Cradle Cake with Mystery Ganache

I realize this is a week late posting.  Getting the pictures up is a bit tricky.  I must say the Cradle Cake in Rose's Heavenly Cakes was a stunning combination; light buttermilk cake wrapped within a delicate dacquoise.  The only bit of tweeking with the recipe involved a ten inch loaf pan and 70% Valrohna chocolate.  Topped, while warm from the oven, with unmarked frozen chocolaty caramely ganache, this cake reserved rave reviews.
