UK Cake Market Insights

In the United Kingdom, parents don't hold back when it comes to celebrating their children's birthdays. On average, they spend it for a child's birthday, with a significant chunk of that going towards food, decorations, and, of course, the cake.  From a simple dessert, the cake has evolved into a centerpiece for parties that is often themed, tall, and full of personality.

But alongside this spending trend, there’s also a growing cost-saving movement, especially in times of economic uncertainty.  On platforms, a growing number of parents are turning to cake transformations from the supermarket. With a little creativity—adding edible toppers, themed sprinkles, or layering two cakes—families can achieve impressive results without the high price tag of a personalized bakery creation.  Birthday magic is made more accessible by taking this practical approach.

Iconic Supermarket Cakes

One of the biggest ongoing trends in the UK kids gifts cake scene is the enduring popularity of iconic supermarket cakes—affordable, instantly recognisable, and surprisingly delicious.

At the top of the list is the legendary Colin the Caterpillar from M&S.  Since its introduction in 1990, Colin has evolved into a birthday tradition as well as a cake. With his playful smile, chocolate shell, and sprinkle-covered feet, Colin is loved by children and adults alike.  He has been accompanied by Connie the Caterpillar, Halloween and Christmas-themed versions, and even wedding cakes, demonstrating that his charm works at any age. Mini versions also make it easy to share Colin’s magic at school parties or smaller gatherings.

Meanwhile, supermarket dupe trends are exploding online.  One recent example that went viral is Tesco’s Matilda-style chocolate cake—a rich, gooey, fudge-covered masterpiece reminiscent of the iconic cake from the film Matilda.  Budget-friendly and photogenic, it’s being snapped up and styled by savvy parents all over social media.  Some even personalize it with personalized toppers or extra layers to match their party theme.

Boutique & Artisan Cake Delivery

In the UK, boutique and artisan cake delivery services are becoming increasingly popular with parents who want to elevate their child's celebration to the next level by providing something truly unique. Brands like Patisserie Valerie, Lola’s Cupcakes, My Baker, and Cutter & Squidge are redefining what a birthday cake for kid can be—offering handmade, high-quality, and themed creations delivered straight to your door.

What sets these cakes apart is the attention to detail.  You’ll find layers of rich sponge, luxurious buttercream, and edible decorations that look almost too good to eat.  There are even services that offer photo cakes, name personalization, or number shapes, giving each cake a unique feel.

Personalised & Character Cakes

A cake made just for a child brings a smile to their face like nothing else, which is why personalized and character cakes are so popular in the UK. Personalized cakes that are a reflection of their child's favorite shows, characters, and obsessions are becoming more popular among parents than ever before. These cakes go beyond simple decoration.
