What are you're favourite recipes for a plain vanilla sponge and a chocolate fudge/mud cake? (if you are willing to share )
Otherwise how can i go about finding a recipe that is really trusty? I don't really have time or money to test lots of different recipes, is there a way of telling which sort of recipe will work for me?
And I always seem to struggle with finding a recipe for the right sized pan, any tips on changing a recipe to work with a different size?
I'm still in the process of developing a recipe for chocolate fudge cake and I don't really do sponge cakes, since they don't seem to be very popular here (am I right in guessing you're British?), so I can't really help with those specific recipes, but for general guidance on changing the batter to fit the pans, I have found The Cake Bible by Rose Levy Beranbaum very helpful. She also has basic recipes for chocolate and vanilla butter and sponge cakes that are set up for wedding cakes in easily scalable amounts. The book also has a chart explaining how to adjust leavening for different sizes of pans. She's a very highly esteemed baker and the recipes I have tried so far from her have worked very well.
If you search, you should also be able to find a thread in the recipe forum about a chocolate cake "scratch-off" where multiple different chocolate cake recipes get discussed and rated. (The internal search engine often isn't very good, but Google should be able to find it.)
I hope that helps!
