supermarket success stories.
For many households, Cuthbert the Caterpillar is no longer simply a cake. It represents affordable celebrations during a time when families are paying much closer attention to value.
Whether you are organising a child’s birthday, planning an office gathering or simply curious about the famous M&S legal battle, this guide explains everything UK shoppers need to know.
What Is Aldi Caterpillar Cake?
Aldi Caterpillar Cake, officially called Cuthbert the Caterpillar, is Aldi UK’s chocolate sponge celebration cake.
The product consists of chocolate sponge roll, chocolate buttercream filling and a milk chocolate shell. Decorative sweets, a white chocolate face and colourful chocolate beans complete its recognisable appearance.
The cake is designed to serve approximately 12 people and has become one of Aldi’s most recognisable bakery products.
Unlike artisan bakery cakes, Aldi Caterpillar Cake was created to solve a practical problem. Families want birthday cakes that are affordable, attractive and easy to buy during their weekly shop.
Why Aldi Caterpillar Cake Became A British Icon
Britain has a unique relationship with caterpillar cakes. Very few supermarket products inspire genuine affection across multiple generations.
Children grow up eating them. Parents then buy them for their own children. That cycle creates long term emotional loyalty.
Aldi entered an already established market and succeeded by offering a lower cost alternative without sacrificing the experience consumers expected. That strategy proved extremely effective.
The Story Behind Aldi Cuthbert The Caterpillar
Marks and Spencer launched Colin the Caterpillar in 1990 and established the category that dominates supermarkets today.
Aldi later introduced Cuthbert as part of its value focused retail strategy. For years, Cuthbert quietly built popularity among budget conscious shoppers.
Everything changed in 2021 when Marks and Spencer launched legal action against Aldi over similarities between Colin and Cuthbert.
The dispute instantly became one of Britain’s biggest retail stories. Instead of staying silent, Aldi leaned into the moment with its viral #FreeCuthbert campaign.
The strategy generated enormous public support and transformed a legal dispute into a marketing masterclass.
The two retailers eventually reached a confidential agreement. Today, Cuthbert remains one of Aldi’s most recognisable products.

For most households, both cakes deliver a similar birthday experience.
The major difference is price.
Independent taste tests have repeatedly shown that many consumers struggle to reliably distinguish between supermarket caterpillar cakes. That is why value often becomes the deciding factor.
