Hay, I have a recipe for a 8-inch sponge cake which is 175g of flour,butter and caster sugar + 3 eggs.. but it is never deep enough as i have a deep pan. wanted to know any other quantities to make a perfect deep cake?
Instead of 175g and 3 eggs, use 330g each flour, butter, sugar, and 5 eggs. Increase your baking powder accordingly, add some milk or water (about 120ml). Split between 2 8" tins and bake for around 30-35 mins. Your cakes should come out around 2" high. I use 3" pans.
