Happy, happy birthday to my amazing sister! Because I bake for every holiday, birthday, or even just  Sunday night family dinners, my sister required that her birthday cake top them all. My first thought was an elaborate bright pink cake, but I had already covered that with my Pink Chocolate Ombre Cake, so I moved onto the next thought: a Ferrero Rocher layer cake! (Keep in mind that I had just tasted Nutella for the first time quite recently, so its decadent and addicting amazing-ness had just dug a special place in my heart! )
