Finsbury has reduced the sugar across its licensed Disney celebration cakes by 40%.

The new range – which includes Star Wars, Marvel Avengers, Spider-Man, Disney Pixar Cars, Disney Princess and Frozen cakes – also contains 40% less sugar than similar rival products, said the firm.

Finsbury collaborated with Mumsnet, submitting the cakes for testing to its independent panel, which gave its approval. This makes the reduced-sugar cakes the first collection of bakery products to have this endorsement, according to the manufacturer.

“We have worked extremely hard, using our knowledge in licensed cakes and the expertise of our chefs to successfully reformulate the recipe in line with the guidelines set by Disney,” said Daryl Newlands, marketing manager at Finsbury Food Group.

“As one of the largest cake manufacturers in the UK, we believe it’s important we are giving our customers choice.  Although cake will always be a treat, we want to ensure that people of all ages have a choice that’s right for them and their lifestyle,” he added.

The new range will also feature Finsbury’s first chocolate character cake, featuring a chocolate sponge with chocolate flavour filling, topped with icing and an edible decoration.
