Cupcake experiments - flat or domed?

I've been reading a lot of blogs and watching a fair few YouTube videos as I plan some of the upcoming baking projects that I have in mind and in one, which I do not know, I came across the suggestion that if you wanted flat tops to your cupcakes you should cream the butter and sugar first, if you wanted domes then you used the all in one method.  Intrigued (and still bored from being house bound!) my little boy and I set out to devise an experiment to see if this was true.  We made a 2 ounce mixture each (that is 2 ounces each of butter, sugar and self raising flour with 1 egg and a splash of vanilla), he used the all in one method and I creamed.  We used different colour cake cases to ensure we knew which was which and put them in the oven with high expectations!

The result?  You really couldn't see any difference between the two methods.  The creamed is on the left and the blue on the right in the above picture.  They all tasted good though :)
