The promises of chocolatey, crunchy, gooey deliciousness are blissfully fulfilled in this cake. The batters are a combination of the best, thickest, most satisfyingly creamy white chocolate and deep, dark chocolate batters around, with an abundance of Oreo cookies, white chocolate chunks, and dark chocolate chunks. And, if that is not enough to set your chocolate-loving tastebuds in a frenzy, it is filled and topped with a wonderfully creamy white chocolate cookie ganache.
