Asked on 15 Aug 2021 by maincook42 how do you convert the recipe and cooking time for the coffee and walnut sponge cake from an 18cm round tin to a 20cm round tin? Lindsey, Food Editor replied Hello, You’ll need to do 1 ½ times the recipe for a 20cm sponge tins. It will still need about 30 minutes in the oven. Just check they spring back. Kind regards Lindsey Do you have a question for Delia or Lindsey? Why not ask your question now.
