Saw this online at raspberricupcakes.com and made for my son's birthday. Absolutely fantastic! Be sure to check out her beautiful pictures of the finished cake. The chocolate cake recipe is the Devil's Food cake from David Lebovitz. The frosting tastes just like mint chocolate chip ice cream! Instead of cake flour, I subbed all-purpose flour and replaced 3T with cornstarch which worked well. The original recipe suggests chopping chocolate in a food processor. I do not recommend this, it's too hard to chop uniformly. I used 150 g Ghiradelli double chocolate bittersweet chocolate chips, which is slightly less than 1 cup. Regular semisweet chocolate chips would work just fine. This is not a difficult cake to make or decorate.
