Tower of Cake

My birthday cake of the year: alternate layers of Tartine Devil's Food and Baking Illustrated's Old-Fashioned Chocolate Layer, filled with fresh whipped cream mixed with Trader Joe's Morello Cherry fruit spread. Made for Heather, Margot, and Claire's 30ths, brought to new heights for my dad and Uncle Alan's 60th bday bash. Happy birthday, everyone!

(Having now made versions of this cake 3 times, I've determined the Tartine cake is tastier & bakes better than the Baking Illustrated. Whoever has the next bday is getting 100% Tartine, or, does anyone have a chocolate cake they recommend?)
