My boss fondly reminisces about the chocolate cherry cake his mother used to make for his birthdays, and I'd like to surprise him with one this year (next week). I've never made a chocolate cherry cake before! He grew up in Rochester, NY in the 60s/70s, so I'm hoping for something of that era/locale. Not sure if this means cake mix and pie filling (this thought grosses me out), or what. Any guidance or feedback would be greatly appreciated! Extra points if I can make it in a 9x13 pan and transport it to work (1.5 mi walk, crowded subway) without thoroughly damaging it. Thanks for your help!
