Welcome to the Cake Decorators Q&A

If I want to downsize/upsize a cake I use the Ready Reckoner.
But my question how do you calculate the baking time for this cake and I presume the oven temperature will remain the same?

Thank you.

The temperature will remain the same, however there is no fast rule for the timing. I usually keep an eye on the bake first time round and make a note of it for subsequent bakes.
