Unfortunately the people who ranted about 'rule of thirds' probably didn't know any more than to look at that as a 'rule'.
The real issue is that you need to understand how people see things and then from that you can decide where to place the centers of interest in a photo.
When someone looks at a picture, if the center of interest, the spot their eyes are drawn to, is in the center, their natural impulse is to look for its symmetry and, if it isn't symmetrical, to look around to try to understand why it is in the center.
On the other hand, if the COI is not symmetrical, people want a clue how to look at it, approach it. Pushing something against the edge makes it look squeezed in, less important and leaves lots of unimportant space so the best place to put the COI is somewhere between the center and the edge - hence the thirds 'rule'.
I think the cupcake looks better this way. The top, the COI, is at the thirds, there is a natural leading line drawing the eye to the top and it isn't squashed against the edge.
I darkened a light corner so the views don't slide out there and it looks good. Nice and sharp and very edible.
You might darken the really bright clovers (?) so they don't distract but it's still fne this way.
