Seed cake probably had another meaning, as given in an account by
Fifty years ago seed-time had also its festival, though on a lesser scale, as well as harvest. At the backend, when the early sowing had been completed, the farmer made a sort of feast for his men, the principal feature of which was ‘seed-cake’, which was given to each of them. The cake did not get its name from anything that it contained, for it was in fact an ordinary sort of currant or plum cake, but from the occasion. On these minor festivals the men had as much ale to drink as they liked, and right well they enjoyed themselves. This old custom has, I believe, now quite died out.
