Bakers across the city are being asked to get their mixing bowls ready for the Preston Guild.
Organisers want to create a map of the most famous landmarks in the city made out of cake.
Forty teams or individual bakers are needed to create a 50 square metre edible map of Preston, using icing instead of mortar.
The challenge, called Preston Cake City, is the idea of Simon Preston.
He said: “We want as many people as possible, including those whose last run-in with cookery was in a home economics class, to try their hand at baking their favourite Preston sights.
“Teams or individuals can make exact replicas of say, the bus station or Avenham Pavillion, or create an artistic impression of their chosen building, but they had better be quick if they want to make sure they can claim their spot on the map for their chosen building.”
The event is part of the Square Food Festival which takes place in Winckley Square on Saturday 1 September and Sunday 2 September.
Stella Hall, Preston Guild festival director says: “What better way to celebrate the abundance of great food made and served in Preston than making an edible map of the city with all our finest landmarks recreated.”
Those who want to take part can register online at the Preston Cake City website and stake a claim for the landmark they want to build out of cake.
