Recently, my fairy cakes (cupcakes - whatever you want to call them) have started to peak high in the oven, and sink to the point of being saggy-middled (hmm, sounds so attractive, doesn't it?!) when they cool. Can anyone suggest what might be causing this? Never been a problem before. Could it be my oven playing up? FYI, I usually mix them in the food processor - would I get better results using my KitchenAid? Or my hand electric mixer? I just use the processor because I always have.
Any pointers would be v welcome. TIA!
