STAFF made blue lemon drizzle cakes at La Croissanterie, in Osborne Road, Southsea.
Everyone wore blue clothes and served blue mayonnaise to customers.
Manager Andre Guedeney said: ‘We have been really successful this year - our mayonnaise is really popular.
‘All of our cakes have blue icing, and Tom’s family even popped in to say hello to us, which was fantastic.
‘We will definitely get involved in this great cause again next year.’
