HOWTO bake a Portal cupcake

Starshipminivan sez, "Finally, the promise of Portal has been fulfilled. These cupcakes are not a lie and you don't even have to listen to GlaDOS, just bake, decorate, and consume these mini flavor marvels. Perhaps the cake is a lie but the cupcake is at least a half-truth. These rich, moist cupcakes, topped with frosting and chocolate, are delicious mini replicas of the black forest cake seen in Portal. You'll be in heaven but 'still alive' after eating one."
