Tiramisu Crepe Cake

A coworker tagged me in a picture, asking if I can make this cake for her.  Crepe cake and tiramisu, how could I say no?!  Once I knew I was going to work with cognac and rum, I couldn't wait to begin.

She sent me the recipe from Tasting Table.  I made a few adjustments due to availability of ingredients.
