Birthday cake

A colleague had wanted to bake for her daughter's birthday but had no time in the end so she ordered a chocolate cake from me. This is not the usual chocolate cake that I make as she specially requested it to be the cupcake recipe that I usually used. As she was gonna feed 30 people, I had to buy a new cake tin to make this and estimation was not very good as it turned out to be a little "shorter" than I anticipated. Nevertheless, they all loved it!
