I made this cake for my husband's grandmother's birthday. I had watched the latest Food Network Challenge with the Sweet 16 cakes and thought the guy's cake with all the different flavors sounded so good, so I tried to recreate it. I had alternating flavors of dark chocolate cake, oreo filling, vanilla cake, chocolate ganache, vanilla cake, oreo filling and dark chocolate cake. I added melted white chocolate to my regular buttercream and topped it all off with some chocolate ganache. Talk about heaven!
