I bake fairly often and am considered good at it and I always do my sponges properly, spending ages creaming butter and sugar etc. Since I got my Kitchenaid I could really spend a long time even on a Victoria sponge as I didn't have to stand there the whole time.
Yesterday, though, I decided at the last minute to have pudding after dinner, and in two minutes flat I glugged a load of golden syrup in the bottom of a tin, whacked all the sponge ingredients in the KA together and beat them hell for leather until it looked like cake mix, then whacked it in the oven at whatever temperature it was on at already. I also used Aldi baking spread instead of butter 
I've just eaten the leftovers and blow me if it isn't the nicest, softest sponge ever. I mean, it's really good!
