my cake did not look nearly as beautiful when cut (or when not cut) but it was still delicious. it was extremely rich, but balanced by the chocolate chip cookie dough ice cream we had to accompany it, it was just right. i also wish it would have been a little more moist on the inside (the cake layers fell apart), but - it wasn't. i left it in for 20 minutes and it wasn't done, so 5 more minutes and...too much. bummer.
also, for the whipped ganache, i used peanut butter and had it whipped to what looked like the PERFECT consistency. i also didn't have the right chocolate cacao %'s, so i added some powdered sugar. i decided to throw in the last few tablespoons of heavy cream i had and - boom. too. much. whipping. ganache was grainy and stiff. total. total. bummer. i ended up heating it a little to make it more spreadable (actually worked) but only did this when applying the chocolate shards.
speaking of the shards. they really were not that hard to make. probably the easiest part of the whole cake, though a little time consuming.
you can grab the recipe from design*sponge here. definitely want to attempt to make this again and 1) not overbake 2) not overwhip and 3) use the correct chocolate cacao %'s.
