I'd like to ask you ladies, is there a way of making chocolate sponge using a plain sponge mix? Is it true that one can substitute some of the flour for cocoa and get a choc sponge?
I have done that in other recipes, with no problems but haven't tried it in a sponge cake!
oh I see, in that case, what is the ratio in which you substitute the flour for the cocoa?
yes, it should work just fine. deduct 2 tablespoons of flour from your recipe, and use 2 tablespoons of cocoa -- sift it several times with the flour to blend before folding/adding into your other ingredients. it makes a nice, light brown cake with a wonderful flavour, especially if it's a butter sponge, but it also works for non-butter sponge cakes (cocoa doesn't contain enough fat to collapse the foam).
My standard sponge recipe is
6 oz self raising flour
To turn it into chocolate cake, substitute 2oz flour for 2oz cocoa
Thanks for those tips, guys. I'll give it a go!
