Welcome to the Cake Decorators Q&A
I normally use a madeira cake mix for deep cakes but can I use victoria sponge mix? If so, what recipe can I use for a 14" square tin please?
Can you also tell me oven temp and length of time please. Thank you
Take a look in the baking section for Mrs Jones’ deep vanilla cake recipe. Mrs Jones recommends adding an extra 10% flour to her recipe if you intend icing it. She also has her madeira recipe which is slightly less traditional with a more moist texture.
I definitely would not recommend baking one deep 14” cake. That amount of batter would take a long time to bake. As it is a square cake, the corners will be very vulnerable to burning with an additional risk of the cake being dry.
I suggest baking the cake in two shallower parts. Each part to bake for approximately 50 - 60 minutes, checking two thirds in of the time of baking. I’ve never done a 14” cake therefore, unable to give a definitive answer on timing. Keep to the give temperature of the recipe and keep an eye and nose on the baking. Hope this helps.🙂
Thank you. What temp of oven and length of time for Mrs Jones Madeira cake 12" square please as it doesn't specify?
I have answered this query in your 'Time' post.
