Lol, it is indeed and it's kind of involved, more than what I'm used to, which is why I make it only once or twice a year. You need a good four hours between prep and drizzling the sauce on the cake. The pb is indeed added before baking. After you make the chocolate cake batter, you make a pb filling and pipe it through a Zip Loc bag (cutting a 1-inch hole at a corner) around the top of the cake. Then you take a cup of batter reserved for topping the pb piping. The cake also involves a chocolate slurry that is the base for the cake batter. It's so delicious.
I, too, like chocolate and orange together.
