Chocolate Overload Cake - I made this for a co-worker of mine's birthday. We all take turns buying, or making, cakes for each other's birthdays at work. I volunteered to make Yvette's. She LOVES chocolate so what better cake to make her than one with lots of chocolate. This one is a double layer Devil's Food Cake with a chocolate buttercream filling, fudge frosting and semi sweet and white chocolate chips on top.
