Until recently I had no idea. I thought that they were just different words for the same thing.
It was only until I thought I’d make some cupcakes that I discovered that they are different, in both ingredients and texture.
Not hugely, but still a slight difference.
A fairy cake is light and fluffy, whereas a cupcake is slightly denser in texture due to the addition of plain flour to the mix.
Could this analogy also be true of the difference between men and women?
