When I have done these sorts of things, I have used wholegrain spelt flour, rather than wholemeal and padded it out with oat bran. With fruit, I used blueberries, I found it less like a cake and somewhat spongy. It was OK, nothing more. However, I dropped the blueberries and added grated parmegano cheese. Now, that made for quite a good cheese scone substitute. Not as good as the real thing, but tasty and satisfying. But it was wholegrain flour. Some wholemeals seem to me as if they are white flours with some wholemeal added back in, rather than being wholemeal throughout the process, and often less is put back in than has been taken out.
