Consumers will be able to use licensed characters or order handmade personalised cakes. Prices range from £24.99 to £48.99.
The concept is being tested in 15 Scottish stores before being rolled out nationally.
May & Raeburn is expanding distribution of a frozen cake range from Swedish supplier Almondy which was previously available exclusively in IKEA's cafés.
The cakes are free from preservatives and colouring, have no gluten and can be cut while frozen and defrosted in just 10 minutes.
