Perhaps more one of the seeded "breads" - a relative came back from California a few years back having had a "seed bread" - couldn't tell me what was in it - but I made a bread with added poppy seed, celery seed, pepitos, sunflower, sesame seed that turned out very well.

I think of the seed cakes in Tolkien's work as being a scone-type with heavy additions of one or more of the above.
