Pour about half of your batter into your greased loaf pan. Then, carefully pour the nutella on top of the batter and spread out, leaving about a 1/2-inch to 1-inch border around the edges.
Pour the rest of the batter on top of the Nutella.
Place dollops of Nutella on top of all the batter and swirl with a knife.
Bake at 350° F for 50-60 minutes. Make sure a toothpick inserted into the very center comes out clean, as the edges will bake before the center.
