Banana Muffins with Nutella Ganache

I looked in my cabinet today and was a bit shocked to find a neglected jar of Nutella hiding in the back. After all, how does one ignore Nutella? Nut-freaking-tella! T introduced me to this luscious hazelnut spread a handful of years ago when we used to live together. Many a college meal was comprised of Nutella sandwiches thereafter.

Rich, creamy Nutella, I would like to start an affair with you. The lustful, wild abandon type. I promise to never forget you in the cupboard again. You are not deserving of such neglect!
