It’s Cherry Chip cake with a thin spread of ganache between layers and then frosted with a cherry buttercream frosting.
The cookbook author developed it because she missed the Cherry Chip cake mixes from her childhood. I too enjoyed those and was happy to try this cake. I assumed that the Cherry Cake mixes were no more, however when buying ingredients at New Seasons, the cashier told me that the Cherry Chip mix is still made and that New Seasons carries it. It was rather deflating news. I still made the cake from scratch anyway.
