Sometimes called Kentucky Jam Cake. This recipe seems to date to around the 1930s, influenced by the spice cakes of the Depression, but with ingredients suggesting people had a bit more money (since they could afford eggs and didn’t use prunes or raisins to reduce the sugar).
From a box sold in Canby, Oregon.
